A refined, reusable extension method designed to create significant volume with minimal weight — featuring an ultra-flat, discreet finish.
Great Lengths Weft Extensions are defined by their ultra-thin, flexible spine — a paper-thin attachment point that sits completely flush against the head.
Unlike traditional wefts, this eliminates the visible “ledge” or bulk often felt at the back of the head. The result is smooth, seamless, and virtually undetectable in both look and feel.

The weft is sewn onto small, discreet sections of the natural hair using fine anchor points.
This creates a secure yet flexible foundation that moves naturally with the hair. As the natural hair grows, the weft is repositioned in the salon every 6–8 weeks to maintain placement and comfort.
This is the only weft system versatile enough to be worn across the full spectrum of hair types: from extremely fine to thick hair.
The discreet construction allows for controlled, tailored placement, making it suitable even for clients who would typically be unable to wear wefts.

Weft Extensions are designed to minimise tension through their lightweight construction and balanced weight distribution. The ultra-fine spine, lightweight hair, and discreet 2mm anchor points work together to eliminate pulling or strain, allowing the natural hair to grow freely and remain healthy throughout wear.
When applied correctly by a certified stylist, they offer a secure, comfortable result that protects the integrity of the natural hair.
Each weft contains a high number of strands, delivering exceptional fullness and visual impact.
However, because Great Lengths hair is delicate Indian hair, each individual strand has a finer diameter than that of Asian hair. This allows for greater density without increasing weight.
The result is voluminous hair that feels lighter, placing less stress on the natural hair while maintaining a full, luxurious finish.
This is a reusable system, maintained every 6–8 weeks.
At each appointment, the weft is gently removed, the anchor points are refreshed, and the weft is reapplied closer to the scalp — allowing the same hair to be worn repeatedly with consistent results.
Weft Extensions are ideal for adding density through the mid-lengths and ends. One pack creates natural volume.
Two packs deliver both volume and length for a more transformative result.

For clients seeking maximum volume without bulk, GL Weft Linea offer a uniquely refined solution — combining a completely flat finish with exceptional fullness and comfort.
Weft hair extensions are a reusable type of hair extension made from strands of hair sewn onto a fine, reinforced seam (or “weft”). This creates a continuous strip of hair that can be applied to add volume and length.
The weft is typically secured to the natural hair using small, discreet beads, allowing it to sit flat against the scalp and remain hidden beneath the natural hair. This creates a seamless, undetectable result that blends naturally with your own hair.
With premium systems such as Great Lengths, one weft is often used to add volume, while two or more wefts can be applied for a full transformation, including both volume and length. Multiple shades can also be combined to achieve a perfectly customised colour match.
The hair itself can last well over a year with proper care, however, weft extensions require maintenance every 6–8 weeks, as they are moved up to accommodate natural hair growth.
The main difference between hand-tied and machine weft hair extensions lies in how the hair is constructed along the seam (or “weft”).
Hand-tied wefts are created by manually tying individual strands of hair onto a fine thread. They are known for being lightweight and thin, but typically cannot be cut without unravelling, which can limit customisation.
Traditional machine wefts are produced by sewing hair onto a track using a sewing machine. These wefts are generally stronger and more durable, but can sometimes include “return hairs”—short hairs folded back into the seam—which can make the weft slightly thicker and, in some cases, less comfortable or more visible.
Premium systems, such as Great Lengths wefts, use proprietary technology to create an ultra-thin, flexible weft without return hairs. Often referred to in the industry as a “genius weft,” this design combines the durability of machine wefts with the thin, discreet finish of hand-tied extensions. The result is a lightweight, flat weft that sits comfortably against the scalp for a seamless, natural-looking finish.
A traditional sew-in weft is a weft of hair that is stitched onto a small, thin braid created using the client’s own natural hair. A beaded weft, by contrast, is stitched onto a row of small beads that have been attached to the natural hair, without the need for braiding.
We do not generally recommend traditional sew-in wefts, as braiding the natural hair can create kinking and place unnecessary pressure on the client’s own hair and scalp. When the hair is held in a tightly braided or bent position for an extended period, it can be less comfortable and may not allow the hair to grow out as naturally.
Our preferred method is the beaded weft. We use small beads with a soft inner rubber lining, which gently collect and secure the natural hair in place without the need for braiding. This creates a secure foundation for the weft while helping to minimise pressure, reduce stress on the hair, and avoid holding the natural hair in an unnatural bent position for too long.
The result is a more comfortable, discreet, and hair-friendly method that allows the client’s natural hair to grow out more freely and naturally.
There isn’t one extension method that is universally better, keratin bond and weft extensions are designed for different hair types, lifestyles, and results.
Keratin bond extensions are applied strand by strand, allowing for completely customised placement throughout the hair. This makes them ideal for creating a seamless, natural finish with full movement and flexibility. Because each bond is small and discreet, they are especially suited to clients who want to wear their hair up, add colour dimension, or achieve a highly tailored result. They also last longer between maintenance appointments, typically 4 to 6 months.
Weft extensions, on the other hand, are applied in rows and are designed to add instant volume and length more quickly. They are often faster to install and can be reused, making them a more flexible option over time. Wefts distribute weight evenly across the scalp, which can make them feel comfortable, particularly for clients with thicker hair or those looking for a fuller transformation. However, they do require regular maintenance every 6 to 8 weeks to keep them sitting correctly as your hair grows.
The biggest difference comes down to customisation vs convenience. Keratin bonds offer a highly personalised, discreet result with longer wear, while wefts provide quicker installation, reusability, and strong volume.
With premium systems like Great Lengths, keratin bonds stand out for their strand-by-strand precision, ethically sourced hair, and keratin composition that mimics natural hair. This allows for a more seamless blend and natural movement, particularly for finer areas or detailed work around the face.
Based on our experience, keratin bonds are best suited for clients wanting a fully customised, long-term result with maximum styling flexibility, while weft extensions are ideal for those looking for volume, reusability, and a quicker application with regular maintenance.
The cost of weft hair extensions in Australia can vary depending on several factors, including the length of the hair, the amount required, the colour blend, and the skill and experience of the stylist applying them.
As a general guide, the cost of the hair itself can range from a few hundred dollars for smaller volume services to $1,000 or more for a full transformation with added length and thickness. More customised colour work or longer lengths will typically increase the investment.
One of the key benefits of weft extensions is their reusability. While the initial investment may be higher, the hair can often be reused for 12 months or longer with proper care. After the initial application, ongoing costs are usually limited to maintenance appointments to move the weft up as your natural hair grows, which are typically required every 6 to 8 weeks.
The exact price will always depend on your individual hair and desired result. A personalised consultation is the best way to determine how much hair you’ll need and the total investment required.
Based on our experience, weft extensions are a cost-effective option over time due to their longevity and reusability, especially for clients looking for a long-term solution for volume and length.
Weft hair extensions are best for adding volume, thickness, and length quickly, particularly for clients with medium to thick natural hair.
Because wefts are applied in rows, they are ideal for creating fullness through the mid-lengths and ends, making them a popular choice for those wanting a noticeable transformation without the need for individual strand application. They work especially well for clients who wear their hair down or in softer styles and want a fuller, more voluminous look.
Weft extensions are also well suited to those looking for a reusable option. The hair can typically be reused for 12 months or longer with proper care, making it a great long-term solution. They are particularly effective for clients who are happy to maintain their extensions with regular move-up appointments every 6 to 8 weeks.
With premium systems like Great Lengths, wefts are designed with an ultra-fine spine attachment, allowing them to sit flatter and more comfortably against the head. Combined with the use of exclusively Indian Remy hair—known for its finer diameter and natural cuticle alignment—this creates a lightweight, natural-looking result with reduced tangling and improved movement.
Wefts are also a strong option for clients wanting to enhance thickness rather than just length, as they can add density efficiently across larger sections of the head.
Based on our experience, weft extensions are best for clients seeking maximum volume, reusability, and a faster application, while those wanting highly detailed placement, more flexibility in upstyling, or a fully customised finish may be better suited to keratin bond extensions.
Installing weft hair extensions typically takes between 30 minutes to 45 minutes per row, depending on the technique and level of customisation required.
Most clients will have between 1 to 3 rows installed, which means a full appointment can range from around 1 hour for a light volume service to 2–3 hours for a more complete transformation with added length and thickness.
The exact timing will depend on factors such as your hair density, the number of rows needed, and the overall result you’re trying to achieve. More customised colour blending or detailed placement may also add to the appointment time.
With high-quality systems like Great Lengths, the focus is on precision and placement to ensure the wefts sit comfortably, blend seamlessly, and maintain the health of your natural hair.
Based on our experience, while installation is relatively quick compared to some other extension methods, taking the time to apply the wefts correctly is essential for achieving a natural, long-lasting result.
Weft hair extensions can last well over a year with proper care, however they do require maintenance every 6–8 weeks, as they are moved up in the hair to accommodate natural hair growth.
With Great Lengths weft hair extensions, longevity is significantly enhanced due to the quality of the hair. Great Lengths does not use bleach during processing, meaning the hair remains true virgin quality with the cuticle fully intact. The cuticle acts as a protective, translucent shield around each strand, responsible for maintaining the hair's strength, smoothness, body, and natural shine.
In lower-quality hair extensions, the cuticle is often damaged or removed during processes such as bleaching. These extensions are typically coated in silicones to create an artificial shine. As these water-soluble silicones wash away over time, the hair can become dry, tangled, and difficult to manage.
Because Great Lengths preserves the integrity of the cuticle, the hair maintains its quality, softness, and shine for much longer—making it one of the most durable and long-lasting hair extension options available.
Weft hair extensions require maintenance every 6–8 weeks, as your natural hair grows and the weft moves down from the scalp. Regular move-up appointments ensure the extensions remain secure, comfortable, and seamlessly blended.
Many clients choose to coordinate their maintenance appointment with their colour service. In this case, the weft is carefully removed, the colour is completed, and the weft is then reapplied allowing for a fully refreshed result in one appointment.
At home, caring for weft hair extensions is simple and similar to caring for your natural hair. Many clients find wefts one of the easiest extension methods to maintain, as there is only one row (or a few rows), making it easy to shampoo both above and below the weft.
It is essential to use a professional extension brush, such as the Great Lengths brush, which is specifically designed to glide through the hair and reach the scalp without disturbing the weft or causing tension on the beads.
Using approved Great Lengths homecare products is also highly recommended. Unlike lower-quality hair, Great Lengths extensions are already in premium condition and should not be exposed to high-protein or heavy treatment products, as these can make the hair feel rigid, dry, or overly coarse. Proper homecare ensures the extensions remain soft, flexible, and long-lasting.
Weft hair extensions can experience some minimal shedding and tangling over time, but high-quality extensions are specifically designed to reduce this when properly cared for.
Shedding is typically very minimal with well-constructed wefts, as the hair is securely stitched into the track. Excessive shedding is usually a sign of poor-quality hair or incorrect handling. Tangling, on the other hand, can occur if the hair is not brushed regularly, exposed to dryness, or not maintained with the right products.
The quality of the hair plays a major role in preventing both shedding and tangling. With premium systems like Great Lengths, the hair is Remy, meaning all cuticles are kept intact and aligned in the same direction. This is essential, as it allows the hair to behave naturally, reducing friction between strands and significantly minimising tangling.
In addition, Great Lengths hair retains its natural cuticle layer, which helps protect the hair from dryness and damage. Lower-quality extensions often have the cuticle stripped, which leads to increased tangling and matting over time.
Proper home care is also key. Regular brushing with an extension-safe brush, keeping the hair hydrated, and avoiding product buildup around the weft will help maintain smoothness and prevent knots from forming—particularly near the track.
Based on our experience, when high-quality Remy hair with intact cuticles is used and the correct care routine is followed, shedding is minimal and the hair remains soft, manageable, and tangle-free throughout its lifespan.
Yes, weft hair extensions are highly suitable for thick hair and are often one of the most efficient methods for achieving added length and volume. For clients with naturally thick hair, more than one Great Lengths weft may be required to create a balanced, seamless result that matches the density of the natural hair.
One of the key advantages of the weft method is that multiple wefts can be stacked onto a single row if needed. This allows for greater volume without significantly increasing application time. As a result, the service time for a client with thick hair is often similar to that of a client with finer hair.
In contrast, methods such as tape-in or keratin bond extensions require each individual piece to be applied separately. For thicker hair types, this can significantly increase application time, as more bonds or tapes are needed to achieve full coverage.
This makes weft hair extensions a highly effective and time-efficient option for clients with thick hair who are looking to add length, fullness, and a seamless, natural finish.
Sleeping with weft hair extensions is simple, but following the right routine is essential to prevent tangling and maintain the condition of both your extensions and natural hair.
Before going to bed, it's important to gently brush your hair to remove any tangles, especially around the weft track. This helps prevent matting from forming overnight, which can be more common with longer or thicker hair.
Tying your hair into a loose braid or low ponytail is one of the best ways to protect it while you sleep. This keeps the hair controlled and reduces friction, which can otherwise cause tangling or dryness through the lengths.
Sleeping on a silk or satin pillowcase is also highly recommended, as it reduces friction compared to cotton and helps maintain the smoothness of the hair. This is particularly beneficial for extension hair, which does not receive natural oils from the scalp in the same way as your own hair.
It's also important to ensure your hair is completely dry before going to bed, especially around the weft area. Sleeping with damp hair can lead to tangling near the track and may affect both the extensions and your natural hair over time.
Based on our experience, a simple nightly routine of brushing, securing the hair, and minimising friction will significantly extend the lifespan of your weft extensions and keep them looking smooth and manageable.
Yes, weft hair extensions can be washed and styled much like your natural hair, as long as you follow the correct care routine.
You can shampoo, condition, blow dry, and heat style your weft extensions as usual. However, it's important to use extension-safe products that are gentle and free from harsh ingredients, as these help maintain both the quality of the hair and the integrity of the weft attachment.
When washing your hair, focus on cleansing the scalp carefully without rubbing or tangling the weft track. It's best to wash in a downward motion and avoid piling the hair on top of your head, as this can cause matting around the weft.
Styling tools such as straighteners and curling irons can be used on the mid-lengths and ends, but it's recommended to avoid excessive heat directly on the weft attachment itself. Ensuring the weft area is fully dry after washing is also important to prevent tangling or discomfort at the root.
Regular brushing, especially around the weft track, will help keep the hair smooth and prevent buildup or knots forming near the attachment.
With premium hair like Great Lengths, the quality of the hair means it often styles easily and holds shape well, helping reduce the need for excessive heat styling while maintaining a natural finish.
Based on our experience, clients who follow a consistent care routine can wash and style their weft extensions with ease while keeping them looking healthy, soft, and long-lasting.
Weft hair extensions can be suitable for fine hair when the correct method and materials are used. Great Lengths was originally founded to create volume rather than just length, and clients with fine hair are among the most common we work with.
Traditional weft extensions are often not recommended for fine hair, as they can place too much weight onto a single row of the client's natural hair. In addition, traditional wefts may contain “return hairs,” which can create a thicker, bulkier seam that may be visible, particularly in finer hair types.
Great Lengths wefts are specifically designed to be suitable for fine hair for several key reasons. Firstly, the spine of the weft is extremely thin, flexible, and discreet, allowing it to sit flat against the scalp and remain easily concealed. Secondly, the Indian hair used is naturally finer in diameter and slightly wavy, creating a soft, lightweight “veil effect” that delivers noticeable volume without excess weight.
Finally, the beads used in the application are approximately half the size of standard beads on the market. This allows the hair to be secured gently and precisely, reducing tension on delicate strands.
The result is a lightweight, high-impact extension method that adds volume and fullness without placing stress on fine or fragile hair.
Weft hair extensions are best suited to clients who enjoy maintaining their hair regularly and are happy to visit the salon every 6–8 weeks for move-up appointments. They are an excellent option for those who like to refresh their look frequently, whether through colour, styling, or overall hair transformations.
Wefts are particularly well suited to clients who prefer to wear their hair down or in low styles, as this allows the weft to remain fully concealed and blend seamlessly with the natural hair.
This method is ideal for those seeking volume and length with a reusable extension system, and who value a structured, salon-maintained approach to keeping their hair looking polished and consistent.
Weft hair extensions are not damaging to your natural hair when they are applied correctly and maintained properly.
The key factor in preventing damage is professional application. Weft extensions are typically installed using a row or “track” system, where the weight of the extensions must be evenly distributed across the natural hair. When this is done correctly, there is no excessive tension placed on the scalp or hair follicles, allowing your natural hair to remain healthy while wearing extensions.
However, damage can occur if the wefts are installed too tightly, if too much weight is placed on a small section of hair, or if maintenance is not kept up. Regular repositioning, usually every 6 to 8 weeks, is essential, as the extensions grow out with your natural hair and can create tension if left too long.
The quality of the hair itself also plays an important role. With premium systems like Great Lengths, the hair is ethically sourced and processed to maintain its integrity, which helps reduce tangling, matting, and stress on the natural hair. This contributes to a safer and more comfortable overall experience.
Proper home care is equally important. Regular brushing with an extension-safe brush, keeping the scalp clean, and using recommended products will help prevent buildup and tangling along the track.
Based on our experience, clients who follow correct maintenance schedules and aftercare routines can wear weft extensions long-term without compromising the health of their natural hair.
When applied correctly and looked after, wefts will not damage your own natural hair.
Weft hair extensions should not feel heavy when they are applied correctly, although you may notice a slight difference initially as you adjust to having more hair.
Because wefts are installed in rows, the weight of the extensions is distributed evenly across the scalp rather than concentrated in small sections. When applied properly, this balanced distribution helps keep the extensions comfortable and prevents unnecessary strain on your natural hair.
The design of the weft itself also plays an important role in comfort. Systems like Great Lengths feature an ultra-fine spine attachment, which allows the weft to sit flatter and more discreetly against the head. This reduces bulk at the root and contributes to a lighter, more natural feel when worn.
Hair quality is another key factor. Great Lengths uses exclusively Indian hair, which has a finer diameter—around 50% thinner compared to typical Asian hair. This results in a softer, lighter finish, meaning you can achieve volume and length without the extensions feeling heavy or overwhelming.
That said, the overall weight will still depend on how much hair is added. A full transformation with significant length and volume will naturally feel different compared to a lighter, volume-only service, but most clients adjust within a few days.
Based on our experience, when the correct amount of hair is selected and applied using high-quality systems, weft extensions feel lightweight, comfortable, and integrate seamlessly with your natural hair.
Weft hair extensions should not hurt when they are applied correctly, although you may feel a slight tightness immediately after installation.
This initial tension is normal, as the weft is secured close to the scalp to ensure a stable and long-lasting fit. For most people, this feeling settles within a few days as the scalp adjusts. Extensions should never feel painful, overly tight, or cause headaches: these are signs that the application may be too tight and should be checked.
Comfort comes down to correct technique. Proper sectioning, balanced weight distribution, and careful placement are essential to ensure the extensions sit securely without putting stress on the scalp.
Great Lengths systems are designed with hair health and comfort in mind, using high-quality hair that remains soft, lightweight, and manageable. This helps reduce pulling or heaviness, even when adding significant length or volume.
It’s also worth noting that sensitivity can vary from person to person. Clients with a more sensitive scalp may notice the extensions more in the first few days, but this typically subsides quickly.
Based on our experience, when weft extensions are applied correctly and maintained regularly, they feel comfortable to wear and integrate naturally with your own hair.
Yes, you can tie your hair up with weft hair extensions, but the types of styles you can comfortably wear may be more limited compared to methods like keratin bonds.
Weft extensions are applied in rows along the head, which can make the track more noticeable in higher or tighter hairstyles. Low ponytails, loose buns, braids, and half-up styles are usually the most suitable options, as they help keep the weft concealed and maintain a natural look.
Higher styles, such as high ponytails or slicked-back buns, may expose the track depending on placement and hair density. However, with careful application and the right styling techniques, some clients can still achieve these looks—particularly if they have thicker natural hair to help conceal the weft.
Placement plays a big role in versatility. A well-positioned weft can maximise styling options while still providing volume and comfort.
With premium systems like Great Lengths, the quality of the hair itself helps maintain a natural finish, but the attachment method will always influence how freely you can style your hair.
Based on our experience, weft extensions are ideal for clients who primarily wear their hair down or in softer, lower styles, while those wanting full freedom to wear their hair up in high styles may be better suited to keratin bond extensions.
Weft hair extensions should not be visible when they are applied correctly and blended properly with your natural hair.
The weft is installed in a track along the head, so visibility largely depends on placement, hair density, and how the extensions are styled. When positioned correctly, the weft sits discreetly beneath the top layers of your natural hair, allowing it to blend seamlessly and remain hidden in everyday wear.
However, in certain situations—such as very fine hair, high or tight hairstyles, or if the extensions have grown out—there is a possibility that the track may become more noticeable. This is why proper placement and regular maintenance are important to keep the extensions sitting close to the scalp and well concealed.
Hair density also plays a role. Clients with thicker hair tend to find wefts easier to hide, while those with finer hair may need more careful placement or may be better suited to alternative methods for maximum discretion.
With premium hair like Great Lengths, the quality and colour blending options help create a more natural finish, but the attachment method will always influence how invisible the extensions are in different styles.
Based on our experience, when weft extensions are professionally applied, maintained regularly, and styled appropriately, they remain discreet and natural-looking for most day-to-day wear.
