Keratin Bond & The Science Behind It

Keratin bond hair extensions have become very popular recently. They offer a natural, long-lasting solution for enhancing hair volume and length. But what exactly is keratin, and why is it essential for these extensions? In this blog, we’ll explore the science behind keratin and its crucial role in hair health. Learn how they work to give you that flawless look.

What is Keratin and Its Role in Hair Health

Keratin is a tough protein composed of amino acids, especially cysteine. It forms the structure of our hair, skin, and nails. Keratin creates the hair shaft’s outer layer, called the cuticle, protecting the inner parts and keeping them moisturised. This prevents dryness and frizz. The strong bonds in keratin give hair its strength and flexibility, letting it stretch and bounce back without breaking. Additionally, keratin shields hair from UV rays, pollution, and heat styling damage, keeping it healthy and looking good.

How Keratin Bond Hair Extensions Work

Keratin bond hair extensions use the natural strength of keratin to attach securely to your hair. Great Lengths, a well-known brand, has perfected this method. They offer high-quality keratin bond extensions that are popular worldwide.

  1. Application: Small strands of hair extensions, each tipped with a keratin bond, are attached to sections of your natural hair. The bond is heated with a special tool, which melts the keratin and allows it to fuse with your hair.
  2. Bonding: As the keratin cools, it hardens, forming a secure bond between the extension and your natural hair. This bond is strong yet flexible, allowing for natural movement and styling.
  3. Seamless Integration: One of the big advantages of keratin bonds, especially those from Great Lengths, is how well they blend with your natural hair. The bonds are almost invisible, giving a very natural look.

Benefits of Great Lengths Keratin Bond Hair Extensions

  1. Long-Lasting: Great Lengths can last several months with proper care and maintenance, making them a cost-effective choice for long-term use.
  2. Natural Appearance: The flexibility and strength of Great Lengths keratin bonds allow for a natural look that matches the movement and texture of your own hair.
  3. Versatility: They can be styled just like your natural hair. You can curl, straighten, and even colour them to suit your desired look.
  4. Water and Sweat Resilience: Great Lengths keratin bonds expand when submerged in water or sweat, just like healthy hair follicles, ensuring a seamless and natural look even with those of active lifestyles.
  5. Minimal Damage: When applied and removed correctly by a professional, Great Lengths keratin bond extensions cause minimal damage to your natural hair, making them a safe and effective option.

Understanding the science behind keratin and its role in hair health explains the popularity of keratin bond extensions. These extensions utilise keratin’s natural properties to create strong, flexible, and nearly invisible bonds that enhance your hair. Additionally, as seen in the photo compared to a competitor (Great Lengths is the one above), each hair strand still has its keratin intact, unlike the overly smooth hair strand of the other. This means that the hair won’t feel squeaky after a while when the silicones wash off. While it’s crucial to choose quality extensions like Great Lengths, it’s equally, if not more, important to ensure proper maintenance. Using gentle hair products and following your stylist’s advice are essential to keeping your hair healthy and beautiful.
