Keratin is a fibrous protein naturally present in hair, skin, nails, and other parts of the human body. It is made up of amino acids, including cysteine, tyrosine, methionine, and other compounds. In cosmetics, keratin is often used for its benefits in strengthening and revitalizing hair.

What are the benefits of keratin?

Hair Benefits:

  1. Hair Strengthening: Keratin strengthens the hair structure by filling in the gaps between the hair cuticles, thus reducing breakage and split ends.
  2. Improved Flexibility: By making the hair more resistant, keratin helps improve flexibility, shine, and manageability of the hair.
  3. Repairing Damaged Hair: Keratin treatments are often used to repair hair damaged by heat, chemicals, or other aggressors.
  4. Hair Smoothing: Some keratin-based smoothing treatments can help relax frizz and make hair smoother.
