Hydrolyzed Keratin
What is Hydrolyzed Keratin?
Hydrolyzed Keratin is a protein derived from the structural proteins naturally found in hair, nails, and skin. It is obtained by breaking down keratin into smaller, more manageable fragments through a process called hydrolysis.
This ingredient is commonly used in hair care products due to its ability to strengthen and restore damaged hair by replenishing the protein lost through styling and environmental stress. The evidence suggests that it can improve the appearance and feel of hair, but results can vary depending on individual hair type and condition.
When you see Hydrolyzed Keratin on a label, it typically indicates a focus on improving hair vitality and protection. It is generally considered safe for topical use.

Scout's take
Enzymatically broken-down keratin protein fragments small enough to penetrate the hair cortex and bind to damaged sites. Genuine repair activity (Wickett 1991), not just superficial coating like silicones.
