FunctionRepair Protein

What it is — Hydrolyzed Keratin (INCI: Hydrolyzed Keratin) is keratin protein broken into smaller peptides for conditioning use. Keratin is typically animal-sourced, though the exact origin varies by supplier, so check with the brand if that matters to you.

What it does — It is commonly used to temporarily smooth and reinforce the feel of the hair surface, filling in gaps along a damaged cuticle.

Typical use — It appears in conditioners, masks, leave-ins and bond-style hair treatments, and some skin products.

Who it suits / good to know — Often chosen for dry, damaged or chemically-treated hair. Protein effects are surface-level and build with regular use.

Safety — DHALIORA grades it low risk in its EWG-style, ingredient-by-ingredient review. This reflects the ingredient in general and is not medical advice; patch-test if your skin is easily irritated.
