Hydrolyzed rice protein
A plant, gluten-free protein used in conditioners and volumizers; we found no hair study for it.
Cosmetic ingredient
Cost $
What it is
Peptides from rice endosperm or bran. It is a cosmetic ingredient and a common vegan alternative to keratin or silk proteins.
How it works
We located no mechanism data. It presumably forms a film like other protein hydrolysates.
What the studies show
- No hair-specific study was located.
Side effects and safety
No hair-specific safety data were located.
Bottom line
A reasonable vegan, wheat-free substitute for other proteins, with no proof of benefit. Head-to-head comparisons with wheat or keratin proteins are missing. We are very unsure it does anything beyond coating the hair.
