A plant protein used like keratin or silk: it coats hair to make it feel stronger and smoother. Cosmetic, temporary, plant-based.
Hydrolysed quinoa protein is broken into small peptides that bind to the hair surface, marketed as a plant-based alternative to animal proteins. Its effect is the same kind of temporary conditioning: less frizz, easier combing, a feeling of stronger strands.
Only ingredient-maker lab testing supports the conditioning claims. No evidence it affects hair growth or health.
