PROTICUTE H GAMMA is a γ-keratose derivative extracted and purified while maintaining the amino acid balance without destroying the molecular state of the same keratin as hair and scalp as much as possible. It protects hair and prevents the damage during bleaching and perming. It has an average molecular weight of 20,000 to 40,000, has almost no peculiar odor, and is stable in a wide pH range, so it is very easy to use.
