Is Hydra Lock suitable for sensitive or dry hair types?

The shampoo is designed to hydrate and smooth dry hair, and its conditioning agents are gentle, but the presence of fragrance, synthetic colorants and preservatives can irritate sensitive scalps, so a patch test is advised.

What benefits do silk amino acids provide in this shampoo?

Silk amino acids penetrate the hair shaft to reinforce protein structure, improve elasticity, reduce breakage and impart a silky sheen.

How often should Hydra Lock be used and does it contain any controversial ingredients?

It can be applied 2-3 times per week or daily if extra moisture is needed; the formula contains fragrance, synthetic dyes (CI 77510, CI 42090) and preservatives such as phenoxyethanol and sodium benzoate, which some consumers consider controversial.
