Our keratin complex care shampoo is carefully formulated with hydroxyethyl cellulose and keratin. Designed specifically for deep penetration into the hair core, filling gaps and strengthening hair strands. It’s very convenient to use: after wetting your hair, apply an appropriate amount and massage the scalp and hair. Let it sit for 1–2 minutes, then rinse thoroughly. It can also deactivate scales to form a moisturizing barrier.
