Hair straightened with keratin or treated with collagen or protein requires special care. That's why ARVEA specially designed the 'Care & Repair' hair care range. The range's shampoo is formulated with gentle, sulfate-free anionic surfactants that gently cleanse and lather without aggression, to maintain the effects of treatments to a maximum. Also recommended for coloured, fine, dry, curly or unruly hair that is difficult to straighten or damaged, and also recommended for sensitive scalp. Enriched with collagen, keratin and wheat proteins, it leaves hair soft, silky, radiant, frizz-free and lightweight. When combined with the set's sulfate-free mask, hair will become more radiant
