Hair straightened with keratin or treated with collagen or protein requires special care. That's why ARVEA has 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 preserve the effects of treatments to the maximum. It is also recommended for color-treated, fine, dry, curly or unruly hair that is difficult to straighten or damaged, and for sensitive scalps. Enriched with collagen, keratin and wheat proteins, it leaves hair supple, silky and luminous, frizz-free and weightless. Combined with the range's sulfate-free mask, hair will be even more radiant.
