Protein hair straightening is an advanced treatment that combines deep repair with long-lasting smoothness. Enriched with proteins and amino acids, it rebuilds the hair structure from within, restoring elasticity, shine and strength. The result is silky, frizz-free hair that looks healthy and vibrant. Suitable for all hair types, especially damaged, dry or frizzy hair, this treatment not only straightens but also nourishes and protects the hair.
