Cadiveu BRASIL CACAU Anti Residue Shampoo pH 9 Deep cleansing without damaging the hair. Advances formula for hair nutrition. Keratin Hair deposit compound. Smoother, stronger and shiner hair. Direction: Apply to wet hair, massage and leave on for 5-10 minutes. Rinse thoroughly. BRAZILIAN KERATIN RECONSTRUCTION Cocoa, Keratin, Panthenol, pH 2.8 (acid - decisive factor for the smoothing process). HOW IT WORKS: The smoothing effect is provided through the rigorous application of the 3 steps: the ANTI RESIDUE SHAMPOO with pH 9 (alkaline) opens the hair shaft cuticles so that the BRAZILIAN KERATIN RECONSTRUCTION with pH 2.8 (acid) will be effective. The heat provided by the hair dryer and the hair straightener activates the ingredients which are then fixed to the hair. The DEEP CONDITIONING MASK with pH 4.5 finally equilibrates the hair pH values keeping hair straight and reconstructed for longer times (up to 2 month).
