Designed for the first stage of the procedure.
During the first stage, thanks to the enhanced formula combining 2 types of relaxants: TGA+CYS, there is rapid opening of the cuticles and penetration of active ingredients inside the hair, restructuring the existing disulfide bonds. The formula contains a patented complex of microproteins (NUTRILAN® KERATIN W PP keratin + wheat proteins GLUADIN W40 + collagen), which significantly strengthens the hair shaft, "compensating" for the deficit of natural protein and increasing the strength and elasticity of the hair. With an amino acid composition closely resembling that of human hair, it reduces breakage and solubility in alkaline solutions. NUTRILAN® KERATIN W PP has proven effectiveness in cold-wave hair styling products as an excellent protector.
