Coffee Premium is a system to make hair straight, rich in protein and amino acids. The formula is a perfect combination of glycolic acid from coffee extract, Luna Matrix and cationic polymers. These work intensively together to reduce the porosity of the hair shaft and create a flexible protective layer, creating more volume, balance and a smoother and smoother surface. This makes the hair straight, hydrated, soft and gets an intense shine. This product is free of "formaldehyde".
