The Balmain 5 Week Treatment contributes to the regeneration and revitalization of hair over five weeks and is characterized by its long-lasting effects. This hair treatment serves as a 5-week course for home use, helping hair achieve a youthful and radiant appearance. Silk protein provides optimal moisture for the hair and reconstructs damaged protein chains in the most natural way. Silk protein contains 17 of the 19 amino acids found in hair, making it nearly identical to the hair's own protein. To enhance the effects of the silk protein, the formula is enriched with succinic acid, a natural ingredient that can penetrate deep into the hair. It promotes the absorption of silk proteins and forms a protective layer around each individual protein chain. The combination of these two effective and active ingredients results in long-lasting hair reconstruction. The treatment includes 5 tubes of 20 ml each. Application: Use one tube once a week. Apply the contents to the hair and leave it on for 10-15 minutes. Then rinse thoroughly.
