The bain Extentioniste is a strengthening shampoo and hair treatment that stimulates the growth of strong hair from the root. It helps the hair to grow in length, but also strengthens the hair. This shampoo is suitable for thinning and brittle hair and will repair and protect the fiber. The hair is perfectly cleansed and has the ideal environment to achieve the desired length.

Sensitized hair that is more susceptible to breakage is strengthened with this hair strengthening treatment. The internal structure of the hair will be rebuilt and sealed to offer better protection to the hair as it grows. 

Sizes: 250ml, 500ml
