Excelsa Hydrating Shampoo is the first step in the innovative Collagen Treatment Kit. This high-impact treatment instantly restores the hair fiber thanks to its high concentration of low-molecular-weight proteins that easily penetrate the cuticle. Hair will immediately feel reconstructed, restructured, nourished, and protected. Use it before, after, or during any chemical treatment to restore life and shine to your hair.

Its formula contains: Panthenol, which, in addition to providing intense nourishment to the hair, is known for its emollient and soothing action on the scalp; Argan oil, which combats dehydration and dryness by strengthening fragile hair; and Hyaluronic acid, which gives hair a full and shiny appearance, protecting it from water loss.

How to use: apply to damp hair and massage, leave on for 4 to 6 minutes, then rinse.
