Keratin is a protein that the body produces naturally and too little of it can weaken the hair. This means that a keratin treatment will help repair and nourish your hair from root to tip. It also prevents frizz, increases shine by enhancing the hair's natural colour and leaves hair feeling softer and stronger.
Keratin is a multifunctional protein with many benefits for your hair. Applied as a conditioner, it allows you to smooth, soften, detangle and fight frizz, protect them from the heat of the hair dryer or iron, restore their shine and repair them by restructuring the fiber capillary ... in short, the wonder protein for your hair!
