Especially gentle, Milk Shampoo for Dry Hair is formulated from non-abrasive agents. Made with 5% keratin, a naturally active substance, the shampoo is designed to affix this keratin to areas where the original keratin has been depleted. This dressing or sealing of damaged areas helps the original protective sheath to renew itself, regaining its smooth, regular structure over the entire length of the hair, from root to tip.
