Schwarzkopf BC Q10+ Time Restore Shampoo is a hair shampoo that gently cleanses and revitalizes mature, fragile, or very dry and brittle hair. Suitable for very dry hair types, this rich shampoo reactivates keratin production, promoting a more resistant and softer hair. Over time, the natural keratin production diminishes and the hair becomes weaker, limp, or dry. Schwarzkopf Professional's Q10+ complex was created to address the particular needs of mature hair: it helps to reduce visible signs of aging while stimulating the natural keratin synthesis of the hair. As a result, the hair looks fuller and softer as well as shinier.
