Chemical, mechanical and thermal stress deeply damage the hair structure and lead to keratin loss. Hair becomes severely damaged: rough, dull and brittle. Vichy Dercos Kera-Solutions Resurfacing Shampoo has been specially developed for the intensive regeneration of damaged hair and the restoration of scalp health. At the heart of this innovation is the unique Pro-Keratin Complex, developed with a focus on biomimetic restoration of the hair fibre. Supported by Vichy's extensive research and development, this technology works at both the cuticle and cortex levels to seal microscopic cracks and strengthen the hair structure from within. Allantoin soothes the sensitive scalp and works together with the Pro-Keratin Complex to restore and smooth the hair fibre. The shampoo also protects hair from frizz for up to 48 hours and makes subsequent styling easier.
