A keratin leave-in treatment that nourishes and tames frizz, leaving hair feeling manageable, shiny and soft. Formulated with Pro-Keratin and Silk, Biolage KeratinDose Renewal Spray is targeted to care for over-processed, weak or fragile hair.
Hair is 90% more conditioned after one application when using the system of Keratindose Shampoo, Conditioner and Pro-Keratin Renewal Spray vs. a non-conditioning shampoo.
After using Keratindose Shampoo and Conditioner, spray the Pro-Keratin Renewal Spray onto wet hair and style as usual. Spray on dry hair as a finishing product for extra conditioning and softness.
