Very dry hair can be difficult to manage, lacking in shine and moisture. Inspired by the aloe plant that never seems to dry, Biolage ULTRA HYDRASOURCE Conditioner for very dry hair helps optimize moisture balance, intensely conditioning for healthy looking hair. How to use: Apply to wet hair and leave in 1-3 minutes. Rinse thoroughly. We recommend that you pair ULTRA HYDRASOURCE Conditioner with ULTRA HYDRASOURCE Shampoo for extra moisture and hydration. Recommended for fine to medium hair.
