Dry hair goes through a dehydration cycle. It absorbs moisture easily but then releases it too quickly. Without proper treatment, hair becomes more fragile and dryer over time. Inspired from the rainforest’s ever-replenishing moisture cycle, new Biolage Hydrathérapie continuously moisturizes hair to help stop the dehydration cycle with the anti-dry care of Aloe + Passion fruit. As part of our commitment, we have removed parabens where possible.
