The Sebastian Professional Hydre Intensely Hydrating Treatment Mask for Dehydrated Hair brings a five-minute ritual that helps smooth and hydrate very dry strands with moisture-focused care. The creamy texture works through lengths to soften the feel of the hair, adding a glossy shine and smoother finish. Designed as a weekly boost within your routine, the formula helps refresh the look of lengths, encouraging a more fluid, touchable result after rinsing.
