A hydrating hair mask for the care of dry, dehydrated to very dry hair. The hair mask restores the moisture balance of the hair and scalp. Distribute a small amount of the mask over towel-dried hair. Knead well (rub your thumb along your index finger as if you were counting money). While kneading, the algae are crushed and an infusion of hydration is created. Let it soak in for 5 to 10 minutes. If necessary, cover with a warm/moist towel. Finally, rinse thoroughly. In case of a dry scalp, gently massage the mask into the scalp. Use together with the moisty seaweed hair bath for maximum results.
