Sebastian Professional Twisted Curl Elastic Mask 150ml is a deep-conditioning treatment built specifically for curly, coily and wavy hair. The salon-strength formula combines shea butter and a Flexi Alg™ marine algae complex with botanicals including Irish moss, calcium, panthenol and vitamin E to lock in moisture, restore elasticity and tame frizz — leaving curls more defined, bouncy and easier to style.
