The Biologique Recherche Charlotte de Soin is a sophisticated treatment cap designed to enhance the effectiveness of hair-care rituals. Its unique polyethylene lining helps retain the scalp’s natural warmth, gently warming the hair and scalp during treatments. This increased warmth helps open the hair cuticles, supporting the penetration and absorption of active ingredients for enhanced product performance. Suitable for all hair types, the cap features an elasticated edge for a comfortable, secure fit during use. By optimizing the treatment environment, Charlotte de Soin helps leave the hair looking shinier, feeling softer, and appearing more supple. Practical and reusable, it is also conveniently machine washable at temperatures up to 30°C.
