Hot Head Heat Cap dramatically improves the results of your favorite deep conditioner, hair masque, oil, or other hair treatment. Without heat, your treatment can only do so much to improve the quality of your hair. Typically, the cuticle is closed, so the treatment can only work on the surface of the hair shaft. The results are minimal and superficial when compared to heat-enhanced deep conditioning treatments. Hot Head enables the hair cuticle to open for an extended period, allowing the treatment to penetrate the hair shaft, nourishing it from the inside out.
