Hair that is curly rather than kinky can be changed into pin-straight tresses with a Japanese hair straightening treatment. A special chemical solution that breaks down each hair’s shape is used to saturate the hair. After approximately 20 minutes, the solution is rinsed out and the hair is dried with a blow dryer. Then it is carefully flat-ironed in small, separate sections. Once all the hair has been ironed flat, a neutralizer is applied that locks in the straightness.
