What is Yuko hair straightening?

According to Yuko USA, Yuko hair straightening is a U.S.-patented method for permanently straightening hair and re-texturizing hair to make it more healthy. Yuko hair straightening permanently straightens hair by changing the internal structure of hair.

Yuko hair straightening solutions are applied to the hair that alter the structure of the hair. A flat iron is used to apply heat to the hair to set it in shape. The whole process takes about three to four hours. According to Yuko USA, although most hair straightening methods damage hair, Yuko hair straightening restores hair and gives it a healthy shine as it straightens.
