Q: I have done a different brand of Japanese hair straightening before. Can I still have YUKO hair straightening done?
A: If the previous hair straightening procedure uses the same chemical (Ammonium Thioglycolate) as YUKO straightening solutions, applying YUKO will not be a problem. Please contact both companies to make sure chemicals are the same. Even if both use the same chemicals, the YUKO hair straightening process may not fully work if the hair is badly damaged already.
Q: I have done a relaxer/Brazilian/Keratin treatment before. Can I still have YUKO hair straightening done?

Q: How is YUKO Japanese hair straightening different from Brazilian/Keratin treatment methods?
A: YUKO Japanese hair straightening permanently straightens hair by physically changing the internal structure of hair. Brazilian/Keratin treatment temporarily coats hair with keratin to smooth hair. Brazilian/Keratin treatments will wash out in average 3 months, so you must visit a salon often to re-coat the hair with this method. Brazilian/Keratin treatments may contain hazardous chemicals which release highly carcinogenic gas. For more information on the danger of chemicals, please check OSHA Safety and Regulations.
