Q: How soon after having YUKO hair straightening can the hair be washed or get wet?
A: You can wash or wet your hair 2 day after this treatment is done. Blow dry 100% after shampooing every time to maintain straightness.

Q: How does YUKO hair straightening work?

Correct application by a trained and experienced stylist will give you the results you desire. Make sure you consult a stylist experienced in YUKO hair straightening if you have any concerns.

Q: Does YUKO hair straightening work on any type of hair?
A: Yes, YUKO hair straightening works on all hair types. The best candidate for YUKO hair straightening is healthy virgin hair or hair that has been colored by a stylist with single process color. (not home color)

Q: Can I have YUKO hair straightening and color at the same time?
A: No. Color your hair at least 2 weeks before or after the straightening procedure. Applying both chemical treatments simultaneously will result in hair damage, so do them separately to avoid undesirable results.

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?
A: No. We do not recommend getting YUKO hair straightening except on new growth. Please wait 3-4 months until the relaxer/Brazilian/Keratin Treatment coating is completely off your hair to get YUKO hair straightening.

A: YUKO offers home care products that will work optimally on hair that has been treated with YUKO hair straightening. Please refer to our After Care Tips for information on daily hair care.

Q: How is YUKO Japanese hair straightening different from other Japanese hair straightening methods?
A: In addition to being a state-of-the-art hair straightening system, YUKO hair straightening is also a recognized technique of restoring health to the hair. The YUKO Hair Straightening procedure holds a patent in the US, Japan, New Zealand, Turkey and other countries.

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.
