Frequently Asked Questions

Is Keratin better than Japanese Straightening?

Keratin smooths hair temporarily, while Japanese Straightening permanently changes the hair structure.

Which treatment lasts the longest?

Yuko, Liscio, and Cosme Straightening typically provide the longest-lasting results.

Can I color my hair after straightening?

Yes, but it's generally recommended to wait at least two weeks after your straightening treatment. Your stylist can advise the best timing based on your hair's condition.

Is straightening safe for damaged hair?

Professional consultation is important. Treatments like Acid Straightening or Keratin may be more suitable for weakened hair than permanent straightening systems.
