Colouring hair after a keratin treatment?
Is it safe to bleach the hair after having a keratin treatment? How long should I wait before bleaching my hair? or even colouring (highlighting my hair)?
Two-Three weeksby: Sara
You need to wait two-three weeks before you do any other chemical treatments including coloring. For best results always do the coloring before Keratin treatment. After treatment the Keratin coat your hair like a thin layer of film and colorants might not penetrate the hair they way it should. Either wait three weeks or do it before. With bleaching, the effect is the same. You might get patchy results!
Two weeks before and two weeks afterby: Stylist
No coloring for two weeks before and two weeks after on any type of keratin, relaxing or any other chemical treatment.
