Ask about the product and aftercare. Formulas differ, and many ask you to wait before washing and to use sulfate-free products afterward.
Common questions
How long does a keratin treatment last?
Often two to five months, fading gradually with each wash.
Is a keratin treatment the same as a relaxer?
No. Relaxers chemically change the hair’s structure for a lasting straightening effect, while keratin smoothing treatments reduce frizz and loosen the curl temporarily.
