Good to know

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.
