Which type of hair relaxer is typically the safest for color-treated hair?

Keratin relaxers are considered one of the safest options for color-treated hair because they are formulated to infuse the hair with keratin, a protein that helps to restore and strengthen the hair. Unlike alkaline or traditional chemical relaxers, which can severely alter the hair's structure and may lead to damage, keratin relaxers work by smoothing the hair cuticle and reducing frizz without completely breaking the disulfide bonds in the hair. This makes them less harsh and more protective for previously colored hair.

Additionally, keratin relaxers typically have lower pH levels, which means they are less likely to strip color from the hair or cause further damage, making them a preferred choice for individuals who have previously colored their hair. This allows for maintaining both the health and vibrancy of the color-treated hair while achieving a sleeker look.
