Chemically Treated Hair

105 products

Repair. Protect. Maintain Your Treated Hair.

Chemical services — relaxers, perms, keratin treatments, color, and highlights — transform the hair's internal structure. That transformation requires an equally thoughtful maintenance routine. Chemically treated hair is more vulnerable to breakage, dehydration, and damage, and it fades faster without targeted protection. Our collection for chemically treated hair covers everything from bond-strengthening protein treatments to color-safe sulfate-free shampoos, so your investment in the salon stays beautiful, longer.

Frequently Asked Questions

Why does chemically treated hair feel dry and brittle?
Chemical processes change the hair's internal disulfide bonds and often raise the cuticle permanently. This makes hair more porous — moisture goes in and out faster, leading to dehydration and weakened elasticity.
How soon after a chemical treatment should I start a repair routine?
Immediately. Many stylists apply Olaplex No.2 in-salon right after a chemical service. At home, start with a bond-building or protein treatment within the first week and maintain weekly going forward.
Can I color and chemically straighten hair at the same time?
This is generally not recommended, as it stacks chemical stress on already-compromised hair. Most professionals recommend waiting at least 2 weeks between services and using bond protectors during both.
What's the difference between protein and moisture treatments?
Protein treatments rebuild the hair's structural integrity (great for chemically treated hair). Moisture treatments hydrate and soften. Chemically treated hair often needs both — alternate weekly between the two for best results.
