How to find the right Hair Perms & Straighteners AI guide
Written by an AI model from its trained knowledge.
What the AI looks for in Hair Perms & Straighteners
- Chemical compatibility with your hair's history
- Do not apply a thio perm over hydroxide-relaxed hair, or a hydroxide relaxer over thio-permed hair. Treat only new growth on previously processed hair. The two chemistries are incompatible and overlapping processed hair is the main cause of severe breakage.
- Strand test before full application
- Test a hidden section with the full timing and the neutralizing step before every full application. It shows breakage, over-processing and allergic reaction before the whole head is affected.
- Neutralizer included
- The kit should include a neutralizing step: neutralizing shampoo for relaxers, peroxide-based neutralizer for perms. Without neutralization the chemical reaction continues and the hair stays weak.
- Strength matched to texture
- Use mild for fine, color-treated or fragile hair. Use regular for normal hair. Use super only for coarse, resistant hair. A formula that is too strong for the hair type dissolves too much of the hair's structure.
Brands that matter
- ORS: Mass-market no-lye relaxers built around scalp-protection steps.
- Dark and Lovely: Long-running home relaxer kits in several strengths.
- Mizani: Salon-oriented relaxers, including sensitive-scalp formulas.
- Ogilvie: The best-known home perm kit name.
- Zotos: Professional perm maker behind the Quantum line.
What to avoid
- Relaxing or perming hair that is freshly bleached or heavily lightened.
- Doing a relaxer and a perm or permanent color in the same session.
- Keratin smoothing products that list formaldehyde, formalin or methylene glycol.
- Using any relaxer on a scratched, irritated or recently scratched scalp.
Questions
Are chemical straighteners safe?
A large NIH study linked frequent use of chemical hair straighteners to a higher uterine cancer risk, and US regulators have scrutinized formaldehyde in smoothing products. Infrequent use, scalp protection and new-growth-only retouches reduce exposure, but they do not remove the concern.
