1What's the difference between keratin treatments and relaxers?
Keratin treatments smooth and strengthen hair while keeping its natural texture, lasting 2-3 months and gradually fading. Relaxers permanently alter your hair's structure to make it straight, requiring touch-ups every 6-8 weeks as new growth appears.
2How do I know if my hair type can handle chemical straightening?
Fine or damaged hair needs gentler formulas and may not tolerate strong relaxers, while thick or coily hair typically requires stronger treatments. Do a strand test first—if your hair breaks or feels overly fragile, you might need a milder option or professional application.
3What should I look for in the product formula?
Check for added conditioning agents like argan oil or keratin to minimize damage, and avoid formulas with harsh sulfates if you have sensitive scalp. Sodium hydroxide relaxers are stronger but harsher than calcium hydroxide or no-lye alternatives, so match the strength to your hair's condition.
4Is it worth buying salon-quality products versus drugstore brands?
Salon brands often have better conditioning technology and more precise formulations that reduce breakage, making them worth it if you're doing this regularly. Budget brands work for occasional use, but they tend to be drier and harsher, so factor in potential repair costs if your hair gets damaged.
5How often can I safely use chemical straighteners on my hair?
Most relaxers should only be applied to new growth every 6-8 weeks—applying them to already-straightened hair causes severe breakage and damage. For keratin treatments, you can reapply every 8-12 weeks since they're gentler, but always wait at least 2 weeks between any chemical applications.
