📋 目次
1What type of chemical relaxer is best for long-term hair health?
Low-potassium hydroxide (KOH) relaxers are gentler and less damaging than traditional lye-based formulas. No-lye relaxers use calcium hydroxide or guanidine hydroxide and are better for sensitive scalps, though they may require more frequent touch-ups due to slower penetration.
2How long should I leave the relaxer in my hair?
Typically 15-30 minutes, depending on hair texture and product instructions. Overprocessing can cause breakage and scalp irritation. Always do a strand test first to determine the right processing time for your hair type.
3What’s the difference between a relaxer and a keratin treatment?
Relaxers chemically break and restructure hair bonds for long-term straightening, while keratin treatments temporarily smooth hair with protein and formaldehyde-like compounds. Relaxers last 6-8 weeks, keratin treatments last 2-4 months and require no heat for styling.
4Can I use a relaxer if I have previously chemically treated hair?
It depends — if your hair has been relaxed or bleached recently, it may be too damaged to handle another chemical process. Wait at least 8-12 weeks between treatments and always do a patch test to avoid severe breakage or chemical burns.
5What tools or aftercare products are essential for using a relaxer safely?
A comb for sectioning, gloves to protect your hands, and a neutralizing shampoo are must-haves. Follow with a deep conditioner and avoid heat styling for at least 48 hours to restore moisture and prevent further damage.
