If you've been blessed with naturally wavy, curly, or coily hair, but prefer to wear it bone straight, then you've likely heard of hair relaxers before. These lotions or creams work by chemically altering the structure of the hair for temporarily (usually about six to eight weeks) sleeker strands. It sounds intimidating, but the good news is that hair relaxers have come a long way since the 90s.
You can definitely have healthy relaxed hair," says Lyonisha Sanders, hairstylist, and owner of Lavish Salon & Extensions Bar. "Just like any other chemical hair manipulation, you just have to care for it properly with TLC.” While a professional stylist offers the safest option for chemical relaxing, there are plenty of over-the-counter options that will give you the sleek, straight strands you’re looking for.
If you’re a kitchen beautician confident enough to relax your hair at home, here are the best hair relaxers on the market.

What To Look For When Purchasing A Relaxer
Lye Versus No Lye
Relaxers that use lye have sodium hydroxide as the primary ingredient. These relaxers tend to be stronger and have more of a potential for burns, so they are typically applied by a licensed professional. However, they tend to be easier on the hair, since they don’t leave behind a mineral deposit. Most at-home relaxers are no-lye relaxers that use calcium hydroxide. These tend to be a bit milder on the scalp but could result in calcium buildup and dryness if not used properly. Whichever you choose, be sure to check in with a stylist regularly to ensure your hair’s health.
If you have a dry, sensitive scalp or sensitive conditions like eczema, you’re going to want to be sure to purchase a relaxer that is gentle and specifically formulated for scalp sensitivity. You should also be sure to pretreat your hair with a protective base and be sure to never apply the relaxer directly to the scalp.
Coarse hair and tighter textures are going to need a stronger formula while light waves and finer textures might need a more mild formula. Take your hair texture into consideration before choosing a relaxer.
How long do relaxers last?
Is it safe to relax hair at home?
“I don’t typically recommend over-the-counter relaxers due to them potentially causing the hair to develop calcium buildup which could eventually cause the hair to become brittle, dry, and break," says Sanders. "However, if one must do their relaxer at home, choose a mild formula that’s safe for a sensitive scalp.”
How can you keep relaxed hair healthy?
To keep relaxed hair healthy, Sanders advises seeking a professional stylist for regular hair maintenance, including getting ends regularly trimmed. Other recommendations include always keeping hair moisturized and conditioned and sleeping on a satin pillowcase or satin scarf.
