A perm can’t be fully reversed with home remedies because the chemical bonds in your hair have been permanently restructured. But you can significantly relax the curl pattern, speed up how quickly the perm loosens, and manage the grow-out process so your hair looks and feels more natural. Most perms last three to six months on their own, and with the right approach, you can shorten that timeline while keeping your hair healthy.
Why Perms Don’t Simply Wash Out
Understanding what happened to your hair helps explain why no single home treatment will undo a perm overnight. During the perming process, a chemical solution breaks the strong sulfur bonds (called disulfide bonds) that give your hair its natural shape. While your hair is wrapped around rods, a second solution locks those bonds into a new curled position. Roughly 70 to 80 percent of the broken bonds re-form in this new configuration, creating a structural change that goes deep into the hair fiber.
This is why the curl is “permanent” until new hair grows in. Natural methods won’t snap those bonds back into their original arrangement the way the chemicals rearranged them in the first place. What they can do is relax, stretch, and weigh down the curl over time, making it progressively less noticeable.
Frequent Washing to Loosen the Curl
One of the simplest ways to speed up the breakdown of a perm is to wash your hair more often. Frequent shampooing strips the oils and moisture that help curls hold their shape, and repeated water exposure gradually weakens the restructured bonds. This is actually the opposite of what stylists recommend for maintaining a perm: they advise extending the gap between washes as long as possible because frequent shampooing damages the curl’s longevity.
Use a clarifying shampoo rather than a gentle or sulfate-free formula. Clarifying shampoos are designed to strip buildup, and they’ll pull moisture and product residue out of the hair more aggressively. Washing daily or every other day with a clarifying shampoo will noticeably loosen most perms within a few weeks. Follow up with a deep conditioner every time, since this process dries hair out considerably.
Deep Conditioning and Moisture Treatments
Heavy moisture is your best friend during this process. A deep conditioning mask once a week helps counteract the dryness that comes from frequent washing and heat styling. But beyond damage control, heavy conditioners and oils also weigh curls down physically, stretching them out and reducing bounce.
Look for rich, heavy formulas rather than lightweight curl creams (which are designed to define and hold curl pattern). Coconut oil, olive oil, or a thick hair mask applied generously and left on for 20 to 30 minutes before rinsing will soften the curl and add weight. Some people wrap their hair in a warm towel or shower cap during the treatment to help the product penetrate more deeply. Over several applications, this combination of moisture saturation and added weight gradually relaxes the curl pattern.
Blow Drying and Brushing Straight
Mechanical straightening is the most immediately visible way to reduce the appearance of a perm. After washing, towel-dry your hair gently, then blow dry while pulling it straight with a round bristle brush or paddle brush. Start at the roots and work your way down, keeping tension on each section as you dry it. For thick or long hair, clip the top half up and dry the bottom layers first, then release the top and repeat.
This won’t change the underlying bond structure, so the curl will return after your next wash. But consistent tension drying does train the hair over time, and each cycle of washing, conditioning, and blow drying straight will leave the curl a little looser than before. Using a low or medium heat setting helps minimize damage, which matters because permed hair is already more fragile than untreated hair.
Why Baking Soda Is Not Worth the Risk
You’ll find plenty of advice online suggesting baking soda paste as a natural perm remover. The logic sounds reasonable: baking soda is alkaline (pH around 9), and alkaline conditions are what break disulfide bonds during the perming process, so maybe it can undo them too. In practice, this causes far more harm than good.
Your scalp’s natural pH sits around 5.5, and research shows that products with a pH above that level can damage the scalp. Baking soda’s pH of 9 is significantly higher, and its abrasive crystal structure can physically tear hair fibers, leading to split ends and breakage. It strips natural oils aggressively, increases static and friction between hair strands, and forces the hair cuticle open in a way that causes excessive water absorption, which weakens already-compromised permed hair. For people with dry skin or conditions like eczema, it can also irritate the scalp. The small amount of bond disruption you might get is not worth the damage.
Apple Cider Vinegar Rinses
Apple cider vinegar rinses are a safer option, though they work differently than many people expect. Vinegar is acidic, so it won’t break the disulfide bonds that hold the perm in place. What it does is smooth and close the hair cuticle, reducing frizz and adding shine. Stylists have actually used vinegar rinses on fresh perms for decades to close the cuticle and neutralize odor, without damaging the curl.
A vinegar rinse (one part apple cider vinegar to two or three parts water, applied after shampooing and rinsed out after a minute or two) is a good addition to your routine for keeping permed hair manageable during the grow-out phase. It won’t remove the perm, but it helps your hair look smoother and less frizzy as the curl loosens from other methods.
Protecting Your Hair During the Process
Permed hair has already been chemically stressed. The protein structure is compromised, making it more fragile and prone to dryness and breakage. Aggressively trying to strip the perm out with harsh methods, excessive heat, or chemical treatments on top of the perm can push your hair past its breaking point, literally.
A protein treatment every two to three weeks helps restore some structural integrity while you’re working to relax the curl. These treatments temporarily fill in gaps in the hair’s protein framework, reducing breakage and improving elasticity. Balance protein treatments with moisture treatments, since too much protein without enough hydration makes hair stiff and brittle.
Avoid layering another chemical process (like a relaxer or a second perm to “cancel out” the first) on top of existing perm damage. This is one of the fastest routes to severe breakage and hair loss.
The Grow-Out Timeline
Even with all of these methods combined, the most reliable way to fully eliminate a perm is to grow it out. Hair grows about half an inch per month on average, so depending on your hair length, a complete grow-out takes anywhere from several months to over a year. The perm itself typically loosens significantly within three to six months through normal washing and wear, with tighter perms lasting longer than looser waves.
During this period, regular trims every six to eight weeks remove the oldest and most damaged permed ends, gradually replacing them with your natural texture. Many people find that a combination of frequent washing, deep conditioning, and periodic trims makes the transition manageable without any single dramatic step. Swimming in chlorinated pools or saltwater also accelerates curl loosening, since both strip moisture and stress the hair’s bond structure, though they dry hair out in the process.
The realistic expectation is that natural methods will soften and relax a perm over weeks, not remove it in a single session. Consistent effort with washing, conditioning, and gentle straightening techniques yields the best results while keeping your hair intact enough to look good during the transition.
