You’ve probably heard friends talk about getting a relaxer, or maybe you’ve seen someone’s hair transformation from curly to sleek and wondered how they did it. If you’re curious about what relaxed hair actually is and whether it’s right for you, you’re not alone. This decision affects millions of people who want a different way to manage their curls and coils.
Hair relaxers have been around for over a century, dating back to Garrett Augustus Morgan in 1909. He accidentally discovered his hair straightening cream while trying to find a solution to ease friction on sewing machines in his tailor shop. After testing it successfully on a neighboring dog’s fur, he established the G.A. Morgan Hair Refining Company and began selling his product. Since then, relaxers have become a significant part of hair care, particularly for Black women and people with tightly coiled hair textures.
But here’s the thing: deciding to relax your hair isn’t something you should do on a whim. It’s a permanent chemical process that changes your hair’s structure, and it comes with both benefits and responsibilities. Whether you’re tired of managing your natural curls, looking for more styling versatility, or just want to switch things up, understanding what you’re getting into is crucial.
What Is Relaxed Hair?
Relaxed hair is hair that’s been chemically straightened using a lotion or cream designed to permanently alter your hair’s natural texture. Unlike heat straightening with a flat iron, which only lasts until your next wash, a relaxer changes the actual protein structure of your hair. Once you’ve relaxed your hair, it stays straight until it grows out or you cut it off.
The process works by breaking down the disulfide bonds inside your hair shaft—these are the chemical bonds that give your hair its natural curl pattern. When these bonds are broken and reformed in a straighter position, your curls, coils, or waves transform into smoother, straighter strands. Think of it as permanently rearranging your hair’s internal architecture.
Relaxers are also called perms in the Black community, though this can get confusing. When people with straight hair get a “perm,” they’re adding curls. When people with curly hair get a “perm,” they’re removing them. Same word, opposite results. You might also hear relaxers called “creamy crack” (a tongue-in-cheek reference to how some people love the results), chemical straighteners, or lye treatments.
The results typically last anywhere from six to twelve weeks before you’ll need a touch-up. As your hair grows, new curly hair emerges from your scalp, creating a visible line between your natural texture and the relaxed portions. This is when most people schedule their next salon visit to treat just that new growth.
How Do Relaxers Actually Work?
When a relaxer is applied to your hair, it penetrates through the cuticle layer (the outer protective coating) and into the cortex (the inner structure where your hair’s protein lives). The active chemicals in the relaxer break down those disulfide bonds we mentioned earlier, which are responsible for your hair’s natural curl pattern.
During what stylists call the “cooking” interval, your hair is combed straight while the relaxer does its work. This is controlled damage to your hair’s protein structure—and yes, there’s some irony in that phrase. The hair becomes significantly more pliable during this time, allowing it to be reshaped from curly to straight.
The processing time varies depending on your hair type and the strength of the relaxer, but it generally ranges between 10 to 20 minutes. Leaving it on too long can cause serious damage, including breakage, chemical burns, and even hair loss. Not leaving it on long enough means you’ll have uneven results with some sections straighter than others.
After the relaxer has worked to the desired degree, your hair is rinsed thoroughly. Regardless of which formula is used, relaxers are always alkaline with a high pH—anywhere from 10 to 14, compared to healthy hair’s natural pH of 4.5 to 5.5. That’s why it’s critical to neutralize the hair immediately with a special shampoo that brings the pH back down and stops the chemical process.
Types of Hair Relaxers
Not all relaxers are created equal. There are three main types, each with different active ingredients, strengths, and effects on your hair. Choosing the right one depends on your hair texture, scalp sensitivity, and desired results.
Lye Relaxers (Sodium Hydroxide)
Lye relaxers contain sodium hydroxide as their active ingredient, making them the strongest formulation available. They have an extremely high pH between 12 and 14, which means they work fast—sometimes too fast if you’re not careful.
These relaxers can straighten every hair type, from loose curls to the densest coils. Because they’re so powerful, they break down the protein bonds quickly, allowing for faster processing and rinsing. With a good neutralizing shampoo, lye relaxers tend to rinse out cleanly without leaving mineral deposits on your hair.
However, there’s a catch. The same strength that makes lye relaxers effective also makes them harsh on your scalp. Many people experience scalp irritation, burning sensations, or even chemical burns if the product touches their skin. That’s why stylists typically apply a protective “base” cream of petroleum jelly to your scalp before using a lye relaxer.
Lye relaxers are best suited for experienced professionals who understand proper timing and application techniques. They’re typically what you’ll get at a salon rather than in a home kit.
No-Lye Relaxers (Calcium or Guanidine Hydroxide)
No-lye relaxers use calcium hydroxide, potassium hydroxide, lithium hydroxide, or guanidine hydroxide instead of sodium hydroxide. They have a slightly lower pH of 10 to 12, making them gentler on your scalp and less likely to cause burning or irritation.
The guanidine hydroxide version isn’t pre-mixed. Instead, you combine a cream containing calcium hydroxide with an “activating solution” of guanidine carbonate right before use. This is the formulation you’ll typically find in boxed home relaxer kits.
While no-lye relaxers are easier on your scalp, they come with their own challenges. They can leave calcium deposits on your hair shaft, which blocks moisture absorption and makes your hair feel dry and brittle over time. You’ll need to use a clarifying shampoo regularly to remove this buildup, followed by a deep moisturizing treatment since clarifying shampoos can be drying.
Many people choose no-lye relaxers if they have sensitive scalps or have experienced burning with lye relaxers in the past. They’re also more accessible since they’re sold in drugstores and beauty supply stores for home use.
Thio Relaxers (Ammonium Thioglycolate)
Thio relaxers use ammonium thioglycolate (ATG) as their active ingredient—the same chemical used in permanent waves, but at a much higher pH and concentration. These are the gentlest relaxers available, with a pH around 8 to 10.
Unlike lye and no-lye relaxers that break disulfide bonds completely, thio relaxers work by reducing these bonds, which is a bit less harsh on your hair. They’re thicker and more viscous than other relaxers, making them easier to apply without dripping.
The downside? Thio relaxers only work effectively on fine hair or looser curl patterns. If you have dense, tightly coiled hair, a thio relaxer probably won’t give you the results you want. They also require a special oxidizing solution of hydrogen peroxide or sodium bromate afterward to reform the bonds in their new straight position.
Because they’re milder, thio relaxers can be left on longer without causing damage, giving you more control over the final result. They’re often recommended for teenagers, people with sensitive scalps, or anyone wanting to texturize rather than fully straighten their hair.
Benefits of Relaxing Your Hair
There’s a reason relaxers have remained popular for decades despite the rise of the natural hair movement. For many people, the benefits genuinely outweigh the challenges.
Easier daily management tops the list for most people. Relaxed hair requires significantly less time to detangle, comb, and style. You can wash your hair, apply some leave-in conditioner, and you’re basically done. No need for extensive twist-outs, braid-outs, or hours spent defining curls with gels and creams.
Your hair becomes less prone to knotting and tangling once those tight curls are smoothed out. Natural hair’s kinks and bends cause strands to wrap around each other, creating knots that can lead to breakage when you try to detangle them. Relaxed hair glides past itself more easily, reducing this friction and making combing a breeze.
Say goodbye to shrinkage. Natural hair can shrink up to 75% of its actual length when it dries, making your hair appear much shorter than it really is. Relaxed hair shows its true length without constant stretching techniques. For people who’ve been working hard to grow their hair long, this visible length can be incredibly satisfying.
Styling versatility expands dramatically with relaxed hair. Sleek ponytails, smooth bobs, pin-straight styles, and even heat-free curls with rollers all become easier to achieve. You’re not fighting against your natural texture—you’re working with a smoother canvas that holds styles longer and responds better to different techniques.
Humidity and weather become less of a concern. While natural hair can puff up, frizz out, or lose definition in humid conditions, relaxed hair maintains its straight texture regardless of the weather. Rain, humidity, sweat—none of these will cause your carefully styled hair to revert to its natural state (though you might still get some frizz).
The time savings can be substantial. What might take two hours of wash day routine with natural hair—including detangling, applying products, styling, and drying—can shrink to under an hour with relaxed hair. For busy people juggling work, family, and other responsibilities, this efficiency matters.
Challenges and Risks of Relaxed Hair
Before you rush to book that relaxer appointment, you need to understand the potential downsides. Relaxed hair isn’t all smooth sailing, and the risks are real.
Structural weakness is the biggest concern. When relaxers break down your hair’s protein bonds, they permanently weaken the hair shaft. Your hair loses some of its natural strength and elasticity, making it more prone to breakage, especially at the line of demarcation between relaxed and natural hair. This fragile point is where breakage most commonly occurs.
Chemical burns and scalp damage can happen even when relaxers are applied correctly. The alkaline chemicals in relaxers can cause irritation, burns, sores, and inflammation on your scalp. If the relaxer is left on too long or applied to an already irritated scalp, the damage can be severe. Some people experience permanent damage to hair follicles or scarring.
Over-processing is easier than you might think. If you relax your hair too frequently (more often than every six to eight weeks), you risk applying relaxer to already-relaxed hair, which causes it to become over-processed. Over-processed hair looks dry, feels brittle, has a reddish-brown discoloration, and breaks easily. It can also look limp, flat, and lifeless.
Your hair will become significantly drier than it was natural. Relaxers strip away your hair’s natural oils and alter its porosity, making it harder for moisture to penetrate and stay locked in. Without consistent deep conditioning and moisturizing, relaxed hair quickly becomes dry, dull, and prone to breakage.
Maintenance costs add up. Professional relaxer touch-ups every six to eight weeks can run anywhere from $50 to $150 or more, depending on your location and stylist. You’ll also need to invest in quality haircare products specifically designed for chemically treated hair—moisturizing shampoos, deep conditioners, protein treatments, and leave-in products.
Health concerns have emerged from recent research. Studies have found potential links between hair relaxer use and increased risk of uterine fibroids, breast cancer, and uterine cancer, particularly among women who use these products frequently over many years. While more research is needed to establish definitive causal connections, these findings have raised valid concerns about long-term relaxer use.
There’s also the risk of hair color complications. If you want to dye your hair, you’ll need to be extremely careful. Semi-permanent color is generally safe with relaxed hair, but permanent color or bleaching on top of a relaxer is a recipe for disaster. The combination of chemical processes is often too much for hair to handle, leading to severe damage or breakage.
How to Care for Relaxed Hair
If you decide to relax your hair, proper care isn’t optional—it’s absolutely necessary to keep your hair healthy and prevent damage. Relaxed hair demands more attention than natural hair in some ways, even though daily styling might be easier.
Moisture Is Your Best Friend
Deep conditioning every single time you wash your hair should be non-negotiable. This replenishes the moisture that relaxers strip away and keeps your hair soft and manageable. Look for thick, creamy deep conditioners formulated for dry or damaged hair, even if your hair isn’t damaged yet.
Between washes, moisturize your hair every two to three days—more often if it feels dry or brittle. Use lightweight, water-based leave-in conditioners or moisturizing creams that won’t weigh your hair down. After moisturizing, seal in that moisture with a light oil like coconut oil, argan oil, or a specialized hair oil. This technique is called “moisturizing and sealing,” and it’s crucial for maintaining hydration.
Don’t forget your scalp. A healthy scalp promotes healthy hair growth, so massage it regularly with lightweight oils to keep it moisturized and stimulated. Avoid heavy greases that can clog pores and prevent new hair from growing properly.
Balance Protein and Moisture
Your hair needs both protein and moisture, but getting the balance right takes some trial and error. Since relaxers damage your hair’s protein structure, regular protein treatments help rebuild strength and prevent breakage. Use a protein treatment about once a month to fortify your strands.
However, too much protein makes hair hard, crunchy, and brittle—a condition called protein overload. If your hair feels stiff or starts breaking after protein treatments, dial back and focus more on moisture. The key is finding the right balance for your specific hair.
Limit Heat Styling
Your hair is already chemically processed, so adding excessive heat on top of that is asking for trouble. Minimize your use of flat irons, curling irons, and blow dryers. When you do use heat tools, always—and I mean always—apply a heat protectant first. Set tools to the lowest effective temperature rather than cranking them up to maximum heat.
Air drying is your friend. After washing, apply your leave-in conditioner and oil, then let your hair dry naturally or under a hooded dryer on a cool setting. This gentler approach prevents heat damage and helps your hair retain moisture.
Get Regular Trims
Schedule a trim or “dusting” (a tiny trim of just a millimeter or two) every time you get a touch-up, roughly every six to eight weeks. This prevents split ends from traveling up the hair shaft and causing more damage. If your ends are already split, get a good haircut to remove them, then maintain your hair with regular dustings.
Handle Your Hair Gently
Treat your relaxed hair like the delicate fabric it is. Detangle only when your hair is moisturized, using a wide-tooth comb and working in small sections from ends to roots. Never rip through tangles or use harsh brushing motions. Be patient and gentle.
Avoid tight hairstyles that pull on your scalp and hairline. Edges are particularly vulnerable with relaxed hair, and constant tension can cause traction alopecia (hair loss from pulling). Opt for loose protective styles like low buns, gentle braids, or simple updos that don’t stress your hair.
Protect Your Hair at Night
Cotton pillowcases absorb moisture from your hair and cause friction that leads to breakage. Switch to a silk or satin pillowcase, or wrap your hair in a silk or satin bonnet before bed. This single change can make a dramatic difference in your hair’s health and moisture retention.
Stick to a Touch-Up Schedule
Space out your relaxer touch-ups every six to twelve weeks, depending on how fast your hair grows. You need at least half an inch to an inch of new growth before it’s safe to relax again, or you risk overlapping relaxer onto already-relaxed hair. When you do get touch-ups, make sure your stylist only applies relaxer to the new growth, not your entire head.
Consider getting a post-relaxer treatment two to three weeks after your relaxer service. These treatments, whether moisture-based or protein-based, help strengthen your hair and ensure healthy root growth.
Natural Hair vs. Relaxed Hair: Understanding the Differences
The debate between natural and relaxed hair has been going on for over a century, and it’s not going away anytime soon. Both choices are valid, and neither is objectively “better” than the other. What matters is what works for your lifestyle, preferences, and hair goals.
Natural hair that’s well cared for is structurally stronger and healthier than relaxed hair because its protein bonds remain intact. It has better elasticity, which helps it fight breakage when stretched or manipulated. Natural hair also tends to have more volume, body, and bounce than relaxed hair, and it offers incredible versatility—you can wear it curly one day and straight the next (assuming you haven’t caused heat damage).
However, natural hair comes with its own challenges. Shrinkage can make your hair appear much shorter than it actually is, and hair that stays in a shrunken, compacted state for too long forms knots, tangles, and single-strand knots. Detangling natural hair, especially dense or long natural hair, can be time-consuming and lead to breakage if not done carefully.
Natural hair also requires regular stretching to prevent excessive tangling, and many styles take more time to create since you often need to stretch or define your curls first. For people who wear their natural hair straight frequently, the repeated heat exposure can eventually cause heat damage that permanently alters the curl pattern.
Relaxed hair is easier to detangle and style on a daily basis. Simple styles can be created quickly without the need to stretch the hair first. There’s less risk of single-strand knots, and relaxed hair typically takes less time to wash and dry. It’s also more weather-resistant—humidity won’t cause your sleek style to puff up and frizz out.
On the flip side, relaxed hair is structurally weaker and more prone to breakage. It requires more intensive care to maintain health, including regular deep conditioning, protein treatments, and careful handling. The costs add up with professional touch-ups every couple of months, and you have to be vigilant about avoiding over-processing.
Growth rate is the same for both natural and relaxed hair—that’s a myth worth busting right now. Your hair grows at whatever rate your genetics and overall health determine, regardless of whether it’s natural or relaxed. The difference is that relaxed hair shows its length more obviously due to lack of shrinkage, which might create the illusion of faster growth.
Making the Decision: Is Relaxed Hair Right for You?
Choosing whether to relax your hair is deeply personal, and there’s no universal right answer. Here are the key factors to consider before making your decision.
Your hair’s current health should be your first consideration. If your hair is already damaged, thinning, breaking, or bleached, a relaxer will only make things worse. Get your hair back to a healthy state first through deep conditioning treatments, protein treatments, and regular trims. Relaxers should only be applied to strong, healthy hair.
Think honestly about your lifestyle and time commitment. Can you dedicate time to the extra care that relaxed hair requires—regular deep conditioning, moisturizing, and gentle handling? Can you afford professional touch-ups every six to eight weeks? If you’re looking for a “low-maintenance” option to avoid all hair care, relaxing isn’t the answer. It’s different maintenance, not less maintenance.
Your styling preferences matter too. If you love wearing your hair in its natural curly state most of the time and only occasionally want it straight, relaxing might not make sense. Heat tools or temporary straightening methods would be better options. But if you genuinely prefer straight hair and find yourself straightening constantly, a relaxer might save you from cumulative heat damage.
Consider your long-term hair goals. If you want to grow your hair long, you’ll need to weigh whether the potential breakage from relaxing might hinder that goal. Many people successfully grow long, healthy relaxed hair, but it requires diligent care and maintenance.
Think about scalp sensitivity. If you have a sensitive scalp, eczema, psoriasis, or other scalp conditions, chemical relaxers might cause severe irritation or burns. Consult a dermatologist before making this decision.
Don’t ignore the health research either. While the studies aren’t conclusive, there is emerging evidence of potential health risks associated with long-term relaxer use. Consider whether these potential risks concern you enough to explore alternatives.
Finally, examine your motivations. Are you relaxing because you genuinely prefer straight hair and find it easier to manage? Or are you relaxing because you feel pressure from work environments, societal beauty standards, or other people’s opinions about your natural hair? There’s no judgment either way, but understanding your true motivations helps ensure you’ll be happy with your decision long-term.
Final Thoughts
Relaxed hair can be healthy, beautiful, and manageable when approached with knowledge, care, and commitment. It’s not the enemy of healthy hair, nor is it a betrayal of your natural texture—it’s simply a choice about how you want to wear your hair.
The biggest lesson here? You’re the only person who needs to be happy with your hair. Black women and people with textured hair have faced too much policing around hair choices for far too long. Whether you choose natural, relaxed, texturized, colored, locked, braided, or constantly changing styles, what matters is that your choice aligns with your preferences, lifestyle, and makes you feel confident.
If you decide to relax your hair, find a skilled stylist who specializes in chemical treatments and uses quality products. Don’t try this at home unless you’re truly confident in your abilities—the risks of DIY relaxing are significant. Ask questions during your consultation: Which relaxer strength is right for your texture? How often will you need touch-ups? What aftercare products do they recommend? What are the signs of over-processing you should watch for?
And remember, this decision isn’t permanent in the sense that you’re stuck with it forever. Many people transition back to natural hair after years of relaxing, and many others go back to relaxing after trying natural for a while. Your hair is yours to experiment with, change, and enjoy throughout your life.
At the end of the day, healthy hair—whether natural, relaxed, or somewhere in between—comes down to informed choices, proper care, and listening to what your hair is telling you. Pay attention to how your hair responds to products and treatments, adjust your routine as needed, and don’t be afraid to seek professional help when you need it.
Your hair journey is uniquely yours. Embrace it, learn from it, and most importantly, do what makes you feel like your most authentic, beautiful self.
