Yes, you can change your hair texture, but the result depends on the method and your hair type

Your natural hair texture is determined by the shape of your hair follicles and the proteins in your hair shaft — you cannot permanently alter your genetics. What you can do is use chemical treatments, heat styling, or physical methods to temporarily or semi-permanently change how your hair looks and feels. Some changes last weeks or months; others wash out after a few shampoos. The most dramatic texture changes come from chemical relaxers or perms, which restructure the protein bonds in your hair, but these carry real risks of damage if applied incorrectly.

The key is understanding what each method actually does, how long it lasts, and what your hair needs to stay healthy through the process. Not every method works on every hair type, and some combinations of treatments can cause serious breakage.

Key Takeaways

  • Chemical relaxers and perms create semi-permanent texture changes by breaking and reforming protein bonds, but they require professional process and careful maintenance to avoid damage.
  • Heat styling with flat irons, blow dryers, and curling tools creates temporary texture changes that revert when your hair gets wet or you wash it.
  • Keratin treatments and similar smoothing products last a few weeks to a few months and gradually fade rather than washing out suddenly.
  • Combining multiple texture-changing methods — like relaxing and then heat styling — increases the risk of breakage and requires stronger hair care between treatments.
  • Your hair's health and thickness determine which methods are safe for you; fine or previously damaged hair may not tolerate chemical treatments.

Chemical relaxers: semi-permanent straightening

A chemical relaxer is a cream or liquid that breaks down the protein structure in your hair, allowing it to be reshaped into a straighter form. The two main types are sodium hydroxide relaxers (the strongest, used most often) and calcium hydroxide relaxers (gentler, sometimes called "no-lye" relaxers, though they still contain alkaline chemicals). A stylist applies the relaxer to your hair, leaves it on for a set time — usually 10 to 20 minutes — then rinses it out and applies a neutralizer to stop the chemical reaction.

The result is semi-permanent: your hair stays straighter until new hair grows in at the roots. You will see new texture growth within 4 to 8 weeks, which is why people with relaxed hair typically get touch-ups every 6 to 10 weeks. The main risk is over-processing — leaving the relaxer on too long or explore it to hair that has already been relaxed — which causes breakage, thinning, and sometimes hair loss. Relaxers also make your hair more fragile, so you need to use gentler shampoos, deep condition regularly, and avoid other chemical treatments like perms or color for at least two weeks.

Perms: semi-permanent curling

A perm (short for permanent wave) does the opposite of a relaxer: it breaks down protein bonds and reshapes your hair into curls or waves. The process is similar — a chemical solution is applied, left on for 15 to 30 minutes depending on your hair type and the curl size you want, then neutralized. The curl pattern lasts until new hair grows in, usually 3 to 6 months, though the curl gradually loosens over time.

Perms work best on straight or wavy hair; they are less effective on hair that is already very curly or coily. Like relaxers, perms weaken your hair and make it more prone to breakage, especially if your hair is fine, previously colored, or already damaged. You should wait at least two weeks before coloring permed hair, and you need to use moisturizing shampoos and conditioners to keep the curls from becoming frizzy or dry. If you want to straighten permed hair later, you will need a relaxer, which means your hair is being chemically treated twice — a significant stress.

Heat styling: temporary texture changes

Heat tools — flat irons, blow dryers, curling irons, and hot rollers — reshape your hair temporarily by using moisture and heat to soften the protein structure, then cooling it into a new shape. A flat iron can straighten curly hair; a curling iron can add waves to straight hair. These changes last until your hair gets wet or you wash it, at which point the moisture resets your hair to its natural texture.

Heat styling is reversible and does not require chemicals, but it does cause damage if done incorrectly or too often. High heat, especially on damp hair, can cause the water inside your hair shaft to turn to steam and rupture the hair from the inside out — this is called heat damage. To minimize risk, use a heat protectant spray before styling, keep the temperature moderate (300 to 350 degrees Fahrenheit for most hair types), and avoid styling wet hair with a flat iron. Let your hair air-dry partially first, or use a blow dryer on a lower setting. Limit heat styling to a few times a week if possible, and give your hair breaks between sessions.

Keratin treatments and smoothing products

Keratin treatments are semi-permanent smoothing products that coat your hair and fill in gaps in the outer layer, making it look smoother and shinier. They are not as strong as relaxers — they do not permanently change your hair's structure — but they do reduce frizz and make curly or wavy hair easier to manage. The treatment is applied to clean, damp hair, left on for 20 to 30 minutes, then rinsed out. Results typically last 2 to 3 months and gradually fade as you wash your hair.

Keratin treatments are gentler than chemical relaxers and perms, but some formulas contain formaldehyde or formaldehyde-releasing chemicals, which can be irritating if you have sensitive skin or respiratory issues. Look for formulas labeled formaldehyde-free if this is a concern. After a keratin treatment, you need to avoid washing your hair for 48 to 72 hours to let the product fully set, and you should use sulfate-free shampoo afterward because sulfates strip the treatment away faster.

Combining methods and the risk of damage

If you want to change your texture dramatically — for example, relaxing your hair and then adding permanent color — you are explore multiple chemical stresses to the same hair shaft. Each treatment weakens your hair a little, and the combination can cause serious breakage. Stylists typically recommend waiting at least two weeks between different chemical treatments to give your hair time to recover and to assess the damage.

If you have fine hair, hair that is already damaged, or hair that has been through multiple treatments, some methods may not be safe for you. A stylist can do a strand test — explore the chemical to a small, hidden section of hair — to see how your hair will react. If the test shows significant breakage or damage, that method is not right for your hair at that time. You may need to focus on deep conditioning and protein treatments to strengthen your hair before attempting any texture change.

Daily care to protect changed texture

Once you have changed your hair texture, keeping it healthy requires different care than your natural hair needed. Relaxed, permed, and heat-styled hair is more fragile and dries out faster, so you need to moisturize more often. Use a sulfate-free shampoo (sulfates strip moisture and fade color), condition every time you shampoo, and do a deep conditioning treatment once a week. Avoid brushing your hair when it is wet, because wet hair is more elastic and breaks more easily — use a wide-tooth comb instead.

Sleep on a silk or satin pillowcase or wrap your hair in a silk scarf, because cotton pillowcases create friction that causes breakage and frizz. If you are heat styling, use a heat protectant spray every time. Trim your hair every 6 to 8 weeks to remove split ends before they travel up the hair shaft and cause more breakage. These habits take time but make a real difference in how long your changed texture lasts and how healthy your hair stays.

Frequently Asked Questions

Can I go back to my natural texture after a relaxer?

Yes, but it takes time. Your natural texture will grow back at the roots within 4 to 8 weeks. To transition back fully, you can either cut off the relaxed hair gradually or use protective styling (braids, twists, buns) to minimize breakage as the two textures grow together. Some people use a "big chop" — cutting off all the relaxed hair at once — to start fresh.

What is the difference between a relaxer and a keratin treatment?

A relaxer permanently changes your hair's structure by breaking protein bonds; the change lasts until new hair grows in. A keratin treatment coats your hair and smooths the outer layer but does not change the structure; it gradually washes out over 2 to 3 months. Relaxers are stronger and longer-lasting but also riskier for damage.

Can I perm or relax my hair if it is already colored?

You can, but you should wait at least two weeks between the color and the chemical treatment to let your hair recover. Colored hair is already weakened, so the combination increases breakage risk. A strand test is especially important if your hair has been through multiple treatments.

How do I know if my hair is too damaged for a relaxer or perm?

Signs of damage include split ends, breakage when you brush or style, a straw-like texture, and hair that does not bounce back when stretched. If your hair shows these signs, focus on deep conditioning and protein treatments for several weeks before attempting any chemical treatment. A stylist can also do a strand test to see how your hair will react.

Will heat styling permanently change my hair texture?

No. Heat styling changes your texture temporarily — the change lasts until your hair gets wet or you wash it. However, repeated heat damage over time can cause permanent breakage and thinning, so limiting heat styling and using protection is important for long-term hair health.
