Permanent Hair Straightening

Permanent hair straightening treatments are a form of chemical processing for your hair. Depending on what method of processing you use, hair that’s naturally curly or textured can be altered to lay flat and lose its curl.

These treatments work for several months or more, usually lasting until new hair grows in to replace the hair that was treated. For this reason, these processes are called permanent hair straightening.

The “permanent hair straightening” label can be used to refer to keratin treatments, thermal straightening, and “perm” straightening processes. If you find your wavy or curly hair hard to style or just want a change in your look, these processes can be appealing.

Self at-home treatments and salon treatments are both popular options. This article will help you be informed about the pros and cons of this kind of hair treatment.

Types of treatments

There are several types of treatments that claim to make your hair straighter. Each relies on a different chemical formula and processing method. Some of these treatments are sold in kits that you can do yourself at home, while others require salon-grade equipment to be done effectively.

Professional permanent straightening

A perm refers to a chemical process that permanently alters the hair follicle. Perms are sometimes associated with creating curls in hair that doesn’t naturally have it, but they can be used to make hair straight, too.

Perms are usually done in one appointment that takes a few hours. The cost of a perm can vary according to your salon and how long your hair is. Typically, prices start around $50.

At-home perms

Chemical relaxant kits can be purchased at pharmacies and beauty supply stores. These treatments claim to offer the same results as a perm from a salon. Unless you have formal cosmetology training, it will be tricky to use these kits effectively. At-home perm options tend to start around $15.

Semi-permanent hair straightening

Keratin hair treatments, Brazilian blowouts, and semi-permanent hair straightening all refer to a method of treating your hair for a straight texture that lasts 3 to 5 months. This method can take multiple salon appointments to finish application, and typically costs over $150.

Thermal straightening

Japanese thermal hair straightening, also called an acid perm, is more similar to a traditional “straight” perm than it is to a keratin treatment.

This process might involve the longest time spent in a salon chair (5 to 6 hours), but it also claims to last the longest (up to 6 months). It also costs the most, ranging from $200 to $800.

How it works

All permanent hair straightening methods use the same strategy.

A chemical solution is applied to your hair. These chemicals change the way that the proteins in your hair are configured.

With perms and thermal straightening procedures, a neutralizer is then applied to your hair. This neutralizer causes your hair to lock into its new shape, with new bonds forming between the protein molecules of your hair.

It can take several hours to infuse the hair with the chemical solution, apply the neutralizer, and style your hair. These chemical solutions often carry strong scents, and in many cases you’re cautioned against getting your hair wet or even sweating too much in the days following the treatment.

This means that you’re walking around inhaling the chemicals used to treat your hair, as well as exposing everyone near you to them.

Side effects

Hair breakage after a permanent hair straightening treatment is somewhat common. The chemical solution works by, in essence, damaging your hair so it lies flat or releases its natural curl.

This means that your hair may be harder to style and take longer to dry until it grows out and new, untreated hair takes its place.

There’s also a concern about the chemicals used for these straightening processes.

Formaldehyde, which is in almost all straightening solutions, is a known carcinogen. Applying it to your hair and inhaling fumes causes exposure strong enough to cause side effects. These may include respiratory difficulties, irritation to your nose and eyes, and skin redness and irritation.

What about natural products?

Even “all-natural” or “formaldehyde-free” formulas of hair straighteners are often full of duplicate chemicals that become formaldehyde when they’re heated.

A 2014 study on Brazilian keratin hair straightening treatments found formaldehyde levels that were deemed high enough to pose a health hazard for consumers.

Of course, it’s better for your health to look for low-exposure options, but this is a case where reading the labels and asking questions won’t necessarily yield the truth about the product you’re using.

According to the Environmental Working Group, chemical straighteners that are lye-free or alkaline sulfite-based are safer than some alternatives. Of course, the safest option of all is to avoid exposure to harmful chemicals that can absorb through your scalp and your nasal passages.

You shouldn’t get any of these permanent straightening treatments if you’re pregnant or trying to become pregnant.

Pros and cons

The pros and cons of each hair straightening depend on what method you’re considering.

Permanent hair straightening

Pros of permanent hair straightening

  • Permanent straightening at the salon is the cheapest of the salon options for getting results, and the least time-consuming.
  • It lasts for up to 6 months, and as untreated hair grows in, the weight of the treated hair beneath it can mean it grows in looking like soft waves.

Cons of permanent hair straightening

  • Perms work by damaging your hair follicles so they can’t hold their natural shape.
  • Split ends, breakage, and hair loss can occur. You’re also exposing your body to harmful chemicals during the perm process.
  • After getting a perm, you can’t color-treat or otherwise modify your hair, and you won’t be able to wear it curly, even if you want to.

At-home perms

Pros of at-home perms

  • DIY hair-straightening kits you can get at the pharmacy are affordable.
  • They claim to be simple to use.
  • They don’t require hours spent in a salon chair, and the chemicals are approved for home use, which means they may be less concentrated.

Cons of at-home perms

  • For the most part, you’re not going to get salon results with a home straightening solution.
  • You could damage your hair, to the same extent or a greater extent than you would if you went to a stylist.
  • Some consumers have reported that home hair straightening kits don’t last for more than a single wash.

Keratin treatments

Pros of keratin treatments

  • Keratin treatments claim to condition your hair, and the result from the keratin treatment is softer and smoother than other treatments that make hair feel “fried.”
  • These treatments last for 4 to 6 months, which is a significant amount of time.

Cons of keratin treatments

  • Keratin treatments don’t leave your hair pin-straight, only less curly or wavy than it was before.
  • Keratin treatments are semi-permanent, meaning that after a few months, the results start to wash out.
  • Your hair won’t return to its natural state, and you might not like the look of how new hair growth looks at the crown of your head.
  • Most of these treatments also contain harmful chemicals, even if they claim to be free of them.

Thermal straightening

Pros of thermal straightening

  • Japanese hair straightening claims to leave your hair pin-straight and easy to maintain.
  • Many people love the sleek and simple look of hair that hangs straight down without any additional maintenance required.
  • Results are long-lasting, with hair typically staying straight until new hair growth appears.

Cons of thermal straightening

  • This method of hair straightening does damage to your hair just like other options. It also consists of dangerous chemicals that you’re breathing in and absorbing through your skin.
  • Thermal straightening is quite expensive and takes hours to complete the process.
  • Once your hair starts to grow back, there’s often a stark contrast between the hair that’s been treated and your natural hair at the root.
  • People who get this kind of hair straightening sometimes find it difficult to stop, and need touch-ups several times a year.

How long does it last

Semi-permanent hair straightening lasts 3 to 4 months before your natural hair texture starts to reappear.

Home hair straightening kits don’t often last longer than 6 weeks.

Permanent hair straightening done in a salon lasts anywhere from 4 to 6 months. Once your roots start to grow in, you’ll need to decide if you’re going to repeat the treatment or wait for it to grow out.

The bottom line

Permanent hair straightening refers to treatments that will make your hair straight beyond a wash or two. Beyond that vague definition, your results will vary widely according to your hair type, how quickly it grows, and the chemical method you use to straighten your hair.

Keep in mind that “permanent” doesn’t mean forever — it just refers to the duration of one life cycle of your hair. Speak to your hairstylist about your options, and what they think might be the best one for you.

How to Straighten Your Hair Without Heat

Getting your hair to look sleek, straight, and healthy can feel like solving a difficult math equation. Using hot styling tools to straighten hair strips your hair of moisture, causing breakage. Over time, blow-dryers, ceramic straighteners, and hot curling irons can cause damage that makes even the most carefully styled hair look dry and coarse.

Tips for getting straight hair without using heat

There are tricks you can try to get straight hair without frying or burning your hair with heat. Most of these tricks will work better for people with finer hair that carries a bit of a wave.

For other hair textures, it’ll be more challenging to achieve the look of straight hair without sacrificing your hair’s health. But, if you’re willing to embrace hair with a slight curl or a little bounce, you might have more options. Consider incorporating some of the tips below into your own straight-hair solution. Keep trying different combinations of the tricks we’ve listed until you achieve a look you love.

1. Blow dry with cold air

If you’ve already mastered straight and sleek hair via the classic “blowout,” you might consider switching up your method slightly with blasts of cool air, instead. After you’ve let your hair air-dry about three-quarters of the way, divide your hair into sections as you normally would. Use the “cool” setting on your blow-dryer, making sure that your blow-dryer is moving continuously from root to tip. Keep the blow-dryer about six inches away from your hair while you dry it.

This method shouldn’t take considerably longer, but you may need to keep a straightening serum or spray-on leave-in-conditioner at the ready to tame fly-away strands. While using a hot blow dryer has been shownTrusted Source to damage the hair shaft, using cool air has been proven trusted Source to cause less damage than air drying alone.

2. Wrap your hair

Hair wrapping is one of the more popular ways to get straight hair without heat styling, but not everyone knows how to do it effectively. Luckily there are tons of hair wrapping tutorials on YouTube geared toward almost every hair type.

While there are different methods for different hair textures and lengths, the basics are pretty much the same. You’ll need “long” bobby pins (three inches in length, also called roller pins), as well as a satin “hair wrapping” scarf or turban.

To wrap hair, separate the top section where you part your hair and use a fine-toothed comb to comb it out flat. Holding hair taut, bring the hair around to the opposite side of your head from where it naturally falls and pin it tightly to the side of your head. You’ll need to repeat this method for each section of your hair, and secure with a hair turban before you go to sleep at night.

3. Roll with plastic rollers

If you buy plastic rollers in a “jumbo” (1 3/4 diameter or bigger) size, you can achieve hair that’s slightly wavy with tons of volume and a glossy finish, no heat required. Simply divide your damp hair into medium sections and roll the products into your hair before you go to bed, or about four hours before you intend to take them out. These types of rollers may take some practice, but some people with medium-to-longer length hair swear by them. Some YouTube tutorials can help you get the idea.

4. Use products meant to straighten hair

There are shampoos, conditioners, leave-in conditioning products, hairsprays, and just about everything else you can think of that are aimed at calming and relaxing your hair. Experimenting with products that are meant for straight hair, or meant to make your hair easier to style, could be a good place to start.

Smoothing serums and keratin-packed spray-on conditioners can coat your hair strands, weighing them down and relaxing your curls.

5. Sleep with your hair wet

If it’s difficult to imagine sleeping with a hair wrap or big rollers on your head, start small and simple: Try sleeping with your hair wet. Use a hairband to tie a loose ponytail at the top of your head, then create a bun shape by wrapping your hair around that ponytail and securing it with another hair tie.

If you’re sleeping with wet hair, you may want to consider getting a satin pillowcase. This will cut down on friction against your hair that can happen while you sleep, giving your hair a straighter appearance once you let it loose in the morning.

6. Try a hair mask

You can deep-condition your hair with a DIY hair mask to give it a shinier and straighter appearance. Hair masks that are meant to restore protein to hair could make curly hair appear more relaxed. Try a hair mask that uses raw egg, manuka honey, or avocado for a deep-conditioning effect. You can also use warmed coconut oil or almond oil as hot-oil treatments to infuse and strengthen curly hair.

7. Apply essential oils

Anecdotally, there are some essential oils that make hair appear tamer. Some essential oils are more readily absorbed into your hair than chemical products. Coconut oil, argan oil, almond oil, and macadamia oil can all penetrate your hair follicles, sealing and repairing the cells inside.

Once you’ve used rollers, wrapping, a cold blow-dry or another technique to style your hair, apply your essential oil of choice. Warming the oil by rubbing it between your palms may make it easier to spread the oil through your hair evenly. Focus on the ends of your hair, and be careful not to apply more than a dime-sized amount. Not only does this add a sweet scent and a beautiful gloss to your hair, it will also weigh your hair down slightly, helping it to hold its style.https://c2ad7846ecd3a8df7782df09538c17a7.safeframe.googlesyndication.com/safeframe/1-0-38/html/container.html

The bottom line

Getting hair that looks straight, gorgeous, and healthy doesn’t have to be mission impossible. While no two hair textures are exactly alike, experimenting with different ways to get your hair looking glossier and straighter can be a fun way of getting to know yourself better. If these tricks don’t work, you may want to speak to a professional hair-stylist about hairstyles and salon treatments that will give you a sleek look without heat damage.

Curly hair is influenced by the result of your genetics, your hair style, the products you use, and even how long your hair is. As you age, your hair can become less curly due to hair loss (alopecia) or get even curlier due to hormonal changes.

Styling your hair a certain way every day can “train” your hair to fall in a certain pattern, but overdoing it can actually lead to hair loss and damage. You may want to rock your natural curls once in a while and embrace the way your hair grows. Be realistic with how you envision your hairstyle looking, and be kind to yourself, too — curly, natural hair has a distinct beauty that many people appreciate.
