And, thanks to modern advancements in hair technology, there are now five popular hair straightening treatments that you can try out. But, what’s the price you pay – figuratively and literally? Which one is the safest? How long does your hair remain straight? Here’s everything you need to know about various hair straightening treatments for silky straight hair. Read on to find out all about them!

5 Hair Straightening Treatments

1. Hair Rebonding

Your hair is made of proteins bound by disulfide bonds. This gives the hair its structure – straight, wavy, curly, coily, etc. Hair rebonding breaks these bonds to relax the hair. Then, a neutralizer is applied to rebond the natural structure to make it straight and silky. This treatment takes about 3 hours, depending on your hair texture, thickness, density, and length.
Cost: $200-$600

Results Last: Up to 6 months

Safety: Hair rebonding can weaken your hair. It is not suitable for people with thinning hair.

2. Keratin Treatment (Brazilian Straightening)

Your hair is made of keratin protein. But with age and due to poor nutrition, the keratin protein content decreases, resulting in dry and dull hair. Keratin treatment, also known as Brazilian straightening, adds a coat of keratin to your hair, thereby replenishing its nutrients and leaving it soft, smooth, frizz-free, and straight. Keratin treatment can take about 1-4 hours, depending on your hair length and texture.

Cost: $200 – $500

Results Last: 2-8 months

Safety: It is a relatively safe hair straightening treatment. However, avoid frequent keratin treatments as it contains formaldehyde, which can cause hair breakage and damage if proper care is not taken post keratin treatment.

3. Chemical Straightening (Hair Relaxing)

Chemical straightening (or hair relaxing, as it is popularly known)refers to permanent hair straightening. The process is quite tricky and should be done by a well-trained professional. It involves the application of a chemical that helps break the bonds that provide your hair its structure. However, if too many bonds are broken, there’s a risk that your hair mayend up looking limp. And, if not the right number of bonds are broken, your hair might look somewhere between straight and wavy/curly.

Cost: $200 – $500

Results Last: 6-8 months

Safety: The formaldehyde in the chemical used in this straightening method is harmful and may cause hair breakage, weak hair, and hair fall. Unless you get an expensive treatment that does not contain harmful ingredients, you might end up causing some serious damage to your hair.

4. Japanese Hair Straightening

Japanese hair straightening or thermal reconditioning is also a permanent straightening treatment. It involves loosening the protein bonds and reshaping the hair structure. It takes a good 6-8 hours for this hair straightening treatment to complete. You might also need to visit the salon after a day or two for an hour or more for the final step.

Cost: $450 – $800

Results Last: 6-8 months

Safety: Japanese hair straightening can be quite damaging to the hair. If you do decide to go for it, make sure to use good products to maintain your hair and prevent hair fall. Also, avoid frequently opting for this straightening treatment.

5. Hair Botox

Hair botox is a non-chemical deep conditioning treatment. This treatment makes your hair smoother, shinier, and healthy-looking. It is an effective way to straighten your hair and make it less fussy. The ingredients in this treatment contain vitamin E, vitamin B5, collagen complex, argan oil, coconut oil, glyoxylic acid, and amino acids that replenish damaged hair without the harmful effects of other hair straightening treatments.

Cost: $100 and above

Results Last: 2-4 months

Safety: Hair botox is the safest hair straightening treatment. It does not contain formaldehyde, a potent carcinogen, and other harsh chemicals that weaken the hair.

These are the 5 hair straightening treatment options available right now. But, which one should you choose? Safest or cheapest? Let’s dig a little deeper in the following section.

Which Straightening Treatment Should You Choose?

To decide which straightening treatment should you choose, you should consider the following:

  • Your Hair Type: Do you have wavy, curly, or coily hair? Is your hair damaged? Is your hair thinning and prone to breakage? Stay away from chemical straightening and Japanese straightening if your hair is thinning, fine, and/or prone to breakage.
  • Chemical Ingredients: Chemicals are not good for your hair. But, certain ingredients like formaldehyde should be avoided at all costs. If you decide to opt for permanent hair straightening, make sure you do not get it done frequently or opt for the one that does not contain formaldehyde.
  • Your Budget: Hair straightening is costly. But, going cheap may put the health of your hair at risk. We recommend you save up if you want to opt for a straightening treatment that’s a little above your budget but is probably the best for your hair.
