How Much Does Permanent Hair Straightening Cost?

We all love straight and sleek tresses, but temporary hair straightening with a flat iron only lasts around 2 to 3 days. Not to mention, having to work with a blow dryer or a flat iron every other day can become quite tedious. Nobody likes that. 

So, it makes total sense to look for a permanent fix, right? But how much does permanent hair straightening cost?

Permanent hair straightening at a salon usually starts from $50 and can go all the way up to $900+ depending on the type of treatment you’re getting. In general, you can expect to spend around $550 for professional permanent straightening. 

Sure, the price range is huge but there are a lot of factors at play here. We’ll discuss everything in detail. Scroll through to learn more!

What is Permanent Hair Straightening?

A permanent hair straightening treatment is a chemical process used to smooth and straighten your hair. This treatment works by altering the structure of the strands so that your hair loses its curl pattern and lays flat.

It’s called “permanent hair straightening” because the results usually last at least a few months. You can expect your hair to remain straight until new hair grows in. 

If your curly hair is stubborn and hard to style, permanent hair straightening treatments can be exactly what you need. 

Types of Hair Straightening Treatments & Their Costs

There are several permanent hair straightening methods that you can use to straighten out your tresses. Let’s take a look at what those methods are and find out how much they cost:

TypeLow PriceAverage Price High Price
Chemical Hair Straightening$50$110$250
Keratin Treatment$150$300$600
Japanese Hair Straightening$400$625$900+

1. Chemical Hair Straightening 

Chemical hair straightening, also known as hair relaxing, is a technique that uses special types of creams and lotions (hair relaxers) to straighten your locks. Hair relaxers work by penetrating your hair shaft and causing it to lose its natural curl pattern. As a result, you get stick-straight hair without frizziness. The results usually last until your hair grows out. 

You can buy at-home chemical relaxant kits for as low as $10 online or at local pharmacies. The problem is that these at-home chemical straighteners might not be able to completely straighten your hair. And using them correctly can be tricky. 

That’s why it’s recommended that you head to a salon for hair relaxing. It costs around $110 with average prices ranging from $50 to $250. The cost varies depending on the salon, length of your hair, and the experience of the stylist. 

Salons use relaxers with powerful formulas, so you get superior results that last.

2. Keratin Hair Straightening

A keratin treatment is a semi-permanent hair straightening method that smooths your hair and eliminates frizz. You see, high porosity hair allows moisture to be absorbed into your hair, and this causes frizziness. 

Keratin treatment works by filling in the gaps in your overly porous hair where keratin has depleted. This is done using a solution containing formaldehyde. You can expect smoother and straighter hair after the treatment. Plus, it also adds shine to your hair. 

This treatment is very similar to a Brazilian blowout. Both these treatments aim to eliminate frizz and smooth your strands. 

In general, a keratin treatment would set you back around $300 USD. On average, women spend anywhere between $150 to $600. Again, the length of your hair, the location of the salon, and the experience of your stylist play an important role when it comes to the treatment cost. 

3. Japanese Hair Straightening

Japanese hair straightening, also known as thermal reconditioning, is one of the most popular hair straightening methods for curly and wavy hair. 

A special solution is applied to your locks which breaks down your hair’s bonds to soften it. Then your hair is rinsed, blow-dried, and finally flat-ironed to give you bone-straight tresses. 

This is a time-consuming process and can take 6 to 8 hours. But it also delivers long-lasting results, typically 6 to 8 months. 

Coming to its cost, Japanese hair straightening is one of the most expensive options. The prices usually start from $400 and can go up to $900+. The cost will depend on the salon as well as your stylist. 


The cost for permanent hair straightening varies a lot depending on a number of factors. But generally speaking, you can expect to pay between $50 to $900. At-home hair straightening options can be a lot cheaper, but don’t expect salon-like results. 

These treatments sure are expensive, but are they worth it? Absolutely. They can save you a lot of time and can also boost your confidence. You can choose any of the treatments you like depending on your needs.
