How Much Does a Keratin Treatment Cost? (+How Long It Lasts)

When sitting in the salon chair, have you ever been curious about the keratin treatment the woman beside you was receiving? Have you wondered about what you might expect to pay for this treatment? We’ve gathered some much-needed details on how much a keratin treatment costs. 

Here’s what you should know about how much it costs to receive a keratin treatment at the salon. Keratin treatments can be a costly service but worth the investment, depending on your type of hair texture. 

When getting a keratin treatment at the salon, you can expect to pay anywhere from $80 to $400. Factors such as the kind of treatment, location, stylist experience, and hair length help determine the cost. Lastly, you should wash your hair less often, use high-quality hair products, and avoid heat to help results last. 

What is a Keratin Treatment?

When speaking about keratin treatments, you’ll be surprised how many women don’t know what this treatment involves. Keratin treatments smooth your hair by softening curls and reducing frizz, which will make heat styling a smoother and easier process.

As long as the treatment includes keratin, professional salons can place them into the same category as Brazilian blowouts, Keratin Complex, among others. The problem is that these different formulas don’t affect hair equally.

Keratin treatments containing formaldehyde typically straighten your hair, while treatments without will smooth your hair.

What Factors Affect the Cost of a Keratin Treatment

The type of hair salon you visit, the type of treatment, and the length of your hair all factor in determining the final cost of a keratin treatment.

  • Kind of treatment – Since every treatment has its specific formula and process, the type of treatments and products a salon uses might vary, as some professional salons even have their treatments.
  • Location – The location of your salon, the cost of living, and the current demands also play a factor.
  • Stylist Experience – If your hair stylist has more experience, you can expect to pay more for keratin treatments.
  • Hair length – Hair longer will need more time to work on, so the longer your hair, the more you’ll pay in costs.

It’s important to note that everyone responds to keratin treatments differently, so there’s no way to be sure of the final results. However, it is possible for you and the salon stylist to make an estimate based on your desired wants of the treatment and the final results of clients with similar hair textures.

How Long Will My Keratin Treatment Last?

When applied correctly, Keratin treatments will last anywhere from one to six months if you properly maintain your hair. Keratin treatments aren’t meant to be permanent, and eventually, your natural hair texture will return.

Since keratin treatments are applied to the top of your hair, they will eventually wash out over time. Unlike other hair treatments, you won’t see any root growth. Depending on the formula used, you should wait at least four to six months before getting another keratin treatment because your hair can weaken, and too much formaldehyde is terrible for your overall health.

How Can I Make My Treatments Last Longer?

To make your keratin treatments last longer, you can reduce your exposure to humidity, limit how much you style your hair, and don’t wash your hair for a few days after your appointment. You should also keep your hair well-moisturized and free from toxic chemicals.

After your appointment, for the first few days, you should avoid:

  • Getting your hair wet or washing your hair
  • Using hair care products
  • Hair styling

When we say hair styling, this even includes using hair clips. If you do these styling techniques, you can create dents in your hair, which will shorten the results of your treatment. Once you’ve passed the first few days, keep these pointers in mind when maintaining your hair.

Wash Your Hair Less Often

After receiving your keratin treatment, you should avoid washing your hair as much as possible. Each time you wash your hair, you’re stripping more of the keratin layer. If you strip the keratin layer, your hair will return to its normal state sooner than expected.

If washing your hair, you shouldn’t wash your hair more than two to three times a week. With some people, this may seem like a difficult task, primarily if your hair produces more oils than others. If you have natural greasy hair, you can research which dry shampoos are allowed to use in the meantime.

Use High-Quality Hair Care Products 

After receiving your keratin treatment, you should keep an eye on which hair care products you’re using, as some lower-quality hair care products can eat away at the keratin, leaving you with unsatisfied and uneven results. Some hair care products will even make your hair appear greasy.

When picking your hair care products, you should stick with high-quality products that have a gentle ingredients list. Some ingredients to avoid in your hair care products include alcohol, sulfate, and parabens.

Avoid Tools With Heat

When using tools with high temperatures, you’ll run into the risk of melting your keratin treatment, so make sure you avoid using heat as much as possible. The upside is since keratin treatments make your hair dry faster, you won’t need to use styling tools as often.

However, if you must use styling tools, make sure you keep the temperature under 370 degrees and use a heat protectant before using the tool.

Use Microfiber Towels

After receiving a keratin treatment, you’ll want to ensure you keep the strands of your hair smooth from the coating treatment. Unknown to many, drying your hair by using a towel can also damage your hair because they’re coarse and cause breakage.

If you do need to dry your hair with a towel, you should consider using a microfiber towel since it creates less friction and is gentler on hair.

Additional Tips to Consider When Getting a Keratin Treatment

As with all other hair treatments, it’s essential to consult a professional stylist who is trained and can perform keratin treatments to give the maximum results. This is particularly important if you have damaged hair. If you have bleached hair, this will require your stylist to use a gentler product and low heat.

Since keratin treatments have formaldehyde included in the ingredients, it’s strongly advised that pregnant women avoid these treatments. When receiving a keratin treatment, your salon should have proper ventilation to avoid inhaling too much chemicals.

Pros & Cons of a Keratin Treatment

When visiting a salon, you quickly find that keratin treatments are one of their pricier services, but you won’t know whether or not they’re worth it if you’ve never received one. Here are some of the pros and cons of receiving a keratin treatment:


  • They will give you stronger hair and coat your strands in protein.
  • They save time and increase shine and texture, making your hair more manageable and easier to style, cutting drying time in half.
  • They will make your hair frizz and humidity-proof by creating a protective layer.
  • They will help retain your color by sealing dye pigments into your color, which will help reduce fading.


  • They are challenging to maintain as you’ll need to adjust your hair care routine and be more careful about what you do during the day.
  • They are expensive but are riskier if attempted at home.
  • They could put your health at risk because they contain ingredients like formaldehyde, so formaldehyde-free treatments are recommended. 

Are Keratin Treatments Worth the Investment?

Since everyone has different hairstyles, it’s hard to say whether or not a keratin treatment will work for you and if the cost will be worth it. If you’re trying to reduce frizz, increase smoothness, and be able to style your hair more manageably, keratin treatments might be worth the investment.

If you’re looking for straighter hair and a reduction in curls, you might want to opt for a different treatment. If you’re unsure if keratin treatments are suitable for you, you should consult your professional stylist. A stylist can assess your hair and come to a conclusion.
