The Most Detailed Keratin Treatment Guide

It is every woman’s dream to have silky-soft hair. But harsh salon procedures can take the life out of it and rarely do we have any control over the environmental damage that affects almost every hair type, resulting in dull and lacklustre hair. And undeniably some of us are just born with very frizzy and unmanageable hair. For this reason, more and more women are flocking to the salons for their dose of keratin treatment. So, let us help you understand everything that is there to know about keratin treatments. Check our top 4 favorites and find out which one is for your hair type!

What Is Keratin Treatment

Keratin is a protein already found in your hair. Keratin treatment is built of this natural protein, a mix of conditioners and, in the majority of cases, formaldehyde. It is one of the hottest and leading salon straightening procedures for semi-permanent silky smooth hair. This therapy has gained popularity due to its anti-frizz effect and conditioning benefits, the ability to turn dull and damaged hair into soft, supple and bouncy locks.

And all this without altering the structure of your hair, i.e. without breaking the natural hair bonds, which makes it a great alternative to relaxers. If for example, you have curly hair, professional keratin treatment will soften your natural curls into baby soft, extremely manageable twirlies so much that you could head out without even having to style it with any hair products!

At the same time, keratin treatments with a higher concentration of Formaldehyde can give smoother, straighter results. See the before and after pics below.

Difference Between Keratin Hair Smoothing and Japanese Straightening Treatment

Japanese straightening gives hair a permanent pin-straight and flat look. Keratin treatments gradually wash out, allowing the natural hair to emerge. While the keratin treatment washes out over time, Japanese straightening treatments demand a lot of upkeep to maintain the effect. Therefore, keratin doesn’t last as long as Japanese straightening, but it also doesn’t interfere with the grow-out phase. Both treatments use a very high heat flat iron to close the product in the hair fibers.

Anyway, it is always a good idea to get a pro consultation on the elasticity and porosity, texture, density and curl pattern of your hair. After that you will be recommended to use a keratin or Japanese straightener.


Is Keratin Good or Bad for Your Hair: Pros and Cons

Lately a lot of people have been raising concerns about this smoothing procedure, wondering if keratin treatment is safe or not, does keratin damage hair or, on the contrary, heal it. Moreover, is it worth its money or it is just one more trendy buzzword? We have taken a closer look at the pros and cons so you can better decide if it is a right choice for you.


  • Hair is frizz-free, soft and manageable.
  • It cuts down the styling time so much that you could even head out without having to style.
  • The treatment can keep the hair texture intact and still give soft and smooth results.
  • It does not interfere with the grow out phase. The natural hair emerges slowly as the treatment wears off.


  • The treatment contains a chemical known as Formaldehyde. A higher concentration level of this chemical is considered unsafe by the FDA. Having said that, formaldehyde is present in most commercial products.
  • Pregnant women are advised not to use this treatment as this may affect their own and their unborn baby’s health. And this goes with any chemical procedure in which the product is absorbed by the skin.
  • The procedure involves high heat of 450 degrees which may be damaging for some hair types. This step cannot be skipped as it is a crucial step in sealing the product into the hair cuticle.
  • The results from this treatment are relatively short-term and last for a maximum of 4-5 months only.

Keratin Treatment Process

As with any complex hair procedure, it is advised not to do keratin treatment at home. It is important to visit a certified salon, as this treatment requires extreme care and meticulous application. Choose a real professional — a hair stylist with years of experience in keratin procedures (remember, keratin procedure has been in the market for over 10 years now).

The treatment involves such steps:

  1. Washing hair with a clarifying shampoo to help remove all the build-up.
  2. Blow-drying until the hair is completely dry.
  3. Applying the treatment in smaller sections throughout the hair.
  4. Letting it fully saturate for 20 minutes or so.
  5. After that hair is blow-dried for the second time.
  6. A flat iron at around 450 degrees C is used section by section to seal the product.
  7. The product is immediately washed out or after 24-72 hours after the procedure.

The entire application process takes about 2-4 hours.

How to Care for Keratin Treated Hair

On average keratin treatment lasts 3-4 months. It depends on the lifestyle and post-salon hair care. Each keratin treatment has its own set of instructions. If you wish to extend your results, you have to follow them. However, these recommendations will help you to maintain keratin treated hair in any case:

  • if the 72-hour wait is needed, do not wet hair during this time, avoid any hair accessories;
  • if hair accidentally got wet, blow-dry and slightly flat iron it on low heat;
  • wash your hair as rarely as possible, use dry shampoo on the in-between days;
  • use sulfate-free and sodium-free shampoos, ideally ones developed specially for keratin aftercare;
  • shampoo with lukewarm water, follow with a cool rinse;
  • use leave-in conditioners and masks containing keratin;
  • when you don’t shampoo, wear a shower cap to keep hair dry in the shower;
  • always use heat protectant oils or sprays when curling, flat ironing and blow-drying;
  • apply products with UV protection during warm seasons;
  • use conditioners before swimming in chlorinated or salt water (or wear a swim cap), forget about sea salt sprays;
  • avoid using coloring products at least three weeks after the treatment;
  • care for your ends — consider using hair serum;
  • do not overuse any hair products — hairsprays, mousses, gels;
  • try hot oil treatments
  • use a detangler to comb out knots gently;
  • think sleeping on a silk pillowcase;
  • re-treat timely as keratin treatments are ‘cumulative’.
