Our opinion:

If you are looking for a shampoo to apply after a treatment on your hair, such as smoothing or coloring,Seliar’s post-treatment keratin shampoo will be perfect. In our opinion, this is the best keratin shampoo to repair and strengthen your hair fiber after chemical treatment.
It is not aggressive to your hair (it does not contain paraben or sulphates) and makes it soft, even if you have frizzy or curly hair. We only regret the presence of Disodium Laureth Sulfosuccinate which is a derivative of sulphates.

What is keratin?

Keratin is a natural protein found in our hair fibers,and provides flexibility and elasticity, shine, and resistance. The hair fiber is 97% keratin, but it may lack it: in this case, the hair becomes brittle and fragile. This is why it is important to replenish this protective layer of our hair fiber using products, such as keratin shampoos, but also sprays or masks.

Keratin, a multifaceted protein

The hair is composed of three concentric layers of keratin. There are three types of keratin, each of which has its own specificities:

  • The cuticle: this layer of keratin acts as a protective layer. It is composed of scales welded together by the ceramide so that the hair has a smooth appearance (which gives it its shine) and that the water inside the hair does not escape. It is this layer that also absorbs water from the air to moisturize the hair;
  • The cortex: this layer is composed of fibers (macrofibrils, microfibrils, protofibrils) that, twisted together, form the hair and give it its elasticity and vigor;
  • The marrow: it has no role in the vitality of the hair because of its composition (only cells without nucleus).

Why opt for a keratin shampoo?

When your hair has been weakened,whether naturally (by prolonged exposure to the sun, by repeated bathing in seawater in the summer, etc.) or chemical (by smoothing, brushing, colouring…), this fundamental protein may be missing.
In this case, keratin shampoo is ideal for re-injecting keratin into your hair fiber. The keratin in the product coats your hair and makes it softer, brighter, and above all stronger. That’s why, even if you haven’t undergone chemical treatment but only have naturally dry, curly hair, keratin shampoo will be your everyday ally.

How do I apply a keratin shampoo?

Most keratin shampoos have the advantage of being very simple to apply: in fact, it is enough to apply them as a classic shampoo. On dry or wet hair, take a dab of shampoo on your palm, and lather it while working your hair, as evenly as possible, massaging well to penetrate the product from the scalp to the tips.
Leave to rest for a few minutes for optimal effect, then rinse well. Some shampoos will require a second application, others will not; you can also use another product as a supplement, such as a moisturizing after shampoo.

How to choose your product

What criteria should be taken into account?

You will understand: Keratin is a very important protein for the good health of your hair. So we’re not kidding with the choice of her keratin shampoo! It must be chosen according to several criteria in order to best meet your needs:

  • The frequency of use
  • The type of hair you have (texture, length)
  • The composition
  • Smell or perfume
  • The texture of shampoo
  • The budget you have

Know how to adapt your shampoo to your washing habits

It is important to choose your shampoo according to your washing habits: if you wash your hair every day, you will need to opt for a shampoo with moisturizing properties. Some keratin shampoos have other components that allow you to moisturize your hair while strengthening it, such as castor oil, argan oil, coconut oil

What are the best keratin shampoos?

A tailor-made shampoo for your hair!

In addition to your washing habits, another criterion should be taken into account as a priority when choosing your keratin shampoo: the texture of your hair.
If you have curly or frizzy hair, do not hesitate to choose products very concentrated in keratin and use them daily. (see curly hair shampoo)
If you have greasy hair(see greasy hair shampoo),on the other hand, you will have to choose softer shampoos, which do not have a greasy texture and are easy to rinse. If you have sensitive scalp, pay attention to the composition of shampoo, avoid products containing sulphate, paraben, or other aggressive chemical components; and focus on natural or even organic shampoos as much as possible.

Finally, some keratin shampoos are dedicated to people who have undergone a scan or coloring treatment, so they will be adapted to your need if you want to replenish your damaged hair fibers following chemical treatment.

A shampoo that you like for a pleasant treatment

To keep your hair under control on a daily basis, it’s also important to choose a shampoo that you like, both in its fragrance and texture (if you prefer foaming shampoos for example).


Keratin is a fundamental protein that guarantees the good health of your hair. If you miss it, your hair will be more fragile, brittle, dull. In short, keratin makes your hair strong and healthy, but also beautiful. If you want to bring your damaged hair back to life, then keratin shampoos are the perfect remedy for you!
