What kind of shampoo can you use after a brazilian blowout ?


Following a keratin straightening, the hair needs some time to assimilate the treatment.

Certain substances present in conventional shampoos could disrupt the care process provided by Brazilian straightening,

The consequence? A bad impregnation of the care and thus a reduction of the duration of smoothing.

This is why it is recommended to use a shampoo without sulfates after a Brazilian.

I reveal here the good habits to adopt to make your keratin straightening last as long as possible.


What shampoo to use after a Brazilian straightening ?

After a Brazilian straightening, it is recommended to use a sulfate-free shampoo enriched with keratin. The keratin content of the shampoo helps prolong the effect of straightening. The absence of sulfate allows the proteins provided by the Brazilian straightening to be preserved for longer.

The care offered by a keratin straightening provides the hair with many health benefits.

Why can these benefits be ruined by using a sulfate shampoo? Find out below.

Why is a sulfate shampoo not recommended after a Brazilian straightening?

Sulfates are present in most shampoos in order to clean the hair thoroughly. They considerably increase the effectiveness of hair cleaning products.

They are very useful to fight against greasy hair and impurities. However, they can be very harmful to the hair in the long run.

One problem is that sulfate shampoos do not differentiate between good and bad oils. In the long run, their use can then dry out the hair and make the scalp more sensitive to damage.

For these reasons, it is essential to opt for a sulfate-free shampoo after a Brazilian keratin straightening. Among other things, it helps prolong the effect of straightening.

What are the benefits of a sulfate-free shampoo?

Sulfate-free shampoos enrich the hair and prolong the duration of a keratin treatment such as Brazilian straightening.

Here are some benefits of sulfate-free shampoo:

  • Facilitates quick repair of damaged hair
  • Rinses out very well with water
  • Takes care of hair and scalp
  • Does not accumulate in the body
  • Does not cause allergic reactions

That’s why the best shampoo to maintain a Brazilian straightener is a sulfate-free shampoo.

It prevents the removal of the beneficial proteins provided by the treatment, helps repair the hair, nourishes it and facilitates styling.

When choosing your shampoo for straightened hair after a Brazilian straightening, read the list of components carefully, consume only those that do not contain sulfates and enjoy smooth and shiny hair for at least 6 months!

And if you want to take your approach even further, you can also opt for a shampoo without sodium, sulfates and silicone.

Sulfate-free shampoo after a tannin smoothing is also a good choice.

Can we use dry shampoo after a Brazilian straightening?

Yes, you can use dry shampoo after a Brazilian straightening.

A treatment with keratin does not cause any contraindications for the use of dry shampoos.

Why use a dry shampoo after a Brazilian straightening?

During the 3 to 4 days following a keratin treatment, you should avoid conventional shampoos to ensure that the treatment is well absorbed by the hair.

During this short period, the hair may be a little sticky and smelly, but you cannot wash it with your usual shampoo, otherwise the treatment will be disrupted and the smoothing time will be shortened!

Dry shampoos work by absorbing excess oils and sebum from the base of your hair. This gives each strand a boost and leaves your hair clean and fresh.

With reasonable use of a few times a week, dry cleansing will help you keep your hair healthy.

Although it is recommended for use right after a keratin treatment, remember that dry shampoo should be used sparingly, it is not intended to completely replace regular shampoo.

The benefits of Brazilian straightening

Keratin hair straightening not only removes curls, but also restores hair strength.

Its application is very simple: it consists of opening the cuticle of the hair fibers and introducing keratin using a straightener.

Keratin is naturally present in the hair, this protein is essential to good hair health.

This treatment is particularly recommended for hair damaged by heat, chemicals or other factors.

When to wash the hair after a Brazilian straightening?

The waiting time before washing hair after a Brazilian straightening is on average 1 to 4 days. This time varies mainly according to the range of products for straightening used.

If the first keratin straightening treatments required a minimum of 3 days before the first wash, the current treatments often require only one or two days at most.

The risk of washing the hair too soon is that the water affects the result and duration of the straightening process.

This can be especially restrictive during the summer, when you have to take into account sweating, vacations at the sea or swimming pool trips.

Which conditioner after a Brazilian straightening?

I advise you to use a nourishing non-greasy conditioner after a Brazilian straightening. Twice a month is enough to keep your hair healthy and smooth.

Apply the conditioner to your freshly washed hair to nourish your strands with fundamental proteins that prolong the life of the keratin treatment.

Using a conditioner keeps your hair optimally moisturized and provides essential amino acids for healthy hair. This will keep your hair shiny and smooth for longer.

What product to use after a Brazilian straightening?

A dry shampoo

The dry shampoo allows to clean the hair without disturbing the straightening process. It is particularly necessary in the early stages after the Brazilian straightening.

A nourishing conditioner

Following a keratin straightening, a good conditioner provides the hair with the essential elements for its vitality. I recommend using it about twice a month to prolong the duration of the straightening.

Sun protection

Summer is obviously a good time to show off your straight hair to envious eyes!

However, prolonged exposure to UV rays could alter your straightening. To protect your hair from the sun, I recommend using a moisturizing sun care product.

You can choose between a protective spray or an oil.

To make your hair and skin more resistant to the sun, a good diet is also essential. Fruits and vegetables rich in carotenes are to be preferred, such as carrots or apricots.

What not to use after a Brazilian straightening

Keep in mind the following basic rules after a keratin treatment:

  • The use of greasy products is strongly discouraged. These can not only damage the effects of the treatment, but also damage the hair.
  • Do not use clarifying shampoos designed for deep cleansing, nor shampoos containing sodium chloride or other sulfates. In general, it’s best to avoid these substances in your hair, whether you’ve been keratin-treated or not.
  • Limit the use of the straightener. When the effects of straightening start to wear off, it can be tempting to give it a boost with a straightening iron. While this is entirely possible, be sure to limit its use as much as possible and go for the best steam flat iron for natural black hair available.

In any case, if you do your Brazilian straightening in a hair salon, don’t forget to ask your hairdresser what treatments should be avoided after the treatment.

Why not wash your hair after Brazilian straightening?

This is because it takes a few days for the hair fibers to absorb the keratin treatment. However, humidity could disrupt the assimilation of keratin in the hair cuticles.

If you wash your hair too soon, you run the risk of removing some of the keratin. This will result in a shorter straightening time.

This explains why you cannot wash your hair with your usual shampoo for at least 24 hours after the Brazilian straightening.

How to dry your hair after a Brazilian straightening?

It is best to blow dry your hair after a Brazilian straightening.

This is because the heat activates the smoothing more effectively. You will then find yourself with straight and disciplined hair. Blow-drying your hair once in a while also helps to stiffen the hair fiber and prolong the straightening process.
