What is a Moroccan brush and how long does it last?

The Moroccan brush is a hair straightening method, created by a Moroccan company. In addition to straightening the hair, it moisturizes and leaves hair silky and shiny.

Created by a Moroccan company (reason for the name of the procedure), the effect of the brush usually lasts from 3 to 5 months on the hair depending on the type of hair.

The more curly and dry the threads are, the shorter the duration of the procedure, which will lose its effect as the washes.

Unlike the progressive brush, it is not necessary to wait 3 days to wash your hair after the procedure, this can be done even on the same day if you wish. Therefore, the treatment has conquered the public.

The product does not have a strong smell and the procedure lasts 1 hour and a half on average. In addition, there is no risk of marking the hair if you need to pin it after the brush, as it contains neutralizing actives that fix the smooth shape given to the strands.

To prolong the effect of the Moroccan brush, it is recommended to moisturize the hair monthly, use shampoo and conditioner without alcohol and without salt in the composition.

Depending on the type of yarn, it will be necessary to repeat the process to achieve the desired smooth. In this case, try to make intervals of 20 to 30 days between each application.

What is the composition of the Moroccan brush?

The Moroccan brush has in its composition keratin, aluminum, silicon, silk proteins , clay and cocoa extract. In addition, it has 0.2% formaldehyde, which is the limit allowed by the National Health Surveillance Agency (ANVISA). The brush can be used on all types of hair, including dyed ones.

In the composition it is possible to contain other ingredients, varying according to each manufacturer. Among them are argan oil, cocoa oil, collagen and others.

Moroccan brush has formaldehyde?

In general, the Moroccan brush has formaldehyde in its composition, however, in the amount allowed by Anvisa which is 0.2%, considered not harmful to health.

If you are going to perform the procedure in a beauty salon, it is important to check the product being used, to ensure that you only have the allowed amount of formaldehyde.

Some products sold in pharmacies or cosmetic stores for the homemade Moroccan brush do not have formaldehyde in their composition, as they are intended for non-professionals in the field.

Step by step

It is possible to make the Moroccan brush at home, but it is worth mentioning that it is a laborious process that has several steps.

Ideally, it should be done in a well-ventilated place, because during drying, smoke can come out during the procedure and cause burning in the eyes.

Remembering that this is just a suggestion, as each manufacturer indicates the best way to apply it on the product packaging.

To perform the procedure at home, you will need:

  • 1 Moroccan brush kit (deep cleansing shampoo + hair treatment);
  • Disposable gloves;
  • 1 fine comb or brush;
  • 1 container for pouring hair treatment;
  • Dryer;
  • Board.

Check out the procedure step by step below:


Wash your hair with warm water, using a deep cleansing shampoo (anti-residue) and conditioner.

It is recommended to pass the shampoo more than once, so that there is no impurity left on the hair that interferes with the action of the straightening product.

Rinse your hair thoroughly to remove any product residue. Then, wipe off excess moisture with a towel and dry with the dryer.

At this stage there is still no need to worry about making a brush, just dry your hair to remove moisture well.

Hair preparation

Separate the hair, dividing it into four parts: top of the head, sides and bottom of the hair, and secure them with barrettes.

Before starting to apply the product of the Moroccan brush, it is important to do a wick test to ensure that there is no adverse reaction to the product.

Product application

Start at the bottom of the hair, previously divided. Divide this part again into smaller strands.

Apply the product all the way through the locks, ensuring that the product is well spread from root to tip. This can be done with the aid of a brush or fine comb.

After applying the product to all parts of the hair, let it act for 20 minutes. It is not recommended to exceed this time.

It is also not necessary to rinse the hair at this stage of the process.

Hair straightening with hairdryer and flat iron

After the product has had a long time, dry your hair with a dryer, brushing strand by strand, from top to bottom.

After drying, flatten your hair with the flat iron at 200 ° C. This should be done with thin strands, 6 to 9 times per strand, along the entire length of the strands (from root to ends).

This step is the most important of the process, as it will define the new shape of the wires. So, look for the flat iron.

If you don’t want such a smooth effect, you can skip the board step and stop at the dryer. In this way, the treatment will only reduce the volume of the hair and align the strands.

Attention: If the hair is very damaged and elastic, it is recommended not to overdo the use of the flat iron, to avoid breaking the strands.


After completing the previous steps, it is time to rinse your hair to remove the product. At this point, it is already possible to notice the softness in the hair.

Wire sealing

As an optional step, it is possible to apply a moisturizing or sealing mask after rinsing.

In some brands, the kit already contains the product to seal the cuticles as a step to finalize the Moroccan brush.

After applying the sealant, let it act for 3 to 5 minutes and rinse the hair. Then let it dry naturally or, if you prefer, use the dryer to make the strands more aligned.
