The progressive brush of amino acids is a safer hair straightening option than the progressive brush with formaldehyde, as it has as a principle the action of amino acids, which are natural components of hair responsible for maintaining its structure and brightness, for example, but that are lost over time, needing to be replenished.
So, this brush aims to replenish the amino acids of the hair, improving the appearance and texture of the hair, being more indicated for those who want to reduce the volume and frizz and smooth the wires.
The amino acid brush lasts between 3 and 5 months depending on the type of hair and the amount of washes performed per week, and the value also varies according to the room where it is made and the product used, and can cost between R $ 150 and R $ 300.00.
How is it done?
The progressive brush of amino acids is simple and should be done by a professional at a beauty salon. The step-by-step brush is:
- Wash hair with deep cleansing shampoo;
- Then dry and apply the product;
- Dry again with the product applied to the hair and pass the iron;
- Rinse and apply a suitable treatment cream for this type of brush.
The amino acid brush is an alternative to the old progressive brush in which formalin was used. In this procedure, the amino acids that constitute the product reconstitute the structure of the yarn and open the pores, allowing the plaque to smooth the hair. As formaldehyde was used to close the strands, other products are now used which cause less damage to the hair and scalp, such as glutaraldehyde.
Risks of the amino acid brush
Although this brush is based on the functions of the amino acids, the smoothing takes place by substances that can have the same result as the formaldehyde when heated, as is the case of carbocisteína and glutaraldeído, for example. So this type of brush can also leave the eyes burning, lead to the burning sensation, damage the hair and even change the DNA of the cells and increase the risk of cancer.
Therefore, before performing any straightening procedure it is important to know the substances that constitute the product, its effects and if it is regulated by ANVISA. Learn about the risks of formaldehyde.
Recommendations after brushing with amino acids
After brushing with amino acids, it is recommended that the person avoid using anti-waste shampoos or deep cleansing, in addition to avoid discolor or paint the hair in short periods and sleep with wet hair.
It is important that hydrates are made regularly, at least once a week, so the wires remain shiny and soft. However, it is not recommended to use products that promote deep hydration, as it will also make the brush effect shorter. Find out the best mask to moisturize your hair.
Who should not do
This type of brush is not recommended for those who have very sensitive scalp, very oily or porous hair. In addition, people who have virgin hair, that is, they have never smoothed or dyed hair, may have a slightly different result than expected, and should perform the procedure more often so that the hair is smooth.
The amino acid brush has no contraindication for pregnant women, however, it is important that the woman is authorized by the obstetrician to perform this procedure.
