The progressive brush of amino acids is a safer hair straightening option than the progressive brush with formaldehyde, as it has as principle the action of amino acids, which are natural components of the hair responsible for maintaining its structure and shine, for example, but which are lost over time, needing to be replaced.
Thus, this brush aims to replenish the hair's amino acids, improving the appearance and texture of the hair, being more suitable for those who want to reduce the volume and frizz and smooth the hair.
The amino acid brush lasts between 3 and 5 months depending on the type of hair and amount of washings performed per week, and the value also varies according to the salon in which it is performed and the product used, which can cost between R $ 150 and R $ 300.00.
How it is done
The progressive amino acid brush is simple and must be done by a professional in a beauty salon. The brush step-by-step is:
- Wash hair with deep cleansing shampoo; Then dry and apply the product; Dry again with the product applied to the hair and iron the flat iron; Rinse and apply a treatment cream indicated for this type of brush.
The amino acid brush is an alternative to the old progressive brush in which formaldehyde was used. In this procedure, the amino acids that make up the product reconstitute the wire structure and open the pores, allowing the flat iron to straighten the hair. As formaldehyde was used to close the threads, now other products are used that cause less damage to the hair and scalp, such as glutaraldehyde, for example.
Scratches of the amino acid brush
Although this brush is based on the functions of amino acids, the straightening is done by substances that can have the same result as formaldehyde when heated, as is the case of carbocysteine and glutaraldehyde, for example. Thus, this type of brush can also make the eyes sting, lead to a burning sensation, damage the hair and even alter the DNA of the cells and increase the risk of developing cancer.
Therefore, before carrying out any straightening procedure, it is important to know the substances that make up the product, their effects and if it is regulated by ANVISA. Know the risks of formaldehyde.
Recommendations after brushing with amino acids
After the brush with amino acids, it is recommended that the person avoid using anti-residue or deep cleansing shampoos, in addition to avoid discoloring or coloring hair in short periods and sleeping with wet hair.
