The amino acid progressive brush is a safer hair straightening option than the formaldehyde progressive brush, as its principle is 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 and need to be replaced.
Therefore, 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 volume and frizz and straighten their hair.
The amino acid brush lasts between 3 and 5 months depending on the type of hair and the number of washes carried out per week, and the price also varies according to the salon in which it is carried out and the product used, and can cost between R$150 and R$300.00.
How it is made
The progressive amino acid brush is simple and should be done by a professional in a beauty salon. The brush step-by-step is:
- Wash your hair with deep cleansing shampoo;
- Then, dry and apply the product;
- Dry again with the product applied to your hair and use a straightener;
- 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 structure of the hair and open the pores, allowing the straightener to straighten the hair. As formaldehyde was used to close the hair, other products are now used that cause less damage to the hair and scalp, such as glutaraldehyde, for example.
Risks of the amino acid brush
Although this brush is based on the functions of amino acids, straightening is done using substances that can have the same result as formaldehyde when heated, as is the case with carbocysteine and glutaraldehyde, for example. Thus, this type of brush can also burn your eyes, lead to a burning sensation, damage your hair and even alter the DNA of your 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, its effects and whether it is regulated by ANVISA. Find out what the risks of formaldehyde are.
Recommendations after brushing with amino acids
After brushing with amino acids, it is recommended that the person avoid using anti-residue or deep cleansing shampoos, in addition to avoiding bleaching or dyeing their hair for short periods and sleeping with wet hair.
It is important to moisturize regularly, at least once a week, so that the hair remains shiny and soft. However, it is not recommended to use products that promote deep hydration, as this will also make the effect of the brush shorter. Find out the best mask to hydrate your hair.
Who shouldn’t do
This type of brush is not recommended for those with very sensitive scalps, very oily or porous hair. Furthermore, people who have virgin hair, that is, who have never had straightening procedures or dyed their hair, may have a slightly different result than expected, and should perform the procedure more frequently so that their hair remains straight.
The amino acid brush has no contraindication for pregnant women, however, it is important that the woman has permission from her obstetrician to carry out this procedure.
