The definitive brush, also called the Japanese or capillary plastic brush, is a method of straightening the hair that changes the structure of the hair leaving it permanently straight.
This type of straightening is indicated for those who have curly or wavy hair and want to have their hair definitely straight without having to resort to the use of a hairdryer or straightener. This brush lasts an average of 3 to 8 months, which is the time the hair takes to grow, being necessary to touch up only the root. However, it is recommended to perform a good hydration once a week to keep the hair soft and shiny for longer.
People who make the permanent brush should not use any other chemical in their hair, not even dye, because it can result in permanent hair damage. If you want to dye, for example, you should let your hair grow and cut the part that has been chemically treated.

- Wash the hair with an anti-residue shampoo, to open the cuticles of the threads and facilitate the penetration of the product, and dry them with a towel; Apply the product strand by strand and let it act for 40 minutes or according to the indication of product; rinse hair with cold or warm water and make a brush; after brushing, flatten and shape the hair the way the person wants; apply the neutralizing product on all hair and let it act for approximately 20 minutes.
