The brush containing bio-ceramic MIG3® smooths the hair cuticle. A big hit in the Brazilian beauty industry. It smooths the hair cuticle, and you can feel its effectiveness after just one use. With daily use for one month, you will experience healthy, natural shine. This product was created when hairdressers, who were cutting clients' hair while using BIO gloves, noticed the change in their hair and suggested making an INVEL brush. Initially, it was sold only in a limited region, but its effectiveness spread by word-of-mouth throughout Brazil, making it a huge hit.
