Within the manufacturing environment for womens and mens Hair Systems, the production includes a step where knots are bleached, particularly along the front hairline and at the crown. This is performed to minimize the appearance of knots (seen as “dark dots”), by camouflaging their appearance, so that the impression is that hair is growing right out of the skin. As color within the hair shaft adds heft and strength, the rest of the unit is usually not bleached, in order to prevent premature shedding, due to hair weakness.
