Human Hair systems are made with knots for steady security of the hairs onto the base cap. For hand tied units- when a dark hair is tied onto the base of a hair system with knot, a dark dot becomes visible on the skin, especially when the base is lace. Bleaching the knots of human hair systems is currently best known method to hide the knots, and this help to give the illusion that the hair is growing out of your scalp.
Lace can not hide the knots in the same way a monofilament base does. Bleaching or ‘lightening’ the knots reduces the visibility of these knots to the lace. Knots are most visible on darker colored units such as black, off black or brown hair colors. Bleached knots are not necessary for hair of lighter colors, especially colors in the blonde series.

We recommend bleached knots in about ¼ - ½ inch front. Women’s hair systems are typically made of long hair, which is often manipulated with fingers, combs or brushes. Bleaching the knots on the entire unit leads to premature, and sometimes excessive shedding because the bleached knots are weaker.

The bleached knots can also be bleached in an area of the unit that is poly coated. Depending on hair color, the bleached knots will be light brown or blonde.
