Here's how you can have perfectly bleached knots at home.
Orange Knots On Wig Cap
First, test a piece of hair. Most people cut their lace wig in some way before wearing them. Make sure that you save a couple of these hair clippings to do a bleach test. After mixing in your powder bleach and cream developer, apply some of it on to the piece of hair. For dark hair (1B to a color 3) allow it to sit for about 45 minutes, heating up the piece of hair with a blow dryer. Rinse the hair, let it air-dry, and observe it. The hair should be somewhat bleached – if it is slightly too dark for your scalp color, then increase processing time by 15 minutes. For example, once you apply the bleach on the underside of the lace wig or men's toupee, instead of allowing it to sit on the hair for 45 minutes, you will now apply it for an hour. If you find that the hair is a stark white, then it is over bleached. Over bleached hair knots will cause premature shedding over time. Reduce processing time for about 15 minutes.
After completing the RIT dye and allowing your system to air dry, you can go ahead and start the actual bleaching process. You will find that your once stubborn knots will now bleach seamlessly.
