Step 1: Turn either your frontal, closure or lace wig inside out and pin it down to a foam head. Note: if the closure has baby hairs, you should use clips to pin them to make sure they are out of the way.
Step 2: Mix equal parts bleach powder and professional developer in a mixing bowl.
Step 3: Gently dab the bleach onto the lace with your mixing brush. The bleach mixture will leak through and bleach the hair if you put too much pressure onto the lace with the brush. In order to ensure you are bleaching all of the knots, you have to make sure you apply enough bleach to the lace.
Step 4: Keep the bleach on until the knots on the closure aren’t noticeable anymore. Wait until the knots turn a honey blonde color, and then rinse the bleach out.
Step 5: Rinse the closure upside down quickly. Next, wash it with a neutralizing shampoo to stop the chemical processing. Leave shampoo on closure for 5 to 10 minutes. And then, rinse out. After that, condition your closure to keep it from getting dried out.
