How to Bleach Wig Knots Without Ruining the Lace
I ruined my first wig doing this. The second one came out orange. By the third attempt I had it down to a system that takes 20 minutes and makes the knots nearly invisible against my skin. Here is exactly what I do now.
What you need: 20 volume creme developer, bleach powder (any drugstore brand works), a small mixing bowl, a tint brush, plastic wrap, purple shampoo, and cold water. Total cost at Sally Beauty: about $12. Do not use 30 or 40 volume developer — it will eat through the lace.
Step 1: Turn the Wig Inside Out
Flip the wig inside out so the lace underside is facing up. The knots are visible as tiny dark dots on the lace. You want the bleach to hit the knots from underneath, not from the hair side. If bleach gets on the hair, it will lighten the roots and you will have a two-tone wig. Stuff the cap with a towel or wig stand so the lace is stretched flat. A wrinkled lace bleaches unevenly.
Step 2: Mix Small Batches
Mix one scoop of bleach powder with enough 20 volume developer to make a yogurt consistency. Not runny, not paste. Runny bleach will seep through the lace onto the hair. The mixture will start losing strength after about 45 minutes, so mix only what you need. For a standard 13x6 lace front, one scoop is plenty.
Step 3: Apply Only to the Knot Area
Using a tint brush, dab the bleach mixture onto the lace where the knots are. Work in small sections. Do not paint the entire lace — you only need to cover the hairline and part area. Press the bleach into the lace with the brush tip rather than painting it on. Cover the bleached area loosely with plastic wrap. The wrap keeps the bleach from drying out, which stops it from working. Do not press the wrap down — air circulation is fine.
Step 4: The Waiting Game (Check Every 5 Minutes)
This is where I messed up the first time. The knots go from dark brown to orange to blonde. You want to stop when they hit a warm blonde — about 15-25 minutes depending on your developer and room temperature. Check by lifting a corner of the plastic wrap and wiping a small area with a damp paper towel. If the knots look like a honey blonde, you are done. If they are still dark or orange, give it 5 more minutes. Do not go past 30 minutes total. The lace will start to degrade and you will end up with holes.
Step 5: Rinse Like Your Wig Depends on It
Rinse with cold water until the water runs clear. Cold water closes the hair cuticle and stops the bleach from processing further. Then wash the entire wig with purple shampoo — this neutralizes any remaining brassiness and makes the knots look cooler-toned against your scalp. Let the purple shampoo sit for 3-5 minutes before rinsing. Condition the hair but keep conditioner off the lace.
What I wish I knew before my first attempt: The knots will look lighter when the lace is wet than when it dries. Err on the side of slightly under-bleaching. You can always go back and do it again in a week. You cannot un-bleach. Also: if your wig already came "pre-bleached" from UNice or Ashimary, you probably do not need to do this at all. This tutorial is for budget Amazon wigs and unbleached lace fronts where the knots are visible as black dots against the hairline.
