Some lace wig wearers prefer a curly human hair lace wig to wear it curly or flat iron it to wear straight.  If you do not properly wash and care for your wig, it may tangle. A customer informed me of a method called a bleach bath to untangle human hair wigs, even when they have become matted & knotted. I tried it on one of my old wigs and it came back to life in near perfect condition.

You will need:

Bleach
Ammonia
Shampoo
Conditioner
Freezer Bag
Hot Boiling Water

• In a bowl mix 1 gallon of very hot water with ¼ cup of bleach.
• Place the wig in the bowl allowing it to soak for 2-3 minutes. Do not leave in longer than 3 minutes. Gently comb or brush while submerged.
• Rinse the wig in warm water
• In a bowl, mix ¼ cup of ammonia with 4 cups of water. Dip the wig in the mixture and rinse with warm water again.
• Put wig in a freezer bag with deep conditioner (soak/submerge it totally). Make sure the bag is tightly sealed.
• Submerge the freezer bag in the boiling water for about 10 mins. Finally wash the conditioner out and gently comb it with a wide tooth comb.

Do not use the bleach method often because it will eventually change the hair color.
