According to Hollywoodhairandwigs.com...
Even the best units on earth like ours, can become tangled if they are not given the proper care. If your unit gets old or becomes tangled or puffy, you can make it look like new again with a bleach bath. The bleach acts as a clarifier and the ammonia acts as a softener to bring your unit’s hair back to life. Use the chemicals on the hair, not on the lace cap and follow the directions exactly. This treatment can be done as often as needed at your discretion.
Totally de-tangle the unit first. Just dip in the hair, not the lace cap.
1. Mix one gallon of very hot water (hottest available from the tap) with 1/4 cup of Clorox bleach. (Do not use old Clorox or a generic brand, it will not work.)
2. Totally submerge the human hair into the water for approximately 2 or 3 minutes. (Do not leave longer than 3 minutes) Comb or brush very gently when submerged.
3. Remove hair and submerge in a basin of lukewarm water that has been pre-mixed with shampoo. Gently lift in and out for about 3 minutes and also brush or comb the hair very gently when submerged. Remove and blot dry
4. Mix 1/4 cup of ammonia to 3 cups of warm water. Dip hair in and out twice.
5. Repeat step 3
6.Apply conditioner, rinse and style.
Your wig will look brand new and be tangle free
