Here is a detailed HOW-TO, I actually just did this on some hair I have and I am truly shocked at the difference!!
BLEACH TIP TO DETANGLE YOUR UNIT
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 won’t work)
2. Totally submerge the human hair unit into the water for approximately 2 or 3 minutes.Do not leave longer than 3 minutes*Small bubbles will normally appear durring the process. Comb or brush very gently when submerged.
3. Remove hair*unit and submerge in a basin of luke warm 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 unit in and out twice.
5. Repeat step 3
6.Apply conditioner, rinse and style.
Your hair will look brand new and be tangle free
The bleach method not to be used that often because it will eventually change the hair color, also you can saturate the unit with nexxus or a deep conditioner on the unit place in a plastic bag, nuke in the microwave for 30 seconds, and then put back in again for another 15 seconds.
