Check a small section of the hair extensions every 5 to 10 minutes during the processing time.
Be sure to reapply the color with your color brush after checking, and remember that hair color when wet appears darker than dry hair color.

When you are sure that your extensions are rinsed properly, lay a towel down on your workspace. Apply a leave-in natural conditioner to each section of your extensions and comb with your wide tooth comb. Lay the extensions out and allow them to air-dry thoroughly before using them, styling the extensions, or applying any kind of heat tools.
