When necessary wash your unit with a sulfate-free shampoo. Otherwise co-wash.
Use a dangling brush from The Natural Way or any detangling brush and always start from the bottom and work in sections.
Air Dry your unit if possible, if not use a hooded dryer. Always use a light heat protectant to insure your extensions lasts as long as your unit construction does.
Store your unit in a satin bag when you’re not wearing it.
