While peeling your hair system off from the back, you can gradually spray or dab adhesive remover between the bottom of the base and your scalp. This will help break down the adhesive and make the unit easier to peel off.
Using a spray remover?
Spray a light mist directly between the base and your scalp while peeling up the unit, after a few inches, stop and spray more adhesive remover.
Using a dab-on remover?
Either use the dab-on applicator or soak a liberal amount of adhesive remover on the tip of a paper towel. While peeling up the unit, swipe the applicator or paper towel across the bottom at the point where it is attached to your scalp.
No matter which method you choose, simply continue a few inches at a time until your hair system is completely off.
