This stuff is amazing at detangling tangled matted hair extension. This product can be used on your own hair as well to add shine and to protect your hair from heated styling tools. Spray very small amount on your hair before using curling iron or blow dryer. Works best on human hair but may help some for synthetic hair as well. Super easy to use. All you have to do is to spray on the tangled mass and leave it on for few minutes and comb through. This bottle will last for a long time. You only need to spray a little bit because this product does not contain any water or any types of filler ingredients.
