Waxing hair removal uses a resin-based wax like product to remove the entire hair follicle from the root. Results can last up to six weeks.
Waxing works by spreading a warm wax mixture is spread over hair in the direction of its growth and a paper or cloth strip is then placed on top of soft wax. Hard wax doesn't require a strip because it cools solid enough, and becomes a strip in itself. Cold wax is usually already applied to pre-made strips, but a little friction over it helps generate some heat for wax to soften and better adhere to the hair.
Once wax has slightly cooled or has grasped enough to the hair, it’s pulled off in the opposite direction of hair growth. The entire hair follicle should be removed from the root, if the waxing is done correctly.
Overall, it can be done fairly quickly. It’s not as fast as shaving, but each hair doesn’t have to be individually removed like in tweezing. Wax can be spread over large amounts of hair, and removed all at once. For example, an esthetician experienced waxing hair can get both full legs (ankle up to bikini line) done in about an hour.
