Which technique is used to remove hair at the root?

Waxing is the technique used to remove hair at the root. This method involves applying a sticky substance, typically a warm wax, to the skin in the direction of hair growth and then quickly pulling it away, which removes the hair along with its root from the follicle. This process results in smoother skin for an extended period compared to methods that only cut the hair at the surface, such as shaving or trimming.

While shaving involves cutting the hair at the surface level and trimming can effectively shorten hair without removing it from the root, both methods do not provide the long-lasting results that waxing offers. Cleaning, on the other hand, refers to removing dirt or product from the skin and does not contribute to hair removal. Therefore, waxing stands out as the only technique listed that effectively targets hair removal from the root.
