There are three main types of hair removal. The first is shaving. This is the most inexpensive way to remove unwanted hair, but it only skims the surface of your skin, allowing hair to grow back within a matter of days. Having an electric shaver allows people to conveniently shave their hair without water and shaving cream. The next type of hair removal is chemical depilation. This is a formula applied to the skin that takes about 10 minutes to work, has an unpleasant odor, but gives a smoother "cut" than shaving and takes longer for hair to grow back. Lastly, epilation is the most expensive route since it removes the entire hair including what is below the skin for a more permanent effect.
