Waxing is one way of body hair removal which has its origin in Brazil. In Germany it is known as `Brazilian Waxing`.

The wax is applied in direction of hair growth and is removed in the opposite direction.

There are various waxes.
The hot wax is mainly used for bikini zone, arm pits and sometimes for the face. For this method there is no need to use a fleece because the wax hardens on the Skin after a few seconds and can be pulled off afterwards.
The warm wax is applied with a Roll-on and removed with a fleece. It is used at the larger areas of the body e.g. legs, arms and back. It can also be used for the face. In that case I would use a small spatula to apply the wax in order to work more detailed and to provide the best results. Waxing can be done on every body part with every wax.

Which technique is the best for me?

In order to choose the right type of hair removal you have to decide for yourself what suits you best. If you tend to have a lot of ingrown hair and are more sensitive to pain I would recommend sugaring. I can tell you from my own experience that the `pain´ is the same in both methods - depending on your daily mood. One day the waxing/sugaring doesn’t hurt at all, the other day it does. While sugaring the dead skin cells are removed. Since the sugaring paste is just warmed up but not hot, for some clients it feels more comfortable than waxing. The skin doesn't get as much irritated. On larger body parts e.g. legs and back sugaring is more time consuming, that explains the price difference.
