The sugaring technique can be traced back about 6,000 years to ancient Egypt. Modern hair waxing share the same technique, but use harmful chemical substances that quite often irritate the skin.
This hair removal method is even mentioned in the ancient Egyptian writings, called Hieroglyphics.
It is a godsend for those prone to allergies, because it contains no chemicals, resins or other harsh ingredients like commercial waxes do.
The product can be used as paste at room temperature.
But if you want to use it like cold waxing with strips, it is heated to a runny consistency. It can easily be washed off with water.
It is easy to prepare at home, or you can buy it at certain stores. I can't help with this outside of South Africa.
