Sugar is a natural way to remove hair, I have been using sugar in the salon for over 25 years and would not use anything else.
Wax is made of resins, perfume and colourants so can cause reaction to the skin and ingrowing hair but can also leaves a residue on the skin but sugar is made of sugar and lemon juice has far less reaction, gentle and kinder to the skin and is water soluble and pulls hairs from the root .
Pop into the salon and try it out for yourself.
I have tried this already and it really works! Very simple technique but much effective!
