Penelope's uses PhD Safewax which is a hygienic, quick, easy and less painful hair removal service, with the assurance that there is no danger of infection. The unique PhD applicator is attached to a tube of high quality wax and is applied directly and evenly onto the treatment area. The applicator is thrown away after each treatment eliminating the risk of cross contamination. PhD is the original, tried and tested tube applicator waxing system. Unlike other waxing methods PhD is a totally safe system that eliminates the risk of cross infection from one client to another.
