Sierra Foothills Electrolysis, Loomis

As its name suggests, Sierra Foothills Electrolysis specializes in using electricity to permanently clear bodies of unwanted hair. Electrolysis—the only FDA-approved treatment for permanent hair removal—uses a disposable stainless-steel probe to administer electrical currents small enough to zap off hair without damaging skin or creating beauty marks shaped like lightning bolts. Depending on the size and hair density of the treatment area, sessions can last anywhere from 15 minutes to two hours.
