Both electrolysis and laser removal have the potential to be permanent solutions after enough treatments. They are far more expensive than the other methods of hair removal, but they can save you a lot of time in the long run if you're constantly waxing or bleaching your mustache. During laser-hair removal, a laser is used to zap many hair follicles at once and kill hair at the root. Because the lasers are best at targeting dark hairs that stand out against light skin, it's not ideal for dark-skinned or light-haired people. Skin and hair color are less important for electrolysis, when a tiny needle is inserted into the hair follicle and creates a current that kills the root of the hair. Some places have better machines, more qualified specialists (always make sure they're licensed), and happier customer reviews than others. Look online for reviews, but never choose a location based on the testimonials on their company website. Call your top two or three choices for clinics and ask them questions about their services, equipment, and training. Some things to ask include how long they've been in business, how old their equipment is, whether their equipment is FDA approved, and whether their practitioners are licensed. Also ask about the total price, whether they'll let you do a patch test, what the possible side effects will be.
Choose electrolysis or laser removal for a permanent solution. Choose laser hair removal if you have dark hair and light skin. Research locations and practitioners carefully. Call a few clinics to interview practitioners.
