Electrolysis hair removal is the only method approved by the FDA for permanent hair removal.  It does require multiple sessions to achieve best possible results, but permanent hair removal isn't 100% guaranteed for everyone.

How does it work ?

 An electric current is applied with a very fine needle-shaped electrode, or metal probe into each hair follicle destroy the root. There are three types of electrolysis: galvanic, thermolysis and blend.

Hair grows in different stages: growing, resting and shedding. Because all of the hair isn’t on the same stage at any given time, multiple sessions are needed to get the hair in the growth phase for electrolysis hair removal to be most effective- just like laser hair removal.
