The fact is, we are all different, and each of us has unique physiological characteristics: hair color, structure, growth direction, and density.
These factors directly affect the duration of the procedure since each hair is removed one by one. Electrolysis of the same zone for two different clients will take different amounts of time. For one, it may take 30 minutes, while for another, 60-80 minutes. 😅
If the specialist were to charge by the zone, it wouldn’t be fair. After all, those with fewer hairs in the zone would end up overpaying.
