The number of treatments necessary varies with each client. Treatment sessions can range from 15 minutes to more than an hour depending on the area being treated. Factors such as hair growth cycles, the quantity and structure of hair presented, previous use of temporary hair removal methods, heredity, hormone function, certain medications, and stress influence the treatment program for each individual. Electrolysis is effective on all skin and hair types. No other hair removal solution can claim such universal acceptability and success. It is important to follow the recommended treatment plan to achieve optimum results.
