Electrolysis is most effective during the early Anagen phase. When a new hair begins to surface the skin, it is at its weakest point. This is because the dermal papilla is in the process of nourishing the hair to grow stronger. By treating the dermal papilla with electrolysis at its weakest point, the treatment is the most effective at achieving permanent hair removal. Because hair grows at different stages on different parts of the body it is important to commit to regular treatments in order to target hairs during the active stage (Anagen Stage).
