Electrolysis is permanent hair removal technique that works well on all skin types. While laser works primarily on dark hair, electrolysis can be used on any hair and skin color. High frequency and direct current are combined to produce both heat and a chemical reaction in the individual hair follicles. This reaction weakens and destroys the cells that provide nourishment to the growing hair causing it to become finer and finer until it is completely destroyed. Several rounds of treatment are required to permanently remove hair.
