The electrolysis machine is used for permanent hair removal by delivering a small electrical current to individual hair follicles, destroying the hair root. This method is effective for all hair types and is particularly beneficial for clients with lighter hair colors that may not respond to other hair removal methods like laser. Electrolysis is a precise and permanent solution for hair removal, offering clients long-term results. While the process can be time-intensive, it is highly effective, making it a valuable option for clients seeking a permanent hair removal solution.
