There are three types of electrolysis hair removal: galvanic, thermolysis, and blend, which combines the prior two. Both galvanic and thermolysis treatments use electrical currents, but each uses a different conductor to create a different reaction within the follicle.Â
Galvanic electrolysis uses chemicals as a conductor. In this traditional method, the electric charge reacts with the natural saline in your follicle to produce sodium hydroxide. When the sodium hydroxide heats up, it destroys the follicle and the cells around it. It’s considered highly effective.Â
Thermolysis uses water and delivers radiofrequency rather than electric current. The needle transmits the waves at such a high frequency that it causes the follicle to vibrate, which triggers the surrounding water molecules. The motion produces heat energy, which then destroys the follicle. “Thermolysis, which uses a microwave type of technology to generate heat, is less effective for treating curly or distorted hairs but has the advantage of being far, far faster,” says Dr. Novick. While this method is quicker, it’s typically not as effective as galvanic. It’s also best suited to finer strands.
“Both are permanent hair removal methods and very operator-dependent, which means that the training, experience, and expertise of the person who performs the procedure are extremely important in determining success,” says Dr. Novick. Your particular provider may favor one method or have the equipment for only one of the two. Discuss which is best for you during your consultation.
