Electrolysis for Removing Hair (2024)

Treatment Overview

Electrolysis is a common method of removing unwanted hair. A small needle or thin metal probe is inserted into the opening of the skin where hair grows (small sacs beneath the skin called hair follicles). Next, a low-level electrical current passes through the needle or probe into your skin and destroys the hair follicle. Hair is unable to grow back in an area where the follicle has been destroyed.

The process of electrolysis can be slow and can require several treatment sessions to destroy the hair follicles. Treatment can be uncomfortable. The destruction of each individual hair follicle may take a few seconds.

What To Expect

After electrolysis, your treated skin may temporarily be red, swollen, and tender. You may need additional treatments to permanently remove all unwanted hair. You should notice a loss of unwanted hair in the treated area within several weeks to months after the first treatment.

Why It Is Done

Electrolysis is done to permanently remove unwanted hair. It is commonly used to remove hair on the face (eyebrows, upper and lower lips, cheeks, chin, hairline, bridge of the nose between eyebrows, and sideburns) and also on the neck, shoulders, arms and underarms, breasts, abdomen, bikini line, legs, back, and chest.

Electrolysis should not be done on the inside of your ears or nose. It also should never be done to remove hair from a mole or a birthmark. If you have a pacemaker, you should not have electrolysis on any part of your body.

How Well It Works

When electrolysis is done correctly, it permanently removes unwanted hair. Successful hair removal depends on the skill of the person doing the electrolysis.

Risks

Electrolysis poses few risks in a healthy person. During treatment, you may feel some pain from the electrical current flow. After treatment, your skin may be red, swollen (inflamed), and tender. These are temporary side effects. Electrolysis can cause scarring, keloid scars, and changes in skin colour of the treated skin in some people.
