Electrolysis: Method of permanent hair removal using electric current

ByDr. Celestine (Certified Trichologist)

What is Electrolysis?

Electrolysis is a permanent hair removal method that uses electrical energy to destroy the hair growth cells within the follicle. A very fine probe enters the natural opening of the hair follicle near the surface of your skin. A small amount of current is then applied to the base of the follicle, which stops it from growing new hair. Most people don’t realize that the same electrical current used in electrolysis can also stimulate blood flow to the treated area, which can sometimes aid in the healing process after the follicle is disabled.

How Electrolysis Targets Your Hair Follicle

Think of your hair follicle like a tiny, self-contained factory for growing hair. Electrolysis sends a precise electrical signal directly to the factory’s power source. This current creates a chemical reaction that permanently shuts down the production line.

I see the best results when the follicle is in its active growth phase, known as the anagen phase. This is when the target cells are most vulnerable to the electrical current. The process requires immense skill, as the probe must be placed with perfect accuracy to be effective without damaging surrounding skin tissue.

Why Electrolysis Works on Every Hair Type

Unlike laser hair removal, which targets pigment, electrolysis works on any hair color and skin tone. It doesn’t matter if your hair is light, dark, blonde, or gray; the electrical current focuses on the follicle’s structure itself.

In my clinic, I’ve successfully treated clients with fine, fine hair and those with coarse, stubborn strands. The same principle applies regardless. The electrical current is simply adjusted for the size and depth of the individual follicle to ensure complete destruction of the growth cells.

The Electrolysis Process and What to Expect

A typical session involves inserting a ultra-fine, sterile probe into each hair follicle. You might feel a momentary heat sensation or a tiny prick, often described as a quick sting. Modern devices have advanced cooling systems to make this much more comfortable than in the past.

After the current is applied, the hair is gently removed. The skin may be slightly red and feel similar to a mild sunburn for a few hours post-treatment. I always advise my clients to avoid sun exposure and apply a soothing gel like pure aloe vera to calm the area immediately after their appointment.

Will Electrolysis Work For You?

Yes

  • If you have light, blonde, red, or white hair that laser cannot treat.
  • When you are seeking a method for permanent hair removal, not just reduction.
  • If you have the patience for a process that requires multiple sessions over time.

No

  • If you have an active skin infection, rash, or herpes outbreak in the treatment area.
  • When you use certain acne medications like isotretinoin (Accutane), which can make skin overly sensitive.
  • If you have a known history of keloid scarring or certain heart conditions with a pacemaker.

From My Experience

The most common misconception I combat is that electrolysis is excruciatingly painful. While sensitivity varies, technological advancements have made it far more manageable than its reputation suggests. Topical numbing creams can also be used for more sensitive areas.

I tell all my clients that consistency is the true key to success. Hair grows in cycles, so multiple sessions are necessary to catch each hair in its active growth phase. Skipping appointments prolongs the entire process. The reward for that commitment, however, is truly permanent freedom from unwanted hair, which I’ve seen boost confidence immensely.
