Electrolysis

Electrolysis removes unwanted hair

What it is: Electrolysis is the process of permanently removing unwanted hair by means of electricity. It’s used by both men and women and takes several treatments (generally 1.5 to 2 years) to become permanently effective.

How it works: There are actually three distinct types of electrolysis: galvanic, thermolysis and a blend of the previous two. In all instances, a thin needle-shaped probe is inserted into a single hair follicle and introduces an electric current (the FDA says it’s a shortwave radio frequency) in order to destroy it. The way the current destroys the follicle varies by type:

• Galvanic: The current is direct and chemically reacts with the salt and water within the hair follicle to create lye, a highly concentrated sodium hydroxide, which then burns the hair and destroys the follicle.

• Thermolysis: The current is alternating, or high frequency, and produces heat to burn the hair and destroy the follicle.

• Blend: Both methods are used so that heating and chemical actions occur simultaneously to burn the hair and destroy the follicle.

Is it safe? The FDA states that electrolysis “is considered a permanent hair removal method, since it destroys the hair follicle.” In comparison, the laser hair removal method has not been proved to be as generally effective; each laser manufacturer must be individually approved by the FDA, and the FDA states that several laser hair removal manufacturers received permission to claim “permanent reduction” but not “permanent removal” for their lasers.

Risks associated with electrolysis include infection from an unsterile needle and skin discoloration or scarring from improper technique. To avoid these risks, take care to select a skilled practitioner, and feel free to ask for references.

Does it hurt? While the terms “needle,” “destroy” and “two years” may sound pretty intimidating, the pain factor depends on personal tolerance — it’s been likened to a stinging or pricking sensation (the tedious task of attacking each hair follicle individually might test patience more than pain tolerance). If done correctly, the needle will not actually puncture the skin. Still, there is a noticeable sensation produced by the electrical current and it can be unpleasant to some people.
