Electrolysis vs. Laser Hair Removal: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Updated on October 30, 2023
Electrolysis involves using electric current to destroy hair follicles, while laser hair removal uses light energy to target pigment in the hairs

Key Differences

Electrolysis is a method of hair removal that utilizes an electric current to destroy the root of individual hairs. This process is considered permanent because it targets the hair follicle directly. On the other hand, laser hair removal employs concentrated light beams, targeting the melanin in hair to hinder the growth of hair follicles. Both methods are sought after for long-term hair reduction or removal.
Electrolysis has been around longer than laser hair removal. While both processes are effective, electrolysis can be more time-consuming as it treats individual hairs. Laser hair removal, in contrast, can treat many hairs at once, making it faster for larger areas like the legs or back.
One key difference between electrolysis and laser hair removal is their suitability for different skin and hair types. Electrolysis works on all skin tones and hair colors because it doesn't rely on melanin. Laser hair removal, however, is most effective on individuals with light skin and dark hair due to the technology's reliance on targeting melanin.
The level of discomfort varies between electrolysis and laser hair removal. Some find electrolysis to be more painful because it involves inserting a tiny needle into each hair follicle. Laser hair removal can cause a sensation akin to a rubber band snapping against the skin. Both methods might require multiple sessions for optimal results.
