Permanent hair removal is a dream come true for people who have spent years shaving, waxing, plucking, and trimming unwanted hair every few weeks. Laser hair removal and electrolysis are innovative cosmetic treatments that provide just that: long-term and, in many cases, permanent hair reduction.
This article compares laser hair removal against electrolysis, explaining both procedures and their effects.
Electrolysis Overview
Electrolysis involves the use of an epilator that penetrates the skin with a fine needle, aiming for the hair follicle. The pen-like device is connected to a machine that sends an electric current through the needle to the hair root, destroying the follicle and stumping future hair growth.
Electrolysis is the only FDA-approved treatment for permanent hair removal.
Laser Hair Removal Overview
Laser hair removal uses intense light pulses to heat and destroy hair follicles. The light targets melanin in the hair, bypassing the skin. Patients need to have a clear contrast between hair and skin color so the laser can recognize the targeted pigment.
Laser hair removal is FDA-approved for permanent hair reduction.

The Procedures
Electrolysis
Your chosen medical provider cleans your skin, inserts the probing needle into a hair follicle, and removes the loosened hair. The provider repeats the process for each hair follicle. The whole procedure takes between 15 minutes and an hour, depending on the size of the treatment area.
You may feel an unpleasant hot or stinging sensation every time the needle is inserted because a low-level electric current runs through the needle to destroy the hair follicle.
After the treatment, you can resume your daily activities.
Laser Hair Removal
Your chosen medical provider cleans your skin and applies a numbing cream if necessary. You will wear protective goggles during the session. The laser blast treats several hair follicles at once, which makes the process faster than electrolysis. Depending on the treatment area size, the procedure can last between a few minutes and an hour.
Patients typically don’t feel pain during the treatment. You may feel a mild prickling sensation.
You can resume your regular activities after the treatment.
The Results
Electrolysis
Since hair grows in cycles, patients need to undergo multiple treatments to target all hairs in the proper growth stage. The sessions are spaced one or two weeks apart, and typically run for up to 18 months.
You will notice less hair in the treatment area after a few sessions, which will make each following session shorter. The hairs are permanently destroyed after the final session, and no maintenance treatments are required.
Laser Hair Removal
The first laser hair removal session reduces hair by up to 25%, and the treated hairs start falling out a few weeks after the treatment. You will need six to eight treatments to reduce hair growth and annual maintenance treatments to target the hairs that return. The hair that grows back is finer and lighter.
The FDA doesn’t recognize laser as a permanent hair removal method but as an effective hair reduction treatment. However, the American Academy of Dermatology Association claims that “laser hair removal is permanent on most body areas, except for the face in women, due to hormones.”

Electrolysis has been in use in medicine for over 100 years. It is FDA-approved and considered safe for most healthy adults, when performed by trained and licensed cosmetic professionals. Common side effects include redness and swelling that typically subside within several hours.

Which One Is Better for Hair Removal: Laser or Electrolysis?
Laser hair removal and electrolysis both provide impressive results. Each has certain advantages over the other, which can help you decide.
Electrolysis is the only permanent hair removal treatment that requires no maintenance treatments. It can address any hair color and skin type, which makes it a suitable option for people with blonde, white, gray, or red hair.
It also carries fewer risks than laser hair removal.
Laser is quicker than electrolysis because it targets several hair follicles at once, and it is less painful. It eventually achieves permanent results in most cases, or the hair becomes so fine and sparse that the treatments become unnecessary. The laser also improves skin tone and texture because it stimulates collagen production.
However, it requires a clear contrast between hair and skin color and is ineffective in people with fair hair.
Conclusion
Laser hair removal and electrolysis are replacing traditional hair removal methods such as shaving and waxing because they provide long-lasting results. The laser also helps smooth and rejuvenate the skin, and it is currently the most popular hair reduction treatment.
Consult a trusted skin professional in your area about your options and the best treatment plan to permanently remove unwanted hair once and for all.
