If you’re considering laser hair removal, you’re in good company. This increasingly popular treatment offers a semi-permanent solution to unwanted hair on various areas of the body, from legs and underarms to more sensitive areas like the face laser hair removal. Here’s everything you need to know to get started with laser hair removal.
What is Laser Hair Removal?
Laser hair removal is a cosmetic procedure that uses concentrated light energy to target hair follicles. The laser emits a beam of light absorbed by the pigment (melanin) in the hair. This light energy converts to heat, damaging the hair follicle, which inhibits or delays future hair growth.
Unlike shaving, waxing, or tweezing, laser hair removal provides a longer-lasting result and can significantly reduce hair growth over time.
How Does Laser Hair Removal Work?
- Targeting the Hair Follicle
The laser emits light that specifically targets the pigment in the hair. When this light is absorbed by the melanin, it heats up, damaging the hair follicle to the point where it can no longer grow hair as quickly—or at all. - Heat Damage to the Follicle
The heat from the laser creates a controlled injury to the follicle, slowing down hair regrowth. After several treatments, hair in the treated area becomes finer and grows back less frequently. - Multiple Sessions
Hair grows in cycles, and laser hair removal can only target hair in the active growth (anagen) phase. This is why multiple sessions are typically necessary, spaced several weeks apart, to capture each hair during its active growth stage.
Who Can Benefit from Laser Hair Removal?
Laser hair removal is effective for many skin types and hair colors, though it works best on people with light skin and dark hair. Advances in laser technology now allow for treatments on a broader range of skin tones and hair colors, but lighter hair colors (like white, gray, or very light blonde) may not respond as well.
What Areas of the Body Can Be Treated?
Laser hair removal can be applied to nearly any area of the body with unwanted hair, including:
- Face (upper lip, chin, cheeks)
- Legs
- Underarms
- Bikini area
- Back and chest
What to Expect During and After Treatment
- Preparation
It’s usually recommended to shave the area to be treated a day or two before the session. Avoid waxing or plucking, as these remove the follicle that the laser needs to target. - The Procedure
During the treatment, a laser technician will use a handheld laser device on your skin. You may feel a snapping sensation as the laser works, but most people find the process only mildly uncomfortable. Sessions can last anywhere from a few minutes to an hour, depending on the area being treated. - Aftercare
You may experience redness or slight irritation afterward, similar to a mild sunburn. Avoid sun exposure and wear sunscreen on treated areas to prevent further irritation. - Results
After the first few sessions, many people notice a significant reduction in hair growth. With each session, the hair that does grow back becomes finer and less dense. Typically, 6–8 treatments are needed to achieve optimal results.
Frequently Asked Questions
Is laser hair removal safe?
Yes, when performed by a trained technician. The lasers used in professional settings are FDA-approved and undergo rigorous testing for safety.
Does it hurt?
Laser hair removal is usually only mildly uncomfortable, with many people describing the sensation as a light rubber band snap.
How long does it last?
Results vary by individual, but many people experience long-lasting reduction in hair growth. Some may require maintenance sessions annually or bi-annually to maintain results.
Can I do laser hair removal at home?
There are at-home laser devices available, but they generally aren’t as powerful as professional-grade lasers, so the results may not be as effective or long-lasting.
