About Laser Hair Removal

This noninvasive laser treatment uses gentle beams of light to get rid of hair. The hair’s melanin (the part that gives hair its color) absorbs the light, which turns into heat. The heat damages the follicle (but not the surrounding skin or tissue) and prevents it from producing more hair.

When sorting through different lasers it’s important to recognize that these 3 laser wavelengths are the only types of lasers that are used for hair removal. As there are lots of different types of laser available, the specific technology used for professional laser hair removal equipment is a long pulsed laser. This means the time the laser “rests” on the skin is longer, but in relation to 1 second it is still very fast. The laser rests on the skin in a fraction of a second but is still longer than a Q switch laser. A Q switch laser is used for tattoo removal and operates in a shorter resting time than a long pulsed laser used for hair removal. 

Benefits of Laser Hair Removal

"Laser hair removal can treat hair anywhere on the face or body. Women often treat the bikini area, chin, upper lip, and legs. Men can safely eliminate unwanted hair from places such as their chests and backs."

"Precision. Lasers can selectively target dark, coarse hairs while leaving the surrounding skin undamaged."

"Speed. Each pulse of the laser takes a fraction of a second and can treat many hairs at the same time. The laser can treat an area approximately the size of a quarter every second. Small areas such as the upper lip can be treated in less than a minute, and large areas, such as the back or legs, may take up to an hour."

"Predictability. Most patients have permanent hair loss after an average of three to seven sessions."

Am I A Candidate?

Laser hair removal works when the light beams are absorbed by the melanin in the hair shaft and follicle. People with dark hair are considered the best candidates. Blonde, gray, and strawberry-blonde hair may not absorb the laser light. And contrast between the hair and your skin is also important, so people with dark skin may not have enough contrast for the beams to be absorbed by the hair follicle.

Each person responds differently to laser hair removal. Some may require more treatments than others. And sometimes laser hair removal can’t eliminate hair completely. If some hair does grow back, it’s usually thinner and finer than before the treatment.

What Can I Expect Before and After Treatment?

Before Your Treatment

You can prepare for laser hair removal by not waxing or plucking hairs in the treatment area for 4 to 6 weeks before your treatment; hair follicles must be present to be treated. You can still shave and, in fact, you’ll be asked to shave your treatment area 24 to 48 hours before your scheduled appointment.

Because laser hair removal depends on the color of your skin and hair, you should not sun tan for a minimum of 6 weeks before your treatment.

After Your Treatment

There may be some redness or bumps immediately after the treatment, but nothing expected to keep you from your daily activities. Some people briefly apply an icepack to their treatment area. You don’t need time to recover after your session, so you can participate in almost all your regular activities immediately after your appointment. You should, however, avoid exposure to the sun for the following 4 to 6 weeks.

How you prepare

If you're interested in laser hair removal, choose a doctor who's board certified in a specialty such as dermatology or cosmetic surgery and has experience with laser hair removal on your skin type. If a physician assistant or licensed nurse will do the procedure, make sure a doctor supervises and is available on-site during the treatments. Be cautious about spas, salons or other facilities that allow nonmedical personnel to do laser hair removal.

Before laser hair removal, schedule a consultation with the doctor to determine if this is an appropriate treatment option for you. Your doctor will likely do the following:

Review your medical history, including medication use, history of skin disorders or scarring, and past hair removal procedures

Discuss risks, benefits and expectations, including what laser hair removal can and can't do for you

Take photos to be used for before-and-after assessments and long-term reviews

At the consultation, discuss a treatment plan and related costs. Laser hair removal is usually an out-of-pocket expense.

The doctor will also offer specific instructions to prepare for laser hair removal. These might include:

Staying out of the sun. Follow your doctor's advice for avoiding sun exposure before and after treatment. Whenever you go out, apply a broad-spectrum, SPF30 sunscreen.

Lightening your skin. Avoid any sunless skin creams that darken your skin. Your doctor might also prescribe a skin bleaching cream if you have a recent tan or darker skin.

Avoiding other hair removal methods. Plucking, waxing and electrolysis can disturb the hair follicle and should be avoided at least four weeks before treatment.

Avoiding blood-thinning medications. Ask your doctor about what medications, such as aspirin or anti-inflammatory drugs, to avoid before the procedure.

Shaving treatment area. Trimming and shaving is recommended the day before laser treatment. It removes hair above the skin that can result in surface skin damage from burnt hairs, but it leaves the hair shaft intact below the surface.

Will I need multiple treatments?

You’ll likely need anywhere from six to eight laser hair removal treatments. Sessions are usually about six to eight weeks apart. This timing helps capture more hairs in different growth phases.

How long do the effects of laser hair removal last?

Most people see about a 10% to 25% reduction in hair growth after the first treatment. After all your treatments, you may not have new hair growth for several months or years.

Is laser hair removal permanent?

Laser hair removal isn’t permanent. It’s unlikely that treatments will target all the hairs in their growth phase. Some hair will grow back, but it’s usually lighter and thinner than before.
