Efficacy:

Laser hair removal is a noninvasive way to reduce or remove unwanted body hair. With more than one million procedures performed in 2016, laser hair removal is one of the most popular minimally invasive cosmetic treatments in the United States. It can be a good option for those with excess body hair who are looking for a way to effectively reduce or remove hair from both large and small areas of the body.

Before the procedure, a medical specialist (a physician, physician assistant, or registered nurse) cleans the treatment area. If the area is particularly sensitive, numbing gel can be applied. During the procedure, everyone in the room needs to wear special protective eyewear to prevent eye damage from the laser.

Once the numbing gel kicks in, the medical specialist focuses a beam of high-energy light at the desired area. The bigger the area you would like treated, the longer the procedure takes. Small areas can take as little as a couple of minutes while larger areas such as the chest can take an hour or more.

Some patients report a sensation similar to a rubber band snapping or a sunburn-like sting. As the hair vaporizes from the energy of the laser, there can be a sulfurous smell from the smoke puffs.

Your doctor should provide thorough preparation instructions before your appointment. Following these instructions improves the effectiveness of the procedure and reduces the risk of side effects. Here are some common recommendations:

  • Stay out of the sun for a few days before the procedure. Laser hair removal shouldn’t be performed on tanned skin.
  • Avoid irritating the skin.
  • Stay away from waxing and plucking.
  • Try not to take anti-inflammatory drugs that may increase bleeding, such as aspirin.
  • If you have an active infection, such as a cold sore or bacterial skin infection, the procedure should not be performed.

Additionally, if you have dark skin you might be recommended to apply a skin-bleaching compound to the treatment area.

Target areas include:

  • back
  • shoulders
  • arms
  • chest
  • bikini area
  • legs
  • neck
  • upper lip
  • chin

Laser hair removal works by using concentrated light to affect hair follicles, which are small cavities in the skin from which hair grows. The hair follicle absorbs the laser, which is attracted to the hair’s melanin pigment, and the hair vaporizes instantly.

The pigment in the hair attracts the laser, so darker hair absorbs the laser more effectively, which is why people with dark hair and light skin are ideal candidates for laser hair removal.

Patients with dark skin typically need to be treated with a special type of laser that detects the hair against their skin.

Those with light hair make less ideal candidates, and they are also less likely to experience drastic results as the laser doesn’t focus well on nonpigmented hair. Laser hair removal is not effective on blonde, gray, or white hairs.

Serious complications related to laser hair removal are rare. The most common side effects include:

  • swelling
  • redness
  • discomfort and skin irritation

They typically subside within a few days after the treatment. If symptoms persist, you should contact your medical specialist.

Less common side effects include:

  • scars
  • burns
  • blisters
  • infections
  • permanent changes in skin color

Carefully choosing a skilled medical professional can greatly reduce these risks. The American Academy of Dermatology recommends only having laser hair removal performed by a board-certified dermatologist to minimize any risk of complications.

The recovery time after the procedure is minimal and most patients can return to life as normal directly after. Just as wearing sunscreen before the procedure is important, so is continuing to wear it after the procedure. This will help prevent further irritation.

You can expect to see a reduction in the number of hairs in the treated area immediately after the procedure. Two to eight weeks after laser hair removal, you may begin to notice an increase in hair growth in the treated area. The reason for this is that not all hair follicles respond equally to the laser. Most patients see a 10 to 25 percent reduction in hair after the first treatment. It typically takes between three and eight sessions for permanent hair loss. The evaluation with your specialist before the procedure will give you a better idea of how many treatment sessions you may need. Also, you will likely need a touch-up session yearly to maintain effect.

Cost varies based on multiple factors including:

  • the specialist’s experience
  • geographic location
  • size of the treatment area
  • number of sessions

As of 2016, laser hair removal cost $306 per session on average, according to the American Society of Plastic Surgeons (ASPS). Most offices offer payment plans.

As an elective procedure, laser hair removal is not covered by medical insurance.

Do some people not respond to laser hair removal? ›

While laser hair removal has proven to be a highly effective and popular method for reducing unwanted hair, it may not work equally well for everyone. Factors such as hair color, skin type, hormonal imbalances, and individual characteristics can influence the outcome of the treatment.

What happens if I stop laser hair removal after 4 sessions? ›

Sometimes, the patient sees hairs are thicker and darker after the treatment when they have original light and fair hair.

Does laser remove 100% hair? ›

In short, no. Laser hair removal works by heating the hair follicles to stop new hairs from growing. This puts the hair follicles in a state of dormancy for a long period of time — much longer than with shaving and waxing. When the hairs do grow back, they'll be lighter, finer, and fewer in number.

How many laser sessions does it take to permanently remove hair? ›

As a general rule of thumb, the majority of patients need four to six sessions. Individuals rarely need more than eight. Most patients will see results after three to six visits. Additionally, treatments are spaced out about every six weeks since individual hairs grow in cycles.

After 6 sessions, laser hair removal will be optimally effective on large pigmented hairs on which a reduction of between 69% and 90% of the hair will be obtained.

Why am I still hairy after laser hair removal? ›

Hair Growth Cycles – Hair growth occurs in cycles, and not all of the hair in a given area is in the same growth phase at the same time. This means that some hairs may not be affected by the laser during the initial treatment, and may continue to grow as normal.

Why am I more hairy after laser? ›

No one actually knows why this happens with laser patients, but after treatment, the laser can do the opposite of what you're expecting and actually stimulate hair growth. And, if that wasn't enough, the hair can actually come back thicker and darker!

Why do I still have so much hair after laser? ›

Patients may notice more hair 1 – 3 weeks after laser hair removal sessions as follicles in the growing cycle begin to shed. During this process, exfoliating the skin, once swelling and redness have dissipated, can help hairs shed faster, leaving skin feeling smoother.

Do people ever regret laser hair removal? ›

Regret usually stems from choosing the wrong provider. While laser hair removal itself is rarely regrettable, what can lead to regret is choosing the wrong provider. A cheap, inexperienced clinic may use outdated equipment or incorrect techniques, leading to less effective treatment or even unwanted side-effects.

Does laser work on hormonal hair? ›

But many wonder if it's effective on hormonal hair. The answer is yes, laser hair removal can work on hormonal hair. However, the effectiveness of laser hair removal on hormonal hair can vary depending on the individual and the type of hormonal hair growth.

Is electrolysis or laser better? ›

You might not see full results for nearly 18 months.

Should I laser my pubic hair? ›

' Yes, it is safe to laser the pubic area for most patients. It should be noted that this is one of the more sensitive areas when it comes to laser hair removal, but it is quick and effective. Many patients also believe it is overall less painful than waxing.

How long after laser hair removal do you see results? ›

As a general rule of thumb, you can expect to see the results of each session one to three weeks after your session is complete. After that, you need to wait until the hair follicles in the area enter the active growth phase.

Who should not get laser hair removal? ›

People with keloid scars or healing problems like hypertrophic scars should not have laser hair removal. Likewise people with vitiligo, a condition which causes de-pigmentation of sections of the skin. People who have severe histamine reactions like urticaria are also unsuitable.
