How Long Does Laser Hair Removal Last

How long does laser hair removal last?

Laser hair removal is a chronic form of hair removal that damages or destroys the hair follicles.

However, the hair can become new again, especially if the gland is damaged rather than destroyed during laser hair removal.

Because of this, many doctors today refer to laser hair removal as long-term hair removal instead of permanent hair removal.

Learn how laser hair removal works, how long it takes, and what the cost of laser hair removal methods is.

How does laser hair removal work?

Laser hair removal uses light to identify the pigment in individual hair. The light travels down the hair follicles and into the hair follicles

The heat from the laser light destroys the hair follicles and hair can no longer grow from them.

Hair follows a unique development cycle that includes rest, hair loss and growth time. Recently removed hair that is at rest is not visible to a technician or laser, so someone has to wait to be shaved again before removing it.

For most people, laser hair removal requires a variety of treatments over 2 to 3 months.

Is Laser Hair Removal Permanent?

Permanent hair removal from damaged hair follicles. However, removing people can lead people to expect some hair to return to the destination.

Over time, it is possible to re-treat the area to reduce the number of hairs that remain. In some cases it may be possible to remove all of the hair.

Whether or not hair will grow back depends on a number of factors, including the type of hair and the ability of the person who is cutting the hair.

Most people find that hair removal is easier and less noticeable than it was before. This is because the laser can damage the hair follicles even if it isn’t damaged.

When a hair follicle is damaged but not destroyed, the hair eventually regenerates. It can be difficult to destroy every single hair follicle, so most people see hair regrowth.

If the hair is removed again it is possible to treat it again, so each hair that wants to remove all hair may need different treatments.

In some cases, the hair can be too light, too short, or treatment-resistant. In this case, a person may prefer other methods of hair removal, such as lifting the stray hair.

How long does laser hair removal take?

Laser hair removal is permanent when the hair follicle is damaged. If the hair follicle is simply damaged, the hair will eventually begin to regenerate.

How long it takes for hair to grow back depends on a person’s unique hair growth cycle. Some people have hair that grows faster than others. Hair that grows at rest grows more slowly than at other stages.

Most people can expect some hair to grow back in a few months. Once that’s done, they can choose additional treatment options for the removal.

Is there a difference in skin or hair color?

It is best to remove light-colored people with black hair. This is because the pigment contrast makes it easier for the laser to aim at the hair, move between the follicles, and destroy the follicles.

People with darker skin or lighter hair may need more treatment than others, and more hair can grow backwards.

In order to remove hair permanently, the technician needs to know how to aim the hair and choose the right type of laser. A study published in 2013 found that lasers that produce longer wavelengths work best on darker skin.

Side effects and risks

Some people feel burning, stabbing, or uncomfortable during treatment. For this reason, many technicians apply a moisturizer to the area they are treating. However, some people may have allergic reactions or skin irritation due to random cream reactions.

Secondary side effects are common and can include:

Changes in skin color, especially in people with darker skin, are usually temporary
Reddening of the skin
Rash or skin crust

Occasionally, there may be irritation related to hair removal. Damaged skin can also become infected. Although rare, skin infections can spread and be fatal.

By providing a detailed treatment history and discussing the risks and benefits, the provider can determine the right treatment by reducing the risk of serious side effects.

After hair removal, a person should avoid exposure to the sun. The sun can irritate the skin, increasing the risk of blisters and blemishes.

People with severe pain, fever, crusting, blisters, or other symptoms of skin damage or infection should see a doctor.

The cost of laser hair removal

The average cost of a hair removal session is $ 293, according to 201 statistics from the American Society of Plastic Surgeons.

Most people will need multiple sessions so they should speak to their practitioner about how many sessions it will take to determine the total cost.

Laser hair removal is almost always a cosmetic procedure, so it is less likely to be covered by insurance.

The total cost of laser hair removal depends on a number of factors, including the person performing the treatment. Qualified nurses like dermatologists and plastic surgeons may charge more but have fewer injuries or side effects.

Other factors that affect spending include:

Number of treatments required
How much hair again
The number of targeted hairs
The size of the field required for treatment

Removing a small amount of hair from an area like the upper lip costs less than removing hair from the entire leg.


Laser hair removal can significantly reduce a person’s body hair volume. In most people, some hair will come back over time.

Even when the hair comes back, there is less hair overall, which creates a smoother look. Discuss treatment goals with a treatment or hair removal specialist to get a clear idea of ​​what to expect from laser hair removal.

Some skin complications and hair types produce better results than others. The only way to be sure of what to expect is to speak to a doctor, dermatologist, or other professional


Here’s How Long Your Laser Hair Removal Will Actually Last

Laser hair removal is an expensive but effective way to get rid of unwanted hair. People are fed up with shaving, cutting, or waxing.

But spending thousands of dollars on necessary treatments doesn’t always guarantee that body hair will come alive. Below, plastic surgeons and dermatologists explain how laser hair removal works, how much it costs, and how long it takes.

How does laser hair removal work?

Dr. Robin Gamerick, a dermatologist at Union Square Laser Dermatology in New York City, said, “The laser light comes with hair dye and sits on top of the hair follicles,” said Dr. Robin Gamerick. “When laser light is absorbed, it generates heat. If enough heat is generated under the hair follicles, the hair growth center in the follicle is destroyed. If the hair growth center is destroyed, you shouldn’t create new hair.

Gimerek explained that body hair goes through a cycle of rest and growth, which is why continuous follow-up treatment is prescribed every 4-6 weeks.

“If the hair is in the rest of the cycle, it may not be able to absorb enough laser light or generate enough heat to destroy the hair growth center,” he said. “This means you have to do lasers more than once – usually about 6 sessions – to remove enough hair from each area.”

Treatment can be expensive.

The cost, methods, and effectiveness of treatment depend on each person’s skin type, hair thickness, and area to be covered.

“Regardless of the area you are treating, it takes about 6 treatments to achieve about 80 percent clearance. It’s based on hair cycling, ”said Zimmerick.

“Small areas like the upper lip can cost anywhere from 150 150 to 250 250 per session, while larger areas like bikinis, Brazilian bikinis, and full legs and backs can cost $ 500, 700 and $ 1,200, respectively, to treat,” she said. “Remember that treating the upper lip takes only a few pulses and only a few minutes, while a full foot treatment can take up to an hour of laser treatment and more than 1,500 laser pulses.”

It doesn’t work for everyone.

The three doctors we consulted who agreed with the ideal candidate for laser hair removal were very fair people with dark, thick hair. People with red, blonde, strawberry blonde, white, or very fine hair have a much harder time seeing results.

“That’s because the hair doesn’t have enough pigment to absorb the laser light. If not enough laser light is absorbed, the heat generated will be too little to destroy the gland cells and the treatment will fail, “explained Zimmerk. For those who are not good candidates for the laser, he suggested electronic analysis.

“Therapeutic electrolyzers destroy hair growth with a short-wave radio frequency after a thin probe into the hair follicle,” he said. “Electronic analysis is considered a permanent hair removal method because it destroys hair follicles.” Several appointments are required for the duration.

People with fair skin may respond well to laser hair removal.

According to Dr. Human Khorsani, head of dermatological and cosmetic surgery at the Icon School of Medicine at Mount Sinai Hospital in New York City, makes it possible to treat people with oily skin by reducing energy consumption and using longer-wave light. However, he said that people with darker skin are more likely to have hyperpigmentation or darkening of the skin as a side effect of the treatment.

Gimerek agreed that people with fair skin could get great results with laser hair removal, but suggested finding a test site for the treatment first.

“There is a special laser called ND: Yag that is safe for skin types,” he said. “Patients with oily skin should proceed with caution, contact a doctor experienced in treating oily skin and, because of the increased risk of skin discoloration from the laser, complete the laser exam before treating a larger area.”

Laser hair removal is not always permanent.

Dr. Wright Jones, plastic surgeon and founder of Music Plastic Surgery in Atlanta, told Halfpost, “Hair growth is unlikely to be permanent hair follicle removal because hair growth is multi-stage and can be influenced by hormones or ions. “Multiple treatments can lead to long-term hair loss, but patients shouldn’t expect permanent hair removal.”

Khorsani said laser hair removal is typically 80 to 90 percent effective at hair removal.

He said, “Hair can always come back.

Finding the right supplier is the key to success.

The most important thing about laser hair removal is finding the right doctor with the right qualifications for you. Otherwise, you will be throwing money into multiple treatments that won’t work and could ultimately hurt you.

“It is universal that patients find an experienced provider who understands how each treatment can be tailored to a specific skin type and hair color,” Wright said.

Gimerek said, “Laser hair removal can be dangerous for inexperienced hands. “I strongly recommend that you seek treatment from a specialist dermatologist who is trained in the use of lasers and who has in-depth knowledge of the skin.”


Laser Hair Removal: Permanent or Temporary Fix?

Is it really permanent?

In short, no. Laser hair removal heats the hair follicles to prevent new hair growth. It keeps the hair follicles inactive longer – much longer than shaving and waxing. Hair gets lighter, finer and smaller the bigger it gets.

Although this procedure is often referred to as a form of “permanent” hair removal, laser treatment only reduces the number of unwanted hairs in a specific area. Unwanted hair is not completely removed.

According to the Mayo Clinic, this hair removal option works best on people with lighter skin tones and darker hair. For the best results, the American Association of Dermatologists (AAD) recommends performing the procedure of a board certified dermatologist.

How laser hair removal works

In laser therapy, laser beams with high heat are used as the light form of the radiation. During the process, these laser beams heat up and damage your hair follicles.

The follicles in your hair are just below the skin. You are responsible for producing new strands of hair. When the follicles are destroyed, hair production is temporarily disabled.

Conversely, tweets, shaving, and waxing remove all of the hair on the surface. These methods do not target hair-producing follicles.

AAD considers the following areas to be suitable for laser hair removal:

Bikini line
Face (without eye area)

This form of hair removal works best on darker skin tones in lighter skin tones. Lasers target hair melanin (color) because it is. Even if some hairs cannot be removed, lightening their color can reduce the appearance of hair on the skin.

Some of your first hair loss may occur within a few days of your first treatment.

Overall, laser hair removal is a relatively quick process. Small areas like the upper lip can take a few minutes to complete. Large areas of hair removal, such as the back or chest, can take up to an hour or more.

If your dermatologist applies a topical pain reliever gel (anesthetic) first, you can expect a full hour in the office.

Despite the high success rate of laser hair removal, hair follicles are eventually cured. This leads to the production of new hair. You should have multiple treatment sessions for the best possible results.

Why are follow-up exams required?

Follow-up treatment is required to get the most out of laser hair removal. The exact number of maintenance laser treatments varies from person to person. Most people need four to six laser therapy sessions, according to the Mayo Clinic.

You should also distribute these every six weeks – this means the entire course of treatment can take up to nine months.

You are likely to see less hair after each session. Remaining or regenerated hair is lighter in both texture and color. AAD estimates that by the end of your first session, the number of hairs will decrease by 10 to 25 percent. After that, the rate of decline will improve, but will also vary.

Additionally, you will likely need occasional maintenance sessions for best results and to ensure that the hair follicles are not regenerating. Depending on your individual needs, you may need maintenance sessions once or twice a year after the full first round of laser treatment.

The schedule for each session is the same as the initial laser hair removal treatment. Overall, the timing depends on the treatment area. Your appointment can be shorter if you touch a few small areas during your maintenance session.

Bottom line

While laser hair removal is not exactly permanent, it is one of the best ways to slow down hair speed over a long period of time. Long-term hair removal options that you can discuss with a dermatologist include electronic analysis and needle epilators.

If you don’t want to spend on treatment procedures that aren’t really permanent, there are plenty of home hair removal options.

Talk to your dermatologist:

Twitter epilator
Waxing or sugaring
Correct shaving technique

There are smaller versions of laser hair treatments on the market for home use, but their safety and effectiveness are not clear. The US Food and Drug Administration does not regulate home laser hair treatments as a trusted source as a treatment device, so they are not tested. Better leave laser hair removal to the specialist.
