Laser Hair Removal

Laser hair removal is a medical technique that removes unwanted hair using a focused beam of light (laser). A laser emits a light that is absorbed by the pigment (melanin) in the hair during laser hair removal.

The light energy is transformed to heat, which destroys the hair follicles, which are tube-shaped sacs within the epidermis that generate hairs. Hair growth is inhibited or delayed as a result of this injury.

Everything about Laser Hair Removal

Laser hair removal is a medical technique that employs a light beam to eliminate the hair that is not desired.

A laser is absorbed by the hair pigment (melanin) into the hair during laser disposal. Light energy has been transformed to heat, causing damage to hair follicles (tube-shaped bags in the skin). The damage prevents or retards the development of subsequent hair.

Although laser hair elimination successfully slows hair development over lengthy periods, there is no permanent eradication of hair. For the initial elimination of hair, several laser hair removal treatments are required. Maintenance treatments may also be required. People with light skin and dark hair benefit the most from laser hair removal, although it may be used on people of all skin types.

Yes, laser hair removal is well worth the investment. It is a cutting-edge hair removal procedure that is one of the most popular aesthetic treatments. Blondes are the only ones that have problems with laser hair removal. Laser hair removal is unsuccessful for persons with blonde, white, or grey body hair.

In a word, no. Laser hair removal works by heating hair follicles and preventing new hair growth. Even though laser therapy is typically marketed as a kind of permanent hair removal, it merely decreases the number of undesirable hairs in a specific region. It doesn’t fully remove undesirable hairs.

To get the most out of laser hair removal, you’ll need to have follow-up sessions. The number of maintenance laser treatments required varies from person to person. It is estimated that most patients will require four to six laser treatment sessions. You must also space them out by six weeks apiece, making the entire therapy cycle take up to nine months. You’ll probably see fewer hairs after each session. Any hair that survives or grows back will be lighter in structure and color. After your first session, the AAD predicts that the number of hairs will decrease by 10% to 25%. Following that, the pace of decrease will improve, but it will also fluctuate. You’ll also need to schedule maintenance sessions from time to time for the greatest effects. These aid in the prevention of hair follicle regeneration. After your entire initial round of laser treatment, you may require a maintenance session once or twice a year, depending on your specific needs. Each session follows the same timetable as your original laser hair removal procedure. In general, the duration of treatment is determined by the treatment area. Your visit may be cut short if you’re only touching up a few minor spots throughout your maintenance appointments.

Hair will not grow longer if you discontinue laser hair removal after two sessions since the hair that was removed is completely gone. The aesthetic effects, however, will be affected by the exact procedure used. If you apply it in portions (as you could in a huge region like the back), you’ll see that one area will be hairless, while the other will continue to develop hair.

The final cost of laser hair removal is determined by several factors. These factors include the number of sessions, the equipment utilized, the color of the hair, and the facility’s pricing policy. One thing is certain: you will require numerous treatments, ranging from 5-8 sessions depending on the region and duration of the development cycle. Small regions, such as the underarms and chin, can be relatively inexpensive to treat. Other regions, such as complete legs, might be extremely costly. There are sessions available for as low as $30 and as much as $500 approx.

Long-term consequences of laser treatment have not been explored, including the potential for increased cancer risk. Some investigators noted alterations in atypical moles (dysplastic nevi) following the removal of laser hair. They thus recommend that patients with a personal or family history of skin cancer or atypical moles should be given care while using cosmetic laser treatment until additional study confirms whether or not such alterations are malignant.

Though laser hair removal is safe, there is a risk associated with all laser treatments. An expert health care practitioner will evaluate if you're a good candidate and utilize the optimal laser settings for your skin. There is always the risk of burning, hyper or hypo-pigmentation, blistering, scarring, and, in rare circumstances, hair development in the treated region, even with the finest preparation, expertise, and experience.

Laser hair removal is a common cosmetic surgery used to permanently remove unwanted hair. It works by preventing hair follicles from generating new hair strands for a short period. While laser hair removal isn’t fully permanent, the effects might linger for many weeks. This therapy may also be beneficial for hard-to-shave or wax regions of the body. Even yet, the advantages of laser hair removal cannot be realized without some discomfort. The therapy may be uncomfortable, depending on the region being treated and your pain tolerance. Talk with your doctor about any concerns you have.

Even though laser hair removal is the quickest, safest, and most pleasant method of hair removal accessible today, several fallacies prevent individuals from getting it done.

  • Hair will be removed on the first session using laser hair removal

Isn’t this just too wonderful to be true? Because hair grows in cycles, it is necessary to undergo 6-8 Laser Hair Removal sessions before seeing long-term benefits. Even so, there is no assurance that the treatment will last forever. Long-term hair growth can be influenced by hormones and genetics, however, Laser Hair Removal can significantly reduce hair growth.

  • Scarring can occur as a result of laser hair removal

Any laser therapy carries a minor risk of scarring, which is listed as a risk on our consent papers that are completed before laser treatment. However, the risk of scarring following laser hair removal is low and depends on several factors, including the clinician’s experience, competence, knowledge, and training, your capacity to recover, the quantity of pigment in your skin (darker skin types are at higher risk), and the kind of laser utilized.

  • Hair growth can be increased by laser hair removal

If this was true, baldness would be a thing of the past! Lasers can’t make hair grow faster, but it’s vital to remember that our bodies are continuously changing, and some people will lose body hair as they age while others will develop more in new areas. Hair follicles can be destroyed by laser, but new ones cannot form.

  • All hair types respond to laser hair removal in the same way

A consultation with the doctors is required to establish whether your hair type is appropriate for Laser Hair Removal. Hair color, skin type, and individual differences all influence the outcome. Red hair is harder to remove (though not impossible). White and grey hair cannot be eliminated with laser therapy because they lack the pigment that the laser needs to be attracted to; hence, the lasers are unable to detect and destroy the hair follicles.

  • You are exposed to radiation when you have laser hair removal

Some clinics employ lasers to treat patients without exposing them to radiation. While there is radiation in the region between the laser’s light barriers, it does not leave that space and is therefore harmless to the laser hair removal receiver.

  • Ingrown hairs are a side effect of laser hair removal

The exact reverse is true! After shaving and waxing, ingrown hairs are a typical irritation, but not after laser hair removal. In reality, laser hair removal lowers the risks of ingrown hairs by destroying the hair follicle, which effectively kills the ingrown hair.

  • It is painful to use laser hair removal

Waxing is more painful for most people because it tugs on the skin. Some individuals have compared Laser Hair Removal to flicking an elastic band, which is a popular comparison. A topical anesthetic is offered for people who find the treatment to be unpleasant.

When contemplating laser hair removal, one of the most common questions is which regions may be treated. Laser hair removal is mild enough to be utilized on delicate regions of the body while yet being very effective. Traditionally, laser hair removal has been used on the following parts of the body:

- Face (upper lip, chin, and sideburns)

- Underarms

- Back

- Legs

- Area of bikini

- Brazilian (can include the labia)

Patients with persistent hair growth in other areas of the body, such as the toes, stomach, and buttocks, might benefit from laser hair removal.


You should consider laser hair removal, if:

- You have undesirable face or body hair that makes you feel self-conscious or prevents you from wearing certain types of clothing

- You have pale skin and black hair

- You’re seeking a non-waxing, non-electrolysis, non-shaving, non-bleaching alternative to waxing, electrolysis, and shaving

Hair follicles, which are tiny spaces in the skin from which hair develops, are affected by focused light in laser hair removal. The laser absorbs the hair follicle, which is drawn to the melanin pigment in the hair, and the hair vaporizes instantaneously. The light energy is converted to heat, which destroys the hair-producing hair follicles (tube-shaped sacs inside the epidermis). Future hair development is slowed or stopped as a result of the damage.

Darker hair absorbs the laser more efficiently because the pigment in the hair attracts the laser, which is why persons with dark hair and light complexion are good candidates for laser hair removal.

Patients with dark skin generally require treatment with a laser that identifies the hair against their skin.

Those who have light hair are less suitable and they will also have less chance of dramatic effects because the laser is not focused on unpigmented hair. Laser hair removal on blonde, grey, or white hair is not effective.


Choose a specialist who is board certified in a specialty such as dermatology or cosmetic surgery who has expertise with laser hair removal on your skin type if you’re interested in laser hair removal. If the operation will be performed by a physician assistant or a licensed nurse, ensure a doctor oversees the process and is present on-site during the therapy. 

The elimination of laser hair is not only zapping undesirable hair. Therefore, it is a treatment that needs expertise and involves possible dangers. You should extensively examine the doctor or technician’s credentials before having laser hair removal. Avoid spas, salons, and other establishments that allow non-medical staff to perform laser hair removal.

You should restrict plucking or waxing and electrolysis to six weeks before treatment if you want to undergo laser hair removal. The laser targets the roots of the hair that are removed momentarily by waxing or plucking.

Sun exposure should be avoided for six weeks before and after therapy. When exposed to the sun, laser hair removal becomes less effective, and complications are more likely to occur.


Laser air removal has both pros and cons.

Pros of laser hair removal

Laser hair removal has several advantages.

  • Precision

Lasers may target dark, coarse hairs selectively while causing no harm to the surrounding skin.

  • Speed 

The laser pulses are only a fraction of a second long and may treat a large number of hairs at once. A quarter-sized region may be treated every second by the laser. Small regions, like the upper lip, can be treated in under a minute, while big areas, like the back or legs, might take up to an hour.

  • Predictability 

After three to seven treatments, the majority of patients lose their hair permanently.

Cons of laser hair removal

The hair color, treatment, and adhesion therapies to pre and post-treatment care will differ in the risk of adverse effects. The following are the most frequent laser hair removal adverse effects:

  • Skin irritation

Laser hair removal can cause temporary pain, redness, and mama. After a few hours, all signs and symptoms should go.

  • Changes in pigmentation 

As a result of laser hair removal, the affected skin may darken or lighten. These changes might be transient or permanent. Those who do not prevent sun exposure before or after treatment, as well as those with darker skin, are most affected by skin whitening.

  • It’s a lengthy procedure

It takes less than a minute for laser hair removal on the underarms. However, genuine benefits take many sessions (three to eight, depending on the size of the region), and you must wait at least six weeks between treatments.

  • Costs a lot of money

When you consider how much you’ve spent on razors and bikini wax procedures throughout your life, laser hair removal may be worth the $200-$400 approx. for each session. Laser hair removal might be viewed as a worthwhile investment in one's appearance.

Blisters, crusting, scarring, or other changes in skin texture are rare side effects of laser hair removal. Greying of treated hair or excessive hair growth surrounding treated regions, especially in those with a darker complexion, are other uncommon adverse effects.

Because of the risk of serious eye damage, laser hair removal is not suggested for the eyelids, brows, or adjacent regions.

Laser hair removal is a time-consuming technique. To completely halt hair growth, these treatments require repeated sessions. This might also involve certain after-session procedures. Following are some pointers for aftercare:

  • Avoid Showers/Saunas 

Heat is used to kill hair follicles in laser therapy. As a result, applying too much heat to the treated region can irritate it. As a result, while you’re being treated, stay away from hot showers and saunas.

  • Avoid hard workouts 

Raising your body temperature, on the other hand, might be counterproductive. It is recommended not to engage in any intense activity for the next 48 hours following each session.

  • After each session, avoid the sun for a week 

UVA and UVB radiation from the sun might irritate the treated region. As a result, it is recommended that you stay out of the sun for at least a week following each session. If you’re going out, make sure you’ve dressed appropriately, and if you’ve had a facial treatment, use a hat or scarf to keep the sun off your face. Another option is to liberally apply sunscreen with an SPF of at least 30 to the affected region.

  • Avoid harsh skin products and cosmetics 

Your skin will still be susceptible following the treatment. Using strong chemicals on your skin, particularly on your face, can irritate you. Following each treatment, wait at least 24 hours before applying makeup.

What to expect during Laser Hair Removal

Two to six laser hair removal sessions are generally required. The time between treatments will differ based on where you are. The treatment may be repeated in four to eight weeks in places where hair grows fast, such as the upper lip. The treatment may be repeated every 12 to 16 weeks for regions with poor hair growth, such as the back.

During the procedure: Your hair that will be treated will be cut to a few millimeters above the skin surface just before the operation. To aid alleviate the sting of the laser pulses, a topical numbing medication is usually given 20- 30 minutes before the laser operation. The laser equipment will be calibrated to match the color, thickness, and position of the hair you're having removed, as well as the color of your skin.

You and the technician will need to wear proper eye protection depending on the laser or light source utilized. It will also be required to use a cold gel or a specific cooling gadget to protect the outer layers of your skin. This will aid in the penetration of the laser light into the skin.

The technician will then apply a pulse of light to the treatment region and monitor it for several minutes to ensure that the optimal settings were applied and that no adverse responses occurred.

You may be given ice packs, anti-inflammatory creams or lotions, or cold water to relieve any discomfort following the operation. After four to six weeks, you can arrange your next treatment. Treatments will be given until your hair stops growing.
