Part 1: What is Laser Hair Removal?

How Laser Hair Removal Works?

Laser hair removal works on the technology of selective thermo photolysis and extended selective photothermolysis. In the former, the melanin of the hair absorbs high-intensity light radiation from the laser machine and these are converted into heat at the level of hair follicles destroying them.

In the latter, the radiations are transmitted from one hair follicle to the other under the surface of the skin, resulting in damage to the follicles  [1]. Therefore, lasers are a non-invasive procedure for
long-lasting hair removal  [2].

Laser Hair Removal Before and After:

Laser hair removal treatments start when a laser surgeon declares you a suitable candidate for this procedure.
In the past, people with dark hair and light skin tones were considered the ideal candidates for laser [3]. But now the technology has advanced to help light hair colors and
dark skin tones as well.

Furthermore, the laser is not a one-time procedure. Rather it consists of 6 to 12 sessions as the light needs to
capture the hair in the anagen phase for it to be efficient [4]. There is a time interval of 4 to 6 weeks between subsequent
sessions. You can see the results after 4 and 6 sessions in the image given below.

A study carried out in 59 women of Indian origin shows the improving results of laser hair removal in successive
sessions [5]. It demonstrates that the hair is reduced by 23-33% after 1 session,
58-62% after 3 sessions, and 50-100% after 7 sessions.

Additionally, it is important to note that lasers are safer and more effective when you follow proper aftercare of laser hair
removal.

Laser Hair Removal Vs. Electrolysis Vs. IPL Hair Removal:

Laser hair removal is a professional method in which a doctor will help you deal with unnecessary hair using a
precise and targeted hair removal machine. It is safe, kills hair follicles effectively, and lasts for a few
years. However, lasers can be painful and expensive.

Electrolysis is the only FDA-cleared method of
hair removal that lasts forever [6]. It is a long-lasting method in which a small wire is
passed into the skin to annihilate the hair follicle with an electric current and make it unable to produce hair
ever again. Although long-lasting, electrolysis is time-consuming and extremely painful.

Then comes IPL hair removal as the most practical, less
painful, convenient, and cost-effective method of semi-long-lasting hair removal. IPL uses thermo photolysis
technology similar to lasers but with a broad spectrum of light. The only con of IPL is that it is not as
precise and as long-lasting as a laser.

Regarding electrolysis
vs. laser hair removal, the laser is considered as more of a practical method [7].

Is Laser Hair Removal Long-lasting?

Unfortunately, laser hair removal is not a long-lasting method. It is effective for many months to a few years. But
unwanted hair always finds its way back by regenerating. The outcome of laser hair removal studied in an article
shows that regular touch-ups are necessary to maintain hairlessness even after you are completely done with the
treatment [8].

Part 2: Benefits and Side Effects of Laser Hair Removal

Benefits of Laser Hair Removal:

The advantages of in-salon laser hair removal are given as:

• Safe: Laser is a safe method of hair removal as it only affects the hair follicle while
  keeping the skin intact.
• Effective: Laser is effective for most skin tones and most hair colors as long as the
  right type of laser is used [9].
• Accurate: Although laser hair removal is a great choice for large areas, the small
  window of laser probes helps in precisely grooming the hair on small areas like eyebrows, bikini lines,
  and pubic areas as well.
• Fast: The laser flashes fast dealing with several hair follicles at one time. So, you
  only need to spend 30 to 60 minutes in each session of your treatment.
• Semi-long-lasting: In contrast to the hair removal methods that last for a week or two,
  laser hair removal lasts for months or years.
• Treats ingrown hair and strawberry legs: Once you get laser, you never have to worry
  about ingrown hair and strawberry legs because the laser has killed the follicles that result in such
  side effects.
• Cost-saving in the long term: Lasers might seem expensive at first, but you never have
  to pay for waxing, epilation, and at-home hair removal tools. This helps you save the money spent on
  grooming the hair.
• This can be done on any part: Laser hair removal eliminates the hair on all parts of
  the body and face.

Safety and Risk of Laser Hair Removal:

When you are just considering getting laser hair removal, it is normal to get concerned about the safety as the
laser might cause harm. Let us tell you that laser is safe and only has a few reversible side effects as long as
you choose a skilled professional and a reputable clinic.

The common side effects of laser include:

• Transient pain during the session
• Skin redness, irritation, and swelling immediately after the session
• Temporary skin pigmentation in dark skin people
• Rarely, skin burns, blisters, and scars if the laser is not done right

Can Laser Hair Removal Cause Cancer? And Is Laser Hair Removal Safe?

No, laser hair removal cannot cause cancer. You might want to avoid lasers if you have active cancer or a
history of malignancy. But the laser is completely safe for healthy skin as the UV radiations used in the laser
have a wavelength that does not fall in the range of the rays that can potentially cause cancer.

Furthermore, a study carried out to determine the relation of  IPL and laser with carcinogenicity concluded that
lasers cannot cause cancer  [10].

Does Laser Hair Removal Hurt?

Well, most clinics say lasers are nearly painless or only cause a little discomfort. But sadly, it is not true. Laser
hurts and the intensity of this hurt varies with your pain tolerance. For some people, it is like a rubber band
snapping sensation. For others, it feels like a honey bee stinging. Also, you can take painkillers 30 minutes
before the session to reduce discomfort.

Can You Get Laser Hair Removal While Pregnant?

There is limited data on the safety or side effects of laser hair removal in pregnancy. While no studies have
shown that a laser caused any harm to the mother or baby, there were only a few studies to show that it caused
no harm at all. Therefore, better safe than sorry. So, it is best to avoid lasers while pregnant [11].

Part 3: How Much Does Laser Hair Removal Cost?

Factors Determining the Cost of Laser Hair Removal:

The cost of laser hair removal is determined by several factors given below.

Treatment area:

The greater the area of the treatment, the greater will be the cost. For example, laser hair removal on the face costs less than on the legs.

Number of sessions needed:

Laser generally requires 3 to 6 sessions to be effective. You can get more than that depending on the density of
the hair and the results you want. As you have to pay for laser per session, the more the number of sessions,
the more will be the cost.

Expertise of the clinic:

If you opt for a famous clinic with advanced technology and highly-educated laser hair removal expert, you will be charged more than an average clinic with an average clinician. But remember that more fame does not mean better results.

Geographical location:

Laser hair removal in big cities like New York costs much more than in small cities or the countryside like
Houghton. Also, do not forget to add the commute cost when you estimate the total fee of a clinic depending upon
its geographical location.

Promotions and discounts:

Sometimes clinics offer discounts in a specific season, their anniversary, or national occasions. These
promotions can reduce the overall cost of lasers.

Laser Hair Removal for Different Parts of the Body:

According to the American Society of Laser Surgeons, the average price of 1 laser session without additional expenses was $389 in 2020 [12]. A breakdown of the laser hair removal sessions for different body parts is given below.

Potential Value Cost Effectiveness of Laser Hair Removal:

An average session of waxing at a salon costs around $200 for the full body. You have to get the treatment every
month. Also, if you buy a waxing kit, it will cost you around $50 a month. If we compare the long-term price of
waxing with laser, it is clear that laser hair removal is more cost-effective.

Also, let us remember how mess-free it is. And you can also avoid all side effects of waxing and shaving in
laser hair removal along with saving your time.

Does Insurance Cover Laser Hair Removal?

Laser hair removal is an aesthetic and cosmetic procedure. So, insurance does not cover it. However, in some
cases like pilonidal sinus disease, teratoma, and hidradenitis suppurativa, it is a medical procedure.
Therefore, insurance might be able to help you here.

Part 4: Laser Hair Removal Process

How to Prepare for Laser Hair Removal?

In-salon lasers need adequate preparation so that you get optimal results and the side effects are minimal. So,
take the following measures to prepare yourself for lasers.

• Start wearing sunblock every day whether you are staying indoors or going out. Also, reapply it
  depending on the time spent in direct sunlight. Sunlight sensitizes the skin and makes it prone to being
  burnt by the UV rays of the laser.
• Quit your artificial tanning treatments. Because the laser works best on light skin tones and can damage
  tanned skin.
• Stop using active skincare products like retinol and chemical exfoliants. Rather focus on the products
  that heal the skin and strengthen its barrier.
• Just before the procedure, cleanse your skin well and ensure that the treatment area contains no
  perfume, deodorant, lotion, or impurities.
• Do not pluck the hair from the roots by waxing, tweezing, or other methods. Also, do not use depilatory
  creams at least 2 weeks before your session.
• Shave your hair freshly before going for your session. It is because the laser needs hair strands to go
  to the follicles. But this strand must not be too long as it can be burnt along with harming the skin
  without reaching the roots.
• Furthermore, always talk to your doctor about any skin condition you have and any medicines you are
  taking so that your treatment can be customized accordingly.

General Process for Laser Hair Removal in the Clinic:

The process of laser hair removal begins with your consultation. The consultation includes a discussion about
your skin condition, medications, expectations, number of sessions required, and any particular information you
like to know. The doctor also sets your treatment schedule.

On the day of the treat, go to the clinic with clean and shaved skin. Also, take painkillers if your pain
threshold is low. The doctor applies an anesthetic gel over the treatment area and then starts flashing the
laser probe over the skin. Each flash gives out a beep and your skin feels as if something is stinging it.

After the session, you need to wear loose clothes, protect your skin from the sun, avoid hot showers and
sweating, and avoid exfoliation for 2 days as well.

How Many Sessions of Laser Hair Removal Do You Need?

The sessions of laser hair removal are variable. You need a minimum of 3 sessions to notice significant results.
The complete treatment, however, requires 6 to 12 sessions depending on the hair color, thickness, and density.

Do I Shave Before Laser Hair Removal?

Yes, you should shave before laser hair removal. Shaving trims the hair to an adequate length for the laser to
be effective while keeping the skin intact.

Can I Get Laser Hair Removal Over a Tattoo?

No, you cannot get laser hair removal over a tattoo. It is because a tattoo is a hyperpigmented area of the skin
that tends to absorb a greater amount of the rays. The rays distort the skin, might burn it, and cause blisters.

Also, some lasers work for dark skin. However artificial tattoos make it challenging for such lasers to leave
the skin intact as well. This is because the color of the hair resembles that of the tattoo.

How Long Does Laser Hair Removal Last?

According to the American Academy of Dermatology Association, laser hair removal lasts for months to years [13]. Laser either puts the hair in a dormant phase or destroys its
follicles. The follicle that is destroyed might regenerate after a few years. And the hair that is in the
dormant phase can become activated at any time.

As a result, the results of laser hair removal last for a few months to a few years. Also, remember that you
will have to get 1 to 2 touchups during this time as well.

Part 5: Post-Treatment Care for Laser Hair Removal

Post-Treatment Instructions to Get Optimal Results:

Here are some post-treatment care tips for laser hair removal.

• Wear loose clothes for 1 to 2 days after the laser to reduce skin friction.
• Do not wear deodorant, perfume, or lotion for 24 hours.
• Use aloe vera gel to soothe the skin.
• You can try cold compresses to reduce skin redness and pain.
• If your doctor has prescribed any medicine, use it according to the instructions.
• Avoid chemical-containing makeup and try using gentle mineral makeup until your skin is healed after the
  session.
• Avoid hot baths, swimming, and steam for 2 days.
• Do not pluck or wax the skin. Rather shave the hair that regrows back exclusively.
• Use gentle cleansers, moisturizers, serums, and creams to speed up skin healing.
• Exfoliate the skin after 2 days to help the hair shed from the roots.
• Lastly, the most important thing is to avoid sun exposure and wear sunscreen. Also, avoid artificial
  tanner for 1 to 2 weeks after the treatment.

Side Effects and Ways to Prevent and Treat Them:

The side effects of lasers are temporary and can heal on their own. However, if you want to manage them quickly,
here are some tips.

• Pain: Pain caused by laser can be avoided by taking painkillers like ibuprofen and
  asking your doctor to prescribe some topical pain-reducing gels.
• Redness and swelling: These are the common side effects of laser hair removal that can
  be managed by using cold compresses for 10 to 20 minutes a few times.
• Itching and irritation: Using a soothing moisturizer or aloe vera gel can reduce
  irritation.

How to Stop Itching After Laser Hair Removal?

Cold compresses and over-the-counter creams like Sudocrem can help you stop itching after laser hair removal.
Furthermore, using enriched yet gentle body and facial lotions can soothe the itching.

Can I Shave After Laser Hair Removal?

Of course, you can shave after laser hair removal. Rather you should exclusively shave the skin in between your
laser sessions. However, do not shave immediately after the session, wait for 3 to 5 days, and allow the hair to
regrow.

Can I Work Out After Laser Hair Removal?

Yes, you can work out after laser hair removal. However, you cannot work out immediately after laser hair
removal. This is because a workout makes you sweat and your body hot which increases skin redness and
inflammation. So, wait for 1 to 2 days after your session to begin your exercise routine.

Part 6: At-Home Laser Hair Removal

At-home laser hair removal devices can be used as a reliable alternative to in-salon laser hair removal
treatments when you do not want to spend too much money on the treatment or cannot spare enough time to get it.

Benefits of At-Home Laser Hair Removal Devices:

Here are some of the top advantages of at-home laser hair removal devices.

• Safe and efficient: Most at-home laser hair removal devices are safe to use at home
  with no expert guidance. Moreover, IPL devices are faster and more efficient.
• Minimal preparation and post-treatment care: In contrast to laser where you have to
  fully prepare yourself, you only need to protect yourself from the sun avoid harsh products, and shave
  for the at-home laser treatment. Also, there is no need to take painkillers as these treatments are
  nearly painless.
• Affordable and durable: A good IPL device costs $300 to $600 and comes with flashes
  that last for 25 to 50 years making them both durable and cost-effective.
• Easy followups: As you always have an at-home laser hair removal device at hand, you
  can treat unwanted hair at any time as per requirement.
• Effective for full body and hair: At-home laser hair removal devices are legitimate and
  useful for hair removal on the full body and face as concluded by a study [14].

Part 7: Laser Hair Removal for Dark Skin

Suitable Skin Tones for Laser Hair Removal:

Until a few years ago, laser hair removal was only suitable for light skin tones ranging from Fitzpatrick score
I to III. However, the technology developed recently like the Diode laser made it possible for darker skin tones
like type IV [15]. Therefore, laser is now suitable for everyone as long as the right
technology is chosen.

Advanced Laser Technology for Dark Skin:

The long wavelength of Nd: Yag, Diode, and Alexandrite can be safely used for dark skin tones. Among all of
these, Nd: Yag is considered the safest and most effective option [16].
This is because it can penetrate the hair follicles without disrupting the dark epidermis.

Also, it is important to carefully choose the device and wavelength that would be used on the dark skin. Because
the wrong type of laser can result in laser burns of the skin, blisters, crusts, pigmented sections, and
scarring. You should always have a patch test done to ensure that the laser is suitable for your skin tone.

Benefits of Laser Hair Removal for Dark Skin:

Just like laser hair removal is beneficial for other skin types, dark people can also get the best of it. So,
here are some of the benefits of laser hair removal for dark skin tones.

• Safe hair removal when the right wavelength of the laser is used
• Effective hair removal as laser destroys the follicle without harming the skin
• Hair removal that lasts for a few years as hair roots are destroyed
• Reduced risk of ingrown hair and strawberry legs
• Cost-effective considering the price of other hair removal methods
• Better skin texture

Limitations of Laser Hair Removal for Dark Skin:

The laser that uses a shorter wavelength than 600 nm is not suitable for dark skin. This is because such
wavelengths can only target the pigment without realizing if the pigment is in the skin or the hair [17]. Therefore, it gets absorbed into the skin causing damage.

Conclusion

Even if the laser seems like the best solution to the frustration you get because of regular waxing, shaving,
and whatever, it is always a wise move to get informed about the laser before deciding to go for the treatment.

Laser hair removal offers long-lasting results. But the treatment is also expensive and painful. It might also
not be suitable for your skin or health condition. Therefore, we discussed how lasers can be useful and harmful
to you.

Always get a consultation and talk to your doctor in detail before signing up for the treatment. Lastly, we hope
this article answers most of your queries about laser hair removal.
