Laser Hair Removal

In recent years, laser hair removal has become a popular option for individuals looking for a long-term solution to unwanted hair. This procedure is convenient and effective for reducing and completely removing hair on various parts of the body.

In this article, we will examine the different types of laser hair removal, how it works, the body areas where it can be applied, session duration and intervals, factors affecting its success, things to consider before and after the procedure, its effects on different skin colors, potential side effects and the permanence of its results. In addition, we will discuss who can undergo laser hair removal and the risks involved.

Different Types of Laser Hair Removal

When it comes to laser hair removal, there are various types of lasers that can be used. These include Alexandrite, Diode, Nd:YAG and IPL (Intense Pulsed Light). Each type of laser has its own advantages and limitations, making it suitable for different skin types and hair colors. Consulting with a qualified professional can help you determine which laser is best for your needs.


Alexandrite is one of the most widely used lasers for laser hair removal. It emits a wavelength of 755 nanometers, which is absorbed by melanin in the hair follicles. This laser is highly effective for people with light to olive skin tones and dark hair. It works by targeting the pigment in the hair follicles, heating and destroying them. The Alexandrite laser is known for its speed and efficiency, making it a popular choice for larger treatment areas such as legs, back and chest.


The diode laser emits a wavelength of 800-810 nanometers, making it suitable for a wider range of skin types. It has a longer wavelength than the Alexandrite laser, allowing it to penetrate deeper into the skin. This makes it effective for people with darker skin tones. The diode laser works by targeting the hair follicles and destroying them with heat. It is known for its precision and ability to selectively target hair follicles while leaving the surrounding skin unharmed.


The Nd:YAG laser is another option for laser hair removal. It emits a wavelength of 1064 nanometers, making it suitable for all skin types, including darker skin tones. This laser has a longer wavelength than both Alexandrite and Diode lasers, allowing it to penetrate even deeper into the skin. The Nd:YAG laser works by targeting the pigment in the hair follicles and destroying them. It is known for its safety and effectiveness, especially for people with darker skin tones or thinner hair.


IPL, or Intense Pulsed Light, is a broad spectrum light source that emits multiple wavelengths. It is not technically a laser, but is widely used for hair removal. IPL works by emitting a series of wavelengths that target melanin in the hair follicles. This causes the hair follicles to heat up and disappear. IPL is suitable for a wide range of skin types and hair colors, but for some people it may not be as effective as laser treatments.

How Does Laser Hair Removal Work?

The laser used in this procedure is specifically designed to target the melanin or pigment in the hair follicles. Melanin is responsible for giving hair its color and it is this pigment that absorbs the laser energy.

Once the laser energy is absorbed, it is converted into heat. This heat then travels down the hair shaft and into the hair follicle, where it damages the cells responsible for hair growth. By damaging these cells, laser hair removal effectively inhibits future hair growth in the treated area.

One of the most important advantages of laser hair removal is its precision. The laser can selectively target the hair follicles without affecting the surrounding skin. This is because the laser is attracted to the pigment in the hair follicles and can distinguish between melanin in the hair and melanin in the skin.

It is important to note that laser hair removal is most effective on dark, coarse hair. This is because the laser energy is better absorbed by the melanin in dark hairs, allowing more efficient heat transfer to the hair follicles. However, advances in laser technology have made it possible to treat a wider range of hair colors and skin types.

How is it Applied?

During a laser hair removal session, the esthetician will use a hand-held device to deliver laser energy to the targeted area. The sensation experienced can vary from person to person, some describe it as mild discomfort or a slight stinging sensation. Cooling devices or numbing creams may be used to minimize any discomfort.

It is important to remember that laser hair removal is not a one-off treatment. Multiple sessions are usually required to achieve the best results. This is because hair grows in cycles and laser hair removal is most effective when the hair follicles are in the active growth phase. The number of sessions needed can vary depending on factors such as the person’s hair type, skin color and the area being treated.

Which Body Areas Can Laser Hair Removal Be Applied?

Laser hair removal, facial area, arms, legs, armpits, bikini area, back and chest
can be applied on various body parts.

  • Face Area: One of the most common areas for laser hair removal is the face. Many people, especially women, struggle with unwanted facial hair, which can be a source of embarrassment and self-consciousness. Laser hair removal offers a safe and effective solution to target and eliminate facial hair, including the upper lip, chin and sideburns.
  • Leg Area: When it comes to the body, laser hair removal can be performed on various areas. The legs, for example, are a popular treatment area, especially during the summer months or for those who want to enjoy smooth, hair-free skin all year round. Targeting the hair follicles on the legs, laser hair removal can provide long-lasting results, reducing the need for constant shaving or waxing.
  • Armpits: Another area where laser hair removal can make a significant difference is the underarms. Many people struggle with dark and coarse underarm hair, which can be particularly uncomfortable and difficult to manage. With laser hair removal, individuals can say goodbye to daily shaving or painful waxing and enjoy the freedom of hair-free underarms.
  • Bikini Line: It can effectively target and eliminate unwanted hair in the bikini area, including the bikini line, pubic area and even the buttocks.
  • Back and Chest Area: Laser hair removal can also be performed on larger areas of the body, such as the back and chest.

Duration and Intervals of Laser Hair Removal Sessions

The duration of a laser hair removal session can vary depending on the size of the treatment area. Smaller areas such as the upper lip or underarms can take as little as a few minutes, while larger areas such as the legs or back can take up to an hour. The intervals between sessions typically range from four to six weeks, which allows enough time for the hair to regrow and be effectively targeted in subsequent sessions.

Factors Affecting the Success of Laser Hair Removal

The success of laser hair removal can be influenced by several factors. One important consideration is the contrast between hair color and skin tone. Typically, people with fair skin and dark hair are the best candidates, as the laser can target dark pigment more easily. Other factors include hair thickness, hair growth cycle and hormonal changes. Discussing these factors with a professional can help determine the likelihood of successful results.

Things to Consider Before and After Laser Hair Removal

There are a few important things to keep in mind before having laser hair removal. It is very important to avoid sun exposure, tanning beds or any form of self-tanning before the treatment to reduce the risk of complications. After the procedure, it is very important to follow the aftercare instructions provided by the technician, such as avoiding excessive heat, sun exposure and certain skin care products. By following these guidelines, you can optimize your results and minimize possible side effects.

Skin Color in Laser Hair Removal

The effectiveness and safety of laser hair removal can vary according to skin color. While individuals with fairer skin and darker hair tend to respond best to treatment, advances in laser technology have made it possible for individuals with darker skin tones to achieve successful results. However, it is very important to consult with an experienced professional who can customize the treatment to your skin color and hair type.

Are There Side Effects of Laser Hair Removal?

As with any medical procedure, laser hair removal has potential side effects. These may include temporary skin irritation, redness or swelling in the treated area. In rare cases, blistering or changes in skin pigmentation may occur. However, these side effects are usually temporary and subside within a few days or weeks. It is important to discuss any concerns or pre-existing conditions with your provider before starting treatment.

Is There Any Harm in Laser Hair Removal?

When performed by a skilled professional, laser hair removal is generally considered safe. However, it is very important to make sure that the procedure is performed by a trained technician using approved equipment. Proper eye protection should also be provided to guard against the intense light of the laser. Consulting a reputable clinic and verifying credentials can help minimize any potential risk of harm.

Are Laser Hair Removal Results Permanent?

Laser hair removal offers long-lasting results, but it is important to understand that it may not completely eliminate hair growth. Most people experience a significant reduction in hair density and some areas become almost hairless. However, occasional touch-up sessions may be required to maintain the desired results. The permanence of the result can vary from person to person and may depend on factors such as hormonal changes or stimulation of new hair follicles.

Who Can Have Laser Hair Removal?

Almost anyone can have laser hair removal, but some factors may limit its effectiveness or suitability for individuals. Pregnant women, people with certain medical conditions, or those taking certain medications may need to avoid laser hair removal. Consulting with a healthcare professional or licensed technician will provide personalized guidance based on your specific circumstances.

In conclusion, laser hair removal offers a convenient and effective solution for individuals seeking permanent hair reduction. By understanding the different types of lasers used, the mechanics of the procedure and the important factors that influence its success, one can make informed decisions about undergoing treatment.

Taking the necessary precautions before and after treatment, considering skin color and being aware of potential side effects and risks are vital for a positive experience. Overall, laser hair removal has proven to be a valuable option for achieving smooth, hair-free skin and provides individuals with greater confidence and ease in their daily lives.
