Everyone seems to be getting laser hair removal (LHR) nowadays. While this procedure has been around for a while, after the technology has advanced, it has become more accessible to people. With so many options available for removing unwanted hair, from at-home products to parlour services, it can be hard to sift through the options and decide on what works for you. If you are looking for a long-term solution and want to avoid the hassle of razor burns, pain and ingrown hairs, laser hair removal can be a good choice. Understanding how this technology works can help you decide the best course of action, so you can finally say goodbye to that unwanted hair!

What is Laser Hair Removal (LHR)?
Simply put, the procedure uses a concentrated beam of light or laser to remove hair on different parts of the body. It targets pigment (melanin) found in the hair, and the heat from the laser destroys the hair follicles, preventing them from growing.
Who is a candidate for LHR?
Since the laser is attracted to pigment (colour), this procedure is most effective for people with dark hair and light skin. Patients with darker skin tones usually need to be treated with a different type of laser that differentiates the hair against their skin. One should consult their dermatologist for the best course of action. For people with lighter hairs on their body, LHR may not show very effective results and it does not work for blonde, grey, or white hairs.
Which body parts can you get LHR?
Laser hair removal can be done on any part of the body where there is unwanted hair and both men and women can opt for it. Again, it is most effective on hairs that are darker and coarser, so, body parts like the legs, arms, bikini, and underarms respond well to the treatment. Other popular areas for laser include the face (chin, upper lip, beard), stomach, back and chest.
The results of lasers differ from person to person, for example, if someone has lighter and finer hair on their face, it may be less effective and need more sessions to see hair removal.
How many sessions do you need?
It typically takes 6-12 sessions to see successful and more permanent results. The time between sessions would depend on your hair growth, but a gap of 4-6 weeks is typical. Your dermatologist or technician can usually estimate the number of sessions you will need.
After completing the initial sessions, sometimes you need to have maintenance sessions every year or more to keep the permanent results. Everybody reacts differently to the treatment depending on factors like which area of the body it is, the colour and texture of the hair, any hormonal changes and even the type of laser used.
Are the results permanent?
Compared to the other hair removal procedures available, laser hair removal offers the most long-lasting results. While it significantly reduces hair growth as you get the required sessions, it does not ensure permanent hair removal. Usually, patients who notice their hair growing back after several months or years, note that it is finer and lighter than before.
Does it help with ingrown hairs?
Yes, getting this procedure reduces the chance of getting pesky ingrown hairs that often come with shaving and waxing.
Is it painful?
People report that it is less painful than waxing, but minor discomfort and irritation can occur, especially if you have sensitive skin.
Are there any side effects?
While it is a noninvasive producer, minor side effects can occur. If the side effects linger for long or are very severe, you should consult your dermatologist.
Common side effects
- Redness and irritation: This usually subsides after a few hours of treatment.
- Crusting and dryness: This can be treated with proper post-treatment care like moisturising and protecting the skin from the sun.
- Changes in skin colour: The skin may turn a bit lighter or darker than normal, but it usually fades with time.
Rare side effects
- Burns and blisters: If the procedure is not done by a qualified practitioner, who uses the wrong tools and knowledge, burns can occur. However, if proper procedure is followed, it is very rare.
Is it safe?
The majority of people who undergo laser hair removal find that it is safe and well-tolerated, and there are no long-term health risks.
However, minor side effects can occur and one should discuss their concerns with their dermatologist. It is also important to go to a qualified practitioner or certified dermatologist and a reputable clinic.
