The Ultimate Guide to Laser Hair Removal: What to Expect and How it Works

Laser hair removal, once a novel concept, has steadily topped the ranks in the world of cosmetic procedures, cementing its position as a premier solution for those vexed by unwanted hair. As technology has advanced, this method has garnered a reputation for its efficacy and long-lasting results.

Over the years, countless individuals have said goodbye to traditional, often tedious, hair removal methods like shaving, waxing, and plucking, entrusting their skin to the precision of lasers. If you’ve found yourself on the fence, stumbling between curiosity and uncertainty about this treatment, rest assured, you’re not alone.

This guide aims to shine a light on the intricacies of laser hair removal, offering a clearer perspective on what the procedure involves and setting the stage for what you can expect.

What is Laser Hair Removal?

Laser hair removal is a medical procedure that uses a concentrated beam of light (laser) to remove unwanted hair. The laser emits a light that is absorbed by the pigment (melanin) in the hair. The light energy is then converted into heat, which damages the hair follicles producing the hair. This damage inhibits or delays future hair growth.

Benefits of Laser Hair Removal

  • Precision: Lasers can target dark, coarse hairs while leaving the surrounding skin undamaged.
  • Speed: Each pulse of the laser takes a fraction of a second and can treat many hairs at the same time.
  • Predictability: Most patients experience permanent hair loss after 3 to 7 sessions.

Preparation for the Procedure

It’s not just about zapping unwanted hairs. It’s a medical procedure that requires training to perform and carries potential risks. Before getting laser hair removal, you should:

  • Check the Credentials: Ensure the practitioner has the necessary qualifications and experience.
  • Stay out of the Sun: Sun exposure can make laser hair removal less effective and increases the risk of complications.
  • Avoid Plucking and Waxing: These procedures can disturb the hair follicle and should be avoided for six weeks before treatment.

What to Expect During the Procedure?

  • Protection: You’ll be provided with eye protection to shield your eyes from the laser beam.
  • Skin Test: The technician will test a small area of your skin to ensure there are no adverse reactions.
  • Cooling or Gel: A cooling device or gel will be applied to protect your skin and help the laser penetrate the skin.
  • Laser Activation: The laser will be activated, sending pulses of light to the targeted hair areas.

Now that you have a basic understanding of laser hair removal and its procedure, it’s time to get into some of the nitty-gritty details. Many have questions regarding the long-term effects, the variety of lasers used, and how it feels during the process. Let’s address some of these concerns.

Different Types of Lasers

There are several types of lasers used for hair removal. The most popular ones include:

  • Alexandrite Laser: Best suited for treating larger body areas in patients with a wide range of skin tones.
  • Diode Laser: This is effective for both light and dark skin.
  • Nd:YAG Laser: This laser can be used on all skin types, including tanned skin. It’s less effective for light or fine hair.
  • Ruby Laser: The oldest type of hair-removal laser, it’s best suited for fair-skinned individuals with dark hair.

The right laser for you depends on your skin type, hair colour, and the area of the body you wish to treat.

Pain Management and Comfort

One common question is, “Does laser hair removal hurt?” The sensation is often likened to the snap of a rubber band against the skin. While not entirely painless, the procedure is bearable for most people.

Topical anaesthetics are available to minimise discomfort. Plus, with each subsequent session, as less hair is targeted, the sensation diminishes.

Cost Implications

Laser hair removal isn’t usually covered by insurance because it’s considered a cosmetic procedure. The cost varies based on the size of the area being treated and the number of required sessions. It’s essential to get a clear cost estimate before starting the sessions.

Downtime and Recovery

One of the great things about laser hair removal is that there’s minimal downtime. You can resume regular activities immediately, although it’s best to avoid strenuous exercises for at least 24 hours.

The treated area might appear red and swollen, similar to sunburn, but this subsides within a few hours to a couple of days.

Post-Procedure Care

  • Avoid the Sun: Just as before the treatment, you should avoid direct sun exposure.
  • Use Sunscreen: If you cannot avoid the sun, use a sunscreen with an SPF of at least 30.
  • Expect Skin Changes: Redness and swelling are normal after the procedure. Cold packs and anti-inflammatory creams can help.

Potential Side Effects and Risks

While laser hair removal is generally considered safe, some potential side effects include:

  • Mild redness and swelling
  • Temporary pigment changes
  • Rarely, blistering or scarring


  • Always Consult First: Before committing to laser hair removal, have a consultation with a dermatologist or trained technician to determine if it’s suitable for your skin and hair type.
  • Follow Care Instructions: Post-procedure care is crucial for best results and preventing complications.
  • Be Patient: It takes multiple sessions for complete hair removal. Be consistent with your appointments.

Laser hair removal, while a substantial investment, can offer significant long-term benefits in terms of time saved and boosted self-confidence. It’s always advisable to stay informed and ask questions to ensure the process aligns with your comfort and expectations.

Remember, choosing a qualified and experienced practitioner plays a crucial role in the outcome of the treatment.

FAQs About Laser Hair Removal

1. Is laser hair removal permanent?

While laser hair removal can significantly reduce hair growth, it doesn’t guarantee permanent hair removal. Periodic maintenance treatments might be needed once or twice a year.

2. Are there areas of the body that shouldn’t be treated?

Laser hair removal is versatile and can be done on most parts of the body. The most commonly treated areas are the legs, armpits, upper lip, chin, and bikini line. However, it’s essential to avoid areas around the eyes due to potential eye injury.

3. Can I shave between laser hair removal sessions?

Yes, you can. Shaving is encouraged because it prevents the hair from being visible above the skin’s surface, making the treatment more efficient. However, avoid waxing or plucking as they remove the hair’s root, which is the target of the laser.

4. How long should I wait between sessions?

The waiting period depends on the area being treated. For facial areas, it’s typically 4-6 weeks, while body treatments can be spaced 6-8 weeks apart.

5. What should I do if I experience side effects?

Mild redness and swelling are typical after treatment and usually subside within a few hours. If you experience prolonged redness, blistering, or changes in the skin’s pigment, contact your dermatologist or treatment provider.
