What is laser hair reduction?

Laser hair reduction, also known as laser hair removal, is a popular cosmetic procedure offering a long-term solution for reducing unwanted hair growth. It is a method of using laser light to reduce unwanted hair. It targets the hair roots (follicles) and slows down future hair growth. It's not a one-time fix, but it gives long-lasting results. 

Is it the same as permanent hair removal?

Not exactly. It’s more like *"permanent hair reduction." Over time, hair grows back finer, thinner, and slower — and some may stop growing altogether. But a few maintenance sessions may still be needed.

How does it work?

Laser hair removal works by targeting melanin (pigment) in the hair follicle. The laser’s light is absorbed and converted into heat, damaging the follicle to slow or stop future hair growth. Thanks to selective photothermolysis, the laser precisely targets hair while sparing surrounding skin. Since hair grows in cycles, the treatment is most effective during the active growth phase (anagen), which is why multiple sessions are needed for optimal results.

Is it safe?

Yes, when done by a qualified dermatologist, it’s quite safe. The laser targets only hair, not the surrounding skin.

Does it hurt?

Most people say it feels like a rubber band snap or a mild pinch. Some machines have cooling tips to make it more comfortable. A numbing cream can also be used if needed. So a certified and registered dermatologist with proper equipped machines should be consulted.

How many sessions do I need?

Usually 6 to 8 sessions spaced 4 to 6 weeks apart. Hair grows in cycles, so multiple sessions are needed to catch all hairs during their active phase.

What areas can be treated?

Almost anywhere! Laser hair reduction is often used on delicate areas and the settings are adjusted for each body part. Common areas include,.

• Upper lip

• Chin

• Underarms

• Arms and legs

• Bikini area

• Back or chest (for men)

• Face (for conditions like hirsutism)

Is it safe for all skin tones?

Yes, but the type of laser used may vary. Darker skin needs a laser that's safe and specific for melanin-rich skin to avoid burns or marks. Always go to a certified skin clinic.

What should I avoid before and after treatment?

Pre-Treatment Checklist for Laser Hair Reduction

Here’s what you should do before your laser session to stay safe and get the best results:

• Avoid Waxing or Plucking (4 weeks before)
  Let the roots stay intact — lasers need to “see” the root to target it. You can shave, though.

• Stay Out of the Sun (2 weeks before and after)
  Tanned or sunburned skin is more sensitive to lasers and can lead to side effects. Use SPF 30+ if you're going outside.

• Shave the Area -Shaving reduces the risk of surface burns while keeping the hair root for the laser to work on.

• Avoid Active Skincare Products (like Retinol, AHA/BHA)
  These can make your skin more sensitive. Stop using them on the treatment area a few days before your appointment.

• Don’t Apply Makeup, Deodorant, or Creams on the Day
  Come to your appointment with clean, dry skin. No lotions, perfumes, or deodorants on the area to be treated.

• Let Your Clinic Know About Any Medications
  Some medicines (like antibiotics or acne meds) may increase sun sensitivity. Tell your dermatologist so they can adjust the settings or delay the session if needed.

Post-Treatment Care Guide – What To Do After Laser Hair Reduction

Following your laser session, a little TLC can help you heal comfortably and protect your results.

• Soothe the skin

  • You may feel a sunburn-like warmth or see redness.

  • Apply a cool compress to calm the skin.

• Avoid heat for 24–48 hours

  • Skip hot showers, saunas, steam rooms, and intense workouts.

  • Your skin is temporarily sensitive, so keep things cool and gentle.

• Stay out of the sun

  • Sun exposure can irritate the skin or cause dark spots.

  • Always apply a broad-spectrum sunscreen (SPF 30 or higher) if you go outside.

• Don’t wax, pluck, or bleach

  • Stick to shaving between sessions — it won’t disturb the hair roots.

  • Avoid anything that pulls hair out from the root.

• Skip harsh skincare

  • For a few days, avoid exfoliating scrubs, retinol, acids (AHA/BHA), or active serums on the treated area.

• Let the hair fall out naturally

  • You might see hair "shedding" 1–2 weeks post-treatment — don’t scrub or force it out.

• Keep track of your sessions

  • You’ll need 6–8 treatments spaced a few weeks apart for full results or else as guided by your dermatologist.

  • Consistency is key!

Are there any side effects?

Usually mild — temporary redness, swelling, or a warm feeling for a few hours. Rarely, dark spots or light spots may occur, especially if sun exposure isn’t avoided.

Is it expensive?

It may seem pricey upfront, but in the long run, it saves money on waxing, shaving, and razors and you get smoother skin for longer!

Are You a Good Candidate for Laser Hair Reduction?

Here’s a quick checklist to see if laser might be right for you:

You are a good candidate if:

• You have unwanted hair on areas like face, arms, legs, bikini, chest, or back.

• Your hair is dark enough for the laser to detect (most effective on black or brown hair).

• You are looking for a long-term solution and are okay with multiple sessions.

• You're not currently pregnant or breastfeeding.

• You don’t have skin infections, active rashes, or open wounds in the area to be treated.

• You’re willing to follow sun protection and care instructions.

You may need extra precautions if:

• You have very light blonde, red, or gray hair (less pigment for laser to target).

• You have certain medical conditions or are on medications that increase sun sensitivity.

• You’ve had tanning, chemical peels, or skin treatments recently.

Final thought: Go to a certified and expert dermatologist for such procedures.
