Shaving, waxing and threading all need repeating every few weeks. Laser hair removal is popular because it gradually reduces the amount of hair growing in a treated area. Here is a plain-language guide to what happens during the treatment and what to prepare for.

How does laser hair removal work?

The laser delivers light energy that is absorbed by the pigment (melanin) in the hair. The energy turns into heat, which damages the hair follicle and reduces its ability to grow new hair. Because only hairs in the active growth phase respond well, and not all follicles are in that phase at the same time, a series of sessions is needed to catch them all.

How many sessions will you need?

The number varies with the body area, hair thickness, hormones and skin tone. Many people need a course of several sessions spaced a few weeks apart, and some need occasional maintenance sessions later. Your specialist can give an estimate after examining the area; results differ between individuals, and laser reduces hair rather than guaranteeing that none will ever grow back.

Who is laser hair removal suited to?

It generally works best on dark, coarse hair. Very light, grey or white hair contains little pigment and responds poorly. Skin tone matters too, since the laser must be matched to the skin so that it targets the hair without harming the skin — so the device and settings used should suit Indian skin tones. A consultation helps check suitability, and the treatment is usually avoided or delayed in some situations, such as during pregnancy, with an active skin infection or tan in the area, or with certain medicines. Tell your specialist about your medical history.

How to prepare

  • Avoid sun exposure and tanning in the area for a few weeks before the session.
  • Do not wax, thread or pluck for several weeks before; these remove the hair root the laser targets. Shave the area the day before or as advised.
  • Come with clean skin, free of creams, perfume or deodorant on the area.
  • Let your specialist know about medicines, skin conditions and any recent peels or other procedures.

What does it feel like?

Most people describe a quick snapping or warm pricking sensation. Comfort varies by area — thicker hair and sensitive areas tend to feel more intense. The skin may look slightly red or have small bumps around the follicles for a few hours afterwards.

Aftercare

  • Avoid direct sun and use sunscreen on exposed areas.
  • For the first day or two avoid hot showers, saunas, heavy workouts, scrubs and perfumed products on the area.
  • Use a soothing, fragrance-free moisturiser if the skin feels dry or tight.
  • Do not wax or pluck between sessions; shaving is usually fine.
  • Hair may seem to shed over the following weeks. This is expected as treated hairs fall out.
  • Contact your clinic if you notice blistering, severe pain or colour changes.

Possible side effects

Temporary redness, mild swelling and sensitivity are the most common. Less commonly there can be changes in skin colour, blistering or burns, particularly if aftercare is not followed or the settings are not right for your skin. That is why the choice of clinic and equipment matters more than the price per session.

Choosing where to get it done

Look for a clinic that examines your skin and hair first, explains the number of sessions and costs, and follows hygiene and aftercare protocols.
