Laser hair reduction uses light energy to damage the hair root so that hair grows back finer and sparser. It usually needs a course of sessions, it reduces hair rather than removing it for good, and for many women it depends on whether a hormonal cause is also being looked at.
Here is what women most often want to know before starting.
How does laser hair reduction work?
The pigment in the hair absorbs the laser's light and turns it into heat, which damages the follicle. This works best when there is a clear contrast between the hair and the skin, so dark, coarse hair responds well, while very fine, light or grey hair responds poorly.
The laser can only affect hairs in their active growth phase, and only some hairs are in that phase at any one time. That is why one session is never enough.
How many sessions will I need?
Many women need around six to eight sessions, usually spaced several weeks apart. The gap is often shorter on the face and longer on the body. The exact number varies with the area, hair type, skin tone and hormones, so it should be agreed after an assessment. Some maintenance sessions may be needed later.
Is it permanent?
"Reduction" is the honest word. Much of the hair may not return, and what grows back is usually finer and lighter, but this is not the same as removing every hair for good. Results differ from person to person.
Why does facial hair keep coming back in some women?
Coarse hair on the chin, upper lip or neck in women is often linked to hormones, and PCOD is a common reason. Other causes include thyroid problems and some medicines. Laser reduces the hair that is there, but it does not change what is producing it, so new hair can keep appearing.
If you also have irregular periods, acne, thinning scalp hair or sudden weight change, mention it. A doctor may suggest tests. Sudden, rapid hair growth or a deepening voice should be checked promptly. The laser hair reduction page explains how this fits into a treatment plan.
Is laser safe for Indian skin?
It can be, when the laser type and settings are chosen for your skin. Darker skin holds more pigment, so the laser has to be used with more care to reduce the risk of burns and pigmentation. This is why skin assessment and a test patch matter more than the machine's name.
How do I prepare?
- Do not wax, pluck or thread for several weeks beforehand. The laser needs the root in place. Shaving is usually allowed.
- Avoid tanning and strong sun. Recently tanned skin can mean a session has to be postponed.
- Tell the doctor about medicines, including isotretinoin, antibiotics, and anything applied to the skin.
- Mention pregnancy or breastfeeding. Laser hair reduction is usually postponed during pregnancy.
What does it feel like, and what happens afterwards?
Most women describe a warm snap, and the upper lip is often the most sensitive area. Mild redness and slight swelling around the hairs are common for a few hours. Rarely, burns, blisters or changes in skin colour can occur, so report anything unusual. Use sun protection on the area between sessions.
Questions to ask before you begin
- Who will perform the procedure, and what is their training?
- Is my hair and skin type suitable, or will the result be limited?
- Could a hormonal cause be involved, and do I need tests?
- How many sessions are realistic, and what will maintenance look like?
Good information before the first session matters more than speed. If laser is not suitable for your hair type, you should hear that before you start.
