"Many patients come to us who have spent years on waxing every month. After a proper course of laser hair removal — typically 6 to 8 sessions — they achieve 80 to 90 percent permanent reduction and wish they had done it sooner," says Dr. B. Jyothi, Consultant Dermatologist and Cosmetologist, Lalitha Chest & Skin Hospital, Karimnagar.
How Does Laser Hair Removal Work?
The diode laser emits a wavelength of light (800–810 nm) that is specifically absorbed by melanin (the pigment) in the hair shaft and follicle. The light energy converts to heat, which destroys the hair follicle — permanently preventing that follicle from growing hair. The surrounding skin is protected by the laser's built-in cooling system.
Multiple sessions are needed because the laser only destroys hair that is in the active growth phase (anagen) at the time of treatment. Hair cycles through three phases (anagen, catagen, telogen) and only 20 to 30 percent of follicles are in the active phase at any one time.
Treatment Areas
- Face — upper lip, chin, sideburns, jawline
- Underarms
- Arms (full or half)
- Legs (full or lower)
- Bikini and intimate areas
- Back and chest (common in men)
- Abdomen
How Many Sessions Are Needed?
Most patients achieve excellent results in 6 to 8 sessions, spaced 4 to 6 weeks apart. The face and upper lip often need 8 to 10 sessions due to hormonal hair. After the course, most patients need 1 to 2 maintenance sessions per year — significantly less effort and cost than regular waxing or threading.
What to Expect — The Session
- The area is shaved 24 hours before the session (do not wax or thread beforehand).
- A cooling gel is applied and the laser handpiece is moved across the skin. Modern diode lasers have in-built cooling that makes the procedure comfortable — most patients describe it as a warm rubber-band snap.
- Session duration: 15 minutes for the upper lip; 45 to 60 minutes for full legs.
- Mild redness for 1 to 2 hours afterward is normal. No downtime required.
Who Is a Good Candidate?
Laser hair removal works best when there is contrast between hair colour (dark) and skin colour (lighter). Modern diode lasers with 808 nm wavelength are safe and effective for all Indian skin types (Fitzpatrick III–V). It is less effective on white, grey, or very light blonde hair. Candidates must not be pregnant or breastfeeding, and active skin infections or tanned skin in the treatment area must be avoided.
Preparation and Aftercare
- Before: Avoid sun exposure for 2 weeks. Shave (do not wax) 24 hours before. Arrive without lotions or makeup.
- After: Apply soothing aloe vera gel. Avoid direct sun for 1 week. Use SPF 30+ daily on treated areas. Avoid heat (hot baths, saunas) for 24 hours.
Frequently Asked Questions
Q: Is laser hair removal permanent?
Laser hair removal provides significant permanent reduction — typically 80 to 90 percent after a full course. It is not 100 percent permanent for all follicles, and hormonal changes can stimulate new hair growth over time. Annual maintenance sessions maintain results.
Q: Is it safe for Indian skin tone?
Yes — modern diode lasers at 808 nm are specifically effective and safe for darker Indian skin. We assess your skin type in the initial consultation and set parameters accordingly.
Q: Will hair grow back thicker or darker after laser?
No. This is a common myth. Laser hair removal reduces hair growth with each session. Any hair that regrows comes back finer and lighter than before.
Q: I have PCOS with facial hair. Can laser help?
Yes, but more sessions may be needed, and maintenance sessions may be required more frequently, because PCOS creates ongoing hormonal stimulation of hair follicles. Combined management with your gynaecologist for PCOS itself gives the best long-term results.
