Laser hair reduction is one of the most popular treatments at Skin First — and one of the most misunderstood. Patients often come in having been told they need exactly "6 sessions" by another clinic, only to find results vary widely. Here's the truth from a dermatologist's perspective.
How Laser Hair Reduction Works
Laser hair reduction works by targeting the melanin (pigment) in the hair follicle with concentrated light energy. This heat destroys the follicle's ability to regrow hair — but only when the follicle is in its active growth phase (called the anagen phase). Since not all follicles are in this phase simultaneously, multiple sessions are needed to catch each one at the right time.
So How Many Sessions Do You Really Need?
The honest answer is: it depends. Here are the key factors:
1. Body Area
- Upper lip / chin — 8-12 sessions (hormonal influence means regrowth is more stubborn)
- Underarms — 6–10 sessions (faster results, coarser hair responds well)
- Full legs / back — 8–10 sessions (larger area, varied hair density)
- Arms — 8–10 sessions
2. Your Skin Tone and Hair Colour
Laser works best when there is high contrast between skin tone and hair colour — i.e. dark hair on lighter skin. For patients with darker skin tones (common in Surat), we use specific laser wavelengths like Nd:YAG that are safe and effective without risking burns. Blonde, grey or white hair does not respond to laser — it lacks melanin.
3. Hormonal Factors
Conditions like PCOS (polycystic ovary syndrome) cause hormonal hair growth that is harder to treat. These patients often need more sessions and periodic maintenance. Dr. Jeet Gandhi always screens for hormonal causes before starting treatment.
4. Consistency of Sessions
Sessions must be spaced 4–6 weeks apart for the face and 4–8 weeks for the body. Skipping or delaying sessions allows missed follicles to re-enter growth phases, reducing overall effectiveness.
What to Expect at Skin First
- A detailed consultation and skin assessment before any treatment begins
- A patch test to confirm your skin's response to the laser
- Treatments performed by trained staff under dermatologist supervision
- Use of cooling technology to ensure comfort during the procedure
- Typically 10–60 minutes per session depending on the area
Aftercare Tips
- Avoid sun exposure for 48 hours before and after each session
- Apply SPF 50 sunscreen daily throughout your treatment course
- Do not wax or thread between sessions — shaving is fine
- Mild redness for a few hours after treatment is normal
The Bottom Line
Most patients in Surat achieve 70–90% permanent hair reduction after a full course of sessions. The exact number depends on your individual profile. At Skin First, we give you an honest, personalised estimate at your first consultation — not a one-size-fits-all number.
