Tired of the endless cycle of shaving, waxing, and dealing with ingrown hairs? Laser hair removal offers a permanent solution. Here's your comprehensive guide to understanding the treatment, managing expectations, and getting the best results.
How Laser Hair Removal Works
The laser emits a concentrated beam of light that's absorbed by melanin (pigment) in the hair follicle. This light energy converts to heat, which damages the follicle's ability to produce hair. The surrounding skin remains unaffected because the laser selectively targets the darker pigment in the hair.
Why Multiple Sessions Are Needed
Hair grows in three phases: anagen (growth), catagen (transition), and telogen (rest). The laser only affects hairs in the active growth phase — when the hair is connected to the follicle and contains the most melanin. Since only 20–30% of hairs are in anagen at any given time, multiple sessions are needed to catch all hairs in their growth phase.
What to Expect: Session by Session
Session 1–2: You'll notice slower regrowth and finer hair. About 15–20% reduction. **Session 3–4:** Significant reduction becomes obvious. Patches of smooth skin appear. **Session 5–6:** 70–80% permanent reduction achieved. Remaining hairs are fine and sparse. **Session 7–8:** Up to 90% permanent reduction for most patients.
Treatment Areas
We treat all body areas — face (upper lip, chin, sideburns), underarms, bikini/Brazilian, legs, arms, back, chest, and abdomen. Each area has different hair density and growth cycles, so session counts may vary.
Pre-Treatment Guidelines
Avoid sun exposure and tanning for 2 weeks before treatment. Shave the treatment area 24 hours before (no waxing or plucking). Avoid retinoids and AHAs for 1 week before. Come with clean, product-free skin.
Indian Skin Considerations
At Delight Clinic, we use Nd:YAG and Diode lasers specifically suited for Indian skin tones (Fitzpatrick IV–VI). These wavelengths bypass melanin in the skin while effectively targeting the hair follicle, making treatment safe and effective for darker skin types.
Post-Treatment Care
Apply aloe vera or prescribed soothing cream. Avoid sun exposure for 48 hours. No hot showers or gym for 24 hours. Exfoliate gently after 1 week to help shed treated hairs.
Key Takeaways
- 6–8 sessions typically needed for 80–90% permanent reduction
- The laser only works on actively growing hairs — hence multiple sessions
- Indian skin types need specialized lasers (Nd:YAG/Diode) for safety
- Results are cumulative — each session brings you closer to permanent smoothness
