How Many Sessions for Laser Hair Removal?
Understanding the Numbers
If you’re asking how many sessions for laser hair removal, you’re already ahead of the curve. The short answer is: it depends on your body area, hormones, hair colour, and commitment to a treatment calendar. The long answer—backed by Vectus® clinical data and our years of experience—follows below.
Hair-Growth Biology 101
| Phase | What’s Happening | Laser Impact |
| Anagen (Growth) | Hair shaft attached to follicle; rich in melanin | Laser energy travels down shaft and disables the bulb |
| Catagen (Transition) | Follicle detaches, pigment decreases | Partial response; less efficient |
| Telogen (Rest) | Hair dormant, ready to shed | No effect |
Because only 10–20 % of hairs are in anagen at any moment, multiple visits spaced weeks apart are the only route to near-total clearance.
Vectus® Session Guidelines
| Body Zone | Typical Sessions | Interval | Why the Range Varies |
| Upper Lip / Chin | 8–10 | Every 4 weeks | Hormonal and fine hair; PCOS may add boosters |
| Underarms | 8–10 | Every 4–6 weeks | Dense follicles, hormonal influence |
| Bikini / Brazilian | 8–10 | Every 4–6 weeks | Coarse, pigment-rich hair clears faster but hormones can stimulate new growth |
| Arms / Legs | 6–8 | Every 6–8 weeks | Larger follicles, slower growth cycle |
| Back / Chest | 6–8 | Every 6–8 weeks | High density yet stable hormone influence (in most) |
Pro tip: Arrive within seven days of visible regrowth to keep your follicles in the target zone and shorten the overall timeline.
Factors That May Extend the Series
- Endocrine Changes – Pregnancy, menopause, testosterone therapy
- Photosensitizing Medications – Certain antibiotics, isotretinoin (Accutane)
- Recent Tanning – Forces lower fluence settings, reducing efficiency
- Hair Colour – Blonde, red, or grey lack melanin; may need extra passes or electrolysis
Keeping You Comfortable Through Every Visit
- Pre-session: Shave 24–48 hours prior, skip lotions and deodorant.
- During: Numbing cream + Vectus® Contact Cooling™ dull the “snap.” Most guests relax on their phone or podcast.
- Post-session: Apply aloe, avoid heat and friction for 24 hours, and protect with SPF.
Long-Term Maintenance
After your primary series, expect 80–90 % permanent reduction. Annual “polish” sessions catch stray follicles that cycle back into anagen over time, especially in hormone-driven areas.
