Laser Hair Removal · Sessions · Pacific Plaza
How many laser hair removal sessions you need depends on how many follicles are growing in each area at each visit, which differs between the face, underarm and legs, and on how much energy your skin allows. At Atelier, Dr Sin Yong gives a starting estimate, then times each next visit from what has regrown.
No number fits everyone. Atelier's laser hair removal page gives a common course of 6–8 sessions at 4–6 week intervals, but that is a starting estimate, not a promise. Each area runs on its own hair cycle, and the next visit is decided from what has grown back. A count fixed before your hair is seen is a sales figure, not a plan.
The Hair Cycle
Each follicle moves through a growth phase, a short regression and a resting phase. The pigmented bulb sits next to the cells that make hair only while the hair is growing, so only then can the laser's heat disable it. A pulse over a resting follicle warms the shaft and achieves nothing.
So every visit treats the group that happens to be growing that day, and the others are reached as they enter growth. The aim is a long-term, stable reduction in regrowing hair, not the loss of every hair, and what returns is usually finer and lighter, which changes the settings for later visits.
Spacing
The share of follicles growing at once, and how long the rest stay resting, differ across the body. Visits are timed to that, so areas started together are not always due together; the face may be ready sooner and the legs later.
| Area | Hair cycle | Effect on visits |
|---|---|---|
| Upper lip and chin | Short; many follicles growing at once | Visits can sit closer; on the chin, hormones keep adding follicles |
| Underarm | Short to moderate; dense, coarse hair | Early visits catch a large group; later ones target finer hair |
| Bikini line | Moderate; coarse, curved hair on often darker skin | Timed by regrowth, with cautious settings |
| Legs and arms | Long resting phase; few follicles growing at once | Spaced further apart; too soon reaches the same hairs twice |
| Beard, chest and back | Moderate; very dense hair, driven by androgens | Worked zone by zone; maintenance discussed honestly |
Pace
Contrast. Dark hair on light skin tolerates the most energy per visit. As skin pigment rises, energy must come down, so fewer follicles are disabled each time; darker skin usually means the 1064 nm wavelength and a gentler pace. A tan between visits has the same effect.
Hair. Dense, coarse, dark hair responds readily but sheds in stages. Fine or light hair responds unpredictably, and grey or white hair not at all, whatever the number of visits.
Hormones and history. Androgen-driven areas can keep recruiting follicles after a course. Earlier IPL or laser elsewhere often leaves finer, lighter hair, and years of waxing or plucking can distort follicles.
What helps: shaving rather than waxing between visits, sunscreen, and telling the clinic about new medicines or earlier treatment.
At Atelier
Each visit starts with a look at the treated areas: how much hair has returned and how coarse it is, how the skin responded last time, whether settings or wavelength should change, and whether to pause. Areas are judged separately, and the underarm is often well ahead of the legs. Shave a day or two before rather than that morning, so the regrowth can be read. New or quickly increasing hair in women is assessed for a hormonal cause, as on facial laser hair removal. How a written quote for a course is put together is on how we quote.
