Why can't it be done in one session?
At any given moment, only a portion of your hair is in the active growth (anagen) phase — the phase where laser is effective. The rest is dormant and won't respond yet. Each session treats the hairs that happen to be active, so you need several sessions, timed to catch different hairs as they cycle into the active phase. This is biology, not upselling.
How many sessions on average?
As a general guide, a course of several sessions is typical, with results building gradually across them. Body areas and facial areas can differ, and denser or hormone-influenced hair (and some facial areas) may need more. Your clinician gives you a realistic estimate after assessing your hair and skin — and you'll usually see noticeable reduction partway through the course rather than only at the end.
How far apart are sessions?
Sessions are spaced several weeks apart to align with the hairgrowth cycle — body areas are often spaced a little wider than facial areas. Spacing them correctly matters: too close together and you're treating dormant follicles that won't respond. Sticking to your schedule is one of the biggest factors in getting good results efficiently.
What affects how many you'll need?
- Area— coarse, dense areas vs fine, sparse ones
- Hair colour and thickness— laser responds best to darker, coarser hair
- Skin tone— influences device and settings, and sometimes pacing
- Hormones— hormonal factors (e.g. PCOS) can increase regrowth and the need for maintenance
- Consistency— missing sessions delays results Your plan is personalised to these factors.
Will I need maintenance afterwards?
Often, yes — occasional maintenance sessions help keep results, since some fine regrowth can occur over time, particularly where hormones play a role. This is normal and part of why laser is best understood as long-term reduction you maintain, rather than a permanent one-and-done.
