Treatment Frequency Design: Matching Effect Cycles to Business Rhythm
Three Constraints on Frequency
- Physiological cycles: ~28-day epidermal turnover, multi-week follicle cycles, month-scale collagen remodeling — cadence must respect repair rhythms.
- Cumulative logic: most programs accumulate (each pass clears part of the target); intervals should let the next target cohort arrive.
- Business rhythm: frequency sets visit rates and card cycles — translate sensible physiology into card structure (see program cards).
Reference Table
| Program | Frequency | Basis |
|---|---|---|
| IPL | Every 3-4 weeks | Pigment and vascular cycles |
| Laser hair removal | 4-8 weeks by area | Anagen ratio |
| RF microneedling | 4-6 weeks | Dermal repair cycle |
| Non-ablative fractional | 3-4 weeks | Gentle cumulative rebuild |
| Body circulation | Weekly | Edema and feel maintenance |
| Scalp care | Weekly × cycle | Environment improvement |
| LED repair | 2-3× weekly | Photobiomodulation dose window |
Two Design Principles
- Sparser beats denser (for trauma work): stacked injury raises sensitivity and PIH — “more is more” fails in energy-based care.
- Sustainability first: the frequency a client can keep is the effective one; ask about commute, budget and routine at design time.
FAQ
Client wants tighter spacing?
For trauma-based work, hold the physiological floor, reschedule and explain — frequency discipline protects results and safety.
Does a long gap void progress?
Depends on the program and the gap: one missed cycle usually just continues; months off re-enters at half course. The archive record is the referee.
