- Week 0–2
- VEGF upregulation begins; actin binding in dermal papilla cells
- None. May notice increased shedding
- Baseline photo documentation recommended
- Early shedding indicates follicle phase transition. Continue protocol
- Week 4–6
- Angiogenesis around follicles; capillary density increases 30–50%
- Reduced daily shedding; improved scalp condition (less flaking, redness)
- Manual hair counts; scalp texture assessment
- First positive signal. Vascular changes precede growth
- Week 8–10
- Miniaturised follicles enter anagen phase; keratinocyte proliferation increases
- Fine regrowth visible in thinning areas (vellus hair)
- Trichoscopy shows increased follicle density
- Vellus hairs will thicken over subsequent cycles
- Week 12–16
- Shaft diameter increases; anagen duration extends
- Noticeable density improvement in previously sparse areas
- Phototrichogram; standardised hair part width measurement
- Peak velocity of visible change. Most users report satisfaction at this point
- Week 20–24
- Follicles reach maximum diameter potential for current protocol
- Terminal hair replaces vellus hair; overall coverage improvement
- Professional before/after photography; dermatoscope comparison
- Maintenance dosing begins. Further improvement requires protocol adjustment
