Triphasic Guide: Reactional vs Progressive in San Francisco Shedding can follow stress, illness, postpartum, or seasonal shifts (Reactional) or creep in over time as finer strands and a widening part (Progressive).
Reactional protocol (8–12 weeks): • Ampoules 2–3×/week on clean scalp; massage 2–3 min. • Triphasic shampoo 2–3×/week; avoid hot water. • Keep lengths light (Tonucia/volume). • Sleep on silk; lower heat on mask days.
Progressive protocol (3 months+): • Vials per box schedule; apply on dry/towel-dried scalp. • Triphasic shampoo 2–4×/week to keep follicles clear. • Protect lengths; avoid tight styles; add UV hat for weekend sun.
Milestones: fewer shed hairs in shower by week 4–6 (Reactional); root fullness and scalp comfort by 8–12 weeks (Progressive).
