Intradermal injection sessions incur minimal downtime; mild erythema and tenderness resolve within 24–48 hours. Patients resume normal scalp care and hair washing immediately. Systemic effects are negligible. Visible clinical changes (new hair emergence, reduced shedding) typically begin at 6–8 weeks and intensify through 6 months. No hair-cycle synchronisation adjustment is required.
Representative trials document hair density and thickness metrics using phototrichography and image analysis. Phase I–II cohorts report mean hair density increase of 15–35% over baseline in 50–65% of participants within 4–6 months of intradermal exosome injection or topical serum application. Terminal hair transition (vellus to terminal fibre diameter) occurs in 30–45%. Blinded assessor ratings and patient self-assessment show concordance in approximately 60–70% of cases. Durability studies extend to 12–18 months; some re-growth stabilises, whilst other patients require re-treatment.
