Hair shedding after hair transplant explained: why shock loss occurs, when it happens and what to do — and what to avoid.
The biology of post-transplant shedding
Post-transplant shedding (shock loss) occurs because surgical trauma forces transplanted follicles into telogen — the resting phase of the hair growth cycle. In telogen, the follicle stops producing new shaft growth and the existing shaft is shed. This is the same mechanism as stress-related telogen effluvium that many people experience after illness, surgery or significant stress. The difference with post-transplant shock loss: it is predictable, universal and temporary.
The shedding is of the hair shaft only — the follicle remains alive and intact beneath the surface. After the telogen phase, the follicle re-enters anagen and produces permanent new growth.
Two types of shedding — what each means
Transplanted hair shedding: Universal — essentially all transplanted hairs shed within 2–6 weeks of surgery. Expected, normal, and not a cause for concern. Growth resumes from the same follicle at months 3–5.
Native hair shedding: Occurs in some patients — native hairs near the recipient zone shed temporarily due to disrupted blood supply and the inflammatory response. Resolves within 3–6 months with complete recovery. More likely when native hair is already miniaturised by DHT. More common than most patients expect; rarely as alarming as it initially appears.
What to do during shedding — and what to avoid
Do: Follow the washing and aftercare protocol. Take monthly photographs. Continue Finasteride if prescribed. Contact the clinic if genuinely concerned.
Don't: Stop Finasteride — shedding phase is when native hair is most vulnerable. Scratch or aggressively massage the scalp. Interpret universal, expected shedding as surgical failure. Assess progress before month 5–6.
