Concise answer
Shedding of implanted hair shafts can occur during early recovery while follicles remain under the skin. The timing and accompanying scalp signs determine whether review is needed.
The transplanted hair shaft and the follicle are not the same thing. A shaft can shed before a new growth cycle begins.
Increasing redness, pus, fever, worsening pain or unusual patchy donor change should not be dismissed as routine shedding.
When evaluation may help
Contact the operating clinic whenever recovery differs from the written aftercare plan or you are worried about the donor or recipient area.
