Female pattern loss is diffuse, and roughly a third of cases have a medical cause that surgery would not fix.
Thyroid disease, iron deficiency, PCOS and postpartum change all cause diffuse shedding that looks like pattern loss. Transplanting into an untreated medical cause wastes grafts and money. We ask for ferritin, thyroid panel and vitamin D before planning.
It works well for a receded frontal line, widened part, temple loss and scarring alopecia that is stable. It works poorly for diffuse thinning across the whole scalp, because the donor area is often thinning too.
Most women can be treated with only a small donor strip trimmed, hidden beneath the surrounding hair. The technique is slower and therefore capped at fewer grafts per session, but it means returning to work without explanation.
The goal is usually to restore a frame — hairline, part line, temples — rather than uniform density. Combined with PRP and medical management of native hair, that produces the most satisfying outcomes.
In most cases no — only a small donor area is trimmed and stays hidden under your own hair.
