Does hair transplantation work, and when are results visible?
Hair transplantation can improve coverage in selected areas when suitable donor hair is available, but outcomes vary and no success rate guarantees an individual result. Growth takes months, and non-transplanted hair may continue thinning.

Who may be suitable?
The clinician assesses the cause of hair loss, donor density, scalp health and expectations. Some forms of hair loss are unsuitable for surgery. Transplantation relocates existing follicles rather than creating an unlimited supply. Treating an underlying condition or stabilising hair loss may come first.
How results develop
Transplanted hairs may initially shed before new growth appears. NHS guidance describes a possible ten- to eighteen-month interval before the full result is visible. This is a general range, not a deadline or guarantee for every patient.
The technique name is not enough
Discuss hairline design, scarring, aftercare, infection and poor graft growth. A label such as follicular unit extraction cannot establish the quality of an individual result. Ask how the plan accounts for ongoing loss of original hair. Severe pain or unexpected postoperative symptoms should be reported promptly to the surgeon.
