How long does PRP for hair loss take to work for male pattern hair loss?

Androgenetic alopecia affects the growth pattern and thickness of scalp hairs. PRP uses a preparation of your own blood components placed into selected scalp areas. Hair follicles still follow their growth cycle, so a treatment cannot make a new strand appear overnight. Reduced shedding, fine regrowth or improved fullness may be noticed at different times, and photographs under similar conditions are more useful than daily inspection.

Attend the treatment schedule recommended for you and keep review appointments so the scalp can be assessed consistently. Take comparison photographs with the same lighting and hair position. Tell your clinician about ongoing shedding, scalp disease, medicines and any recent illness. Avoid judging the outcome immediately after treatment, when injection-site tenderness or temporary swelling can distract from longer-term changes.

Contact the clinic promptly for worsening pain, spreading redness, marked swelling, drainage or fever after injections. Arrange review if shedding is sudden or patchy, the scalp becomes inflamed, or there is no meaningful change by the reassessment point. These findings may call for a diagnosis check or another treatment plan.

Ask what outcome will be measured, when your first comparison review should occur, and whether another cause of shedding needs checking. Ask how PRP fits with other treatments and what maintenance plan is expected.
