Clinical studies have evaluated PRP for androgenetic alopecia, with outcomes varying between individuals. Your doctor will discuss what may reasonably be expected based on your hair loss pattern and assessment.
The number and timing of PRP sessions depend on individual needs and the treatment protocol recommended by your doctor. Changes, where they occur, are generally assessed over several months using photographs and follow-up reviews.
PRP preparation and treatment protocols also vary between studies, which can affect how results are compared. Research is continuing to establish more consistent preparation methods and treatment schedules.
PRP does not address every underlying cause of hair loss, so maintenance or other treatments may be discussed depending on your diagnosis.
