Hi . greetings. Prp is a recent advance in treatment of hair loss. Stimulates hair growth, better hair texture and thickening of hair. Also controls hair loss. Cost will vary depending on type of tubes used for prp preparation and place where you get it done. Usually around six sittings initially. Don't compromise and get it done by a qualified dermatologist who is aware of proper prp technique. Hope this helps. Warm regards. Dr Govind S Mittal, excel care hospital, Bangalore.
