Hello. Thank you for writing to us
Platelet rich plasma therapy Or PRP is a recent advancement in the treatment of hair loss and alopecia.
The principle behind using it is that human platelet are a rich source of growth factors and these platelet derived growth factors have a stimulatory effect on hair follicles and help in arresting hair fall
as well as regrow new hair.
This therapy utilizes patients own blood which is double centrifuged to separate and then further concentrate platelet fraction.
This platelet fraction is then injected into the affected area where platelet derived growth factors are released directly into the tissue.
This treatment has been mainly tried in androgenetic alopecia but recently even in alopecia areata
as well; its use has been reported in the literature with good results.
A session of PRP is recommended once every 2-3 months for a total of 3-4 sessions.
Results are long lasting and durable but they need to be maintained either with maintenance sessions of PRP or combining it with with other treatment modalities.
It can be combined with other treatment modalities like minoxidil
The cost of treatment varies from doctor to doctor and you must ask your local doctors for the same.
