Can I repeat PRP in 15 days?

I recommend treatments 4-6 weeks apart, however it is really up to your provider. I don't think it would cause any harm if you had another treatment, but I would consult with your provider.

PRP treatment is applied at 4-6 week intervals and are made for 4-6 sessions in total. Of course it changes for patients situation. Doctor,s advice is really important in this.

Unfortunately,at present there is no standardized clinical protocol as to the time interval between PRP sessions.Most experienced Hair surgeons feel that it should be done every month to 3 months for the first year of treatment.There is no harm in doing another treatment in 15 days,it's just unclear whether or not you will benefit.
