I am a 19 y.o male with M shape receding hairline. I have been diagnosed with MPB and I had a few questions. If I continue PRP and Minoxidil then, 1) will it be able to regrow the thinning hair at my hairline? 2) How long will PRP and Min only prevent further hair loss given that I use them continuously? 3) After 25, can I get a hair transplant with Min and PRP as my preventative regimens only? 4) Since my hairline has already receded to M shape, am I destined for advanced balding pattern?
