Hairfall from hair, eyebrows and

Hey I'm 20 years old and I have been facing hairfall since last one year but last year I shaved my head and my hairfall stopped and after that last year in November I met with a small accident and my hair again started falling but this time it was more than ever maybe like 50 to 100 hair a day and last week I shaved my hair again but now i have started to loose my hair from eye brows and from my sideburns as well whenever I try to pluck hair from that part...I have consulted 3 doctors from Practo but I can't find a permanent solution to my hairfall every doctor at the end recommends me minoxidil..please help me cause I'm very young just 20 years old and I don't think that I'm facing androgenic hair loss and I have been working out and physically active from last 1 year
