Losing more and more hair each day. Help!

[nb1992]

I've been losing my hair for the past 8 years. I noticed it about 5 months after I had my 3rd child. I've tried minoxidil, but never kept it up for long enough to notice a change. Two of my sisters and two brothers are also going through this; although, my parents have a full head of hair. I've attached pictures to see if anyone can suggest treatments or am I too late. I do have a dermatologist appointment in two weeks. My hair loss is really starting to affect my selfesteem. I hope I'm not too late to do something, anything about my hair loss.
