Ok heres the story since i was 14 i've noticed my hair was thin.. I remember getting comments about how thin it was as far back as my 8th grade year in middle school. I've been to acouple doctors and currently on propecia for about a year now my hair stays the same no gain or loss. For the longest time i tried to figure out what it was but from reading all these forums i believe it was from a diet i was on. Back to the summer before i was going into 8th i lost 38 pounds in 2 months. Which is around the time i noticed my hair being thin. Its weird NOT a single person in my whole family has hair loss not my dad, brother, uncles, grandfathers Nobody they all have they're hair. Looking at pictures before the unfortunate event i had really thick hair. Think a hair transplant would help thickin it up i'm 20 now? Btw i don't have a receding hair line either my hair line is really low.
