Hi Karen - I know how your feeling and it is very difficult. I am 26 and losing a lot of my hair on top and front portions of my scalp. It really helps to get educated and read up on the posts....educate yourself and start a treatment regimen. Also, go see a doctor and have hormaonal blood tests done - maybe theres a medical issue that can explain your hair loss.
I have to be honest - doctors tend to not be very educated once it comes to female hairloss - but don't give up if they don't know the answers - keep looking and reading up on it yourself......read this site inside out........
