i'm just curious about something? has anyone on this site had their hair grow back and stay in? everytime i tell someone else about what's going on with my daughter, they happen to know of someone who lost all their hair but now has it all back again. every day i hear this from someone. today, i heard it from one of my mom's friends, but she said the man became impotent from the pills he took for his hair regrowth. i'm still in my hopeful stage since it's only been about 3 weeks since my daugher started losing her hair (for the 2nd time). most of the dr's we've seen aren't feeling too good about what's going on. she's never had her blood tested for anything. does this need to be done? we are going to an alopecia specialist in a few weeks.
