Hi, Amen,
Start your research here. Tons and tons of info. And women and a few men who are compassionate, funny, friendly, of all ages and walks of life, who want their hair to look its best. Give it a whirl. You'll learn a lot, and maybe find help in taking the next step.

And, depending on how much hair thinning you are dealing with, you may not need to wear a wig. Last spring I finally decided to do something, and I found out a hairpiece that gives me hair on top and at the hairline is all I need. I'm pretty happy with what I found out.
