I've always wondered...

I am not sure if I can answer your question. I had thick hair as a kid. When I had children... a lot of my hair had thinned out conciderabley. It happens in your twenties. But I do know your hair is all different lengths. If you are in your twenties yet you can rub against your scalp and feel the stubs. If you notice at your hairline new hair pieces growing excpecailly at the corners of your forhead. Hope I was some help to your wonders.
