Just how long is your hair, and is it thick?

The reason I ask is because my hair is passed my shoulders and very thick, and I shed like chow in the summertime. Anyway, I found out from the lady where I get my hair trimmed at, is that particular type of hair is prone to 'shedding' because of its weight.

Which is why I'm >< close to whacking it all off like I normally do. God only knows why decided to let it grow out several months ago.
