Hi Tina,
If your hair is really thin, you need a layered cut with a fringe or bangs. This will add width and volume to your forehead.
Other haircuts for thin hair and a receding hairline are bob, pixie, shag, buzz cut, and short sides with longer back and top.
The ideal is the bob cut. A bob cut is classic and looks good on anyone. A bob cut also has a longer length, so it helps to add more volume to your hair. Also, if you would like your hair to have a more curly look, a curly bob cut can also help add volume to your thinning hair.
