Hairs that Fall Out Are Different Thicknesses

I notice that when I brush my hair, some of the hairs that come out are thin and wispy and approx 6 months old, some are normal thickness but only about 3 months old. The rest of my fallen hairs are full length and obviously time for them to fall. Does this mean anything. Thanks

You can lose up to 100 hairs or so a day. They may break off when you are brushing and that could be the cause of the different lengths of hair. If you think your hair is thinning or falling out at an alarming rate, you should have you scalp hair mapped for miniaturization.
