It looks like you wear your hair tied back a fair bit, judging by the hair breakage... I wouldn't think it was thinning, though...
If you feel that it actually is thinning, try massaging your scalp... this will invigorate and revitalise the hair follicles and roots, stimulating the blood flow and encourage healthier hair growth... (I sound like a tele-commercial)1

but if that fuzz wasn't there before, like someone said, could be the start of traction alopecia0
