i am 19 from assam india.i used to keep my hair to medium length, then my girlfriens said that i am losing hair. so i decided to buzz it. since then i have a little insecurity when people look at my head. my hair was thin from birth and never noticed my hairline and was having a full head of hair. i am seriously worried because my scalp can be seen under direct light after buzzing. what can i do from now? worried. nobody is bald in the family. Sorry for the quality of the pics, picture was clicked from the webcam

Photos hard to tell, but probably diffuse thinning. Take propecia.
