I have been losing a lot of hair and the cause of this can be a lot ,either it is because i havve the habit of pulling my hair at all time or may be the kind of shampoos that i use could be the reason.earlier i had a little bald patch but then now i am partially bald ,it scares me that what will happen if i lose all my hair at this rate.my friend asked me that i should buy a wig to hide the baldness,and nobody would come to know about it at all.but then i want a blackish brown wig that is of a good quality as well as cheap on my pocket?
