Hi..Im a 21 year old boy...although i have had low level of hair fall for a few years..which could be a normal thing...i noticed suddenly in last 2 months that my hairline has receded from sides to an extent and hair thinning has visibly taken place over the top areas of the head up to an extent..although i don't see any proper bald spot as such but hair in the back areas has considerably thinned and scalp is visible to an extent over these areas.I don't know the sudden cause of this but mostly it could not be genetic as no one among my blood relatives has pattern baldness..not at least at young age..stress could be a factor and iv heard that anti dandruff shampoos could also cause this...my main concern is whether this would aggravate into baldness or not.Could you please give some advice and recommend some good hair dermatologist in Mumbai..thank you
