I first started to notice my hair loss on my temples 6 months ago.I did not expect to lose any hair in my life,but especially so young because my father or his brothers never lost any hair,my grandfather on my mothers side never lost any,the worst case of male pattern baldness in my family was my grandfather on my fathers side-who still had a substantial head of hair when he died ,people tried to reassure me by attributing it to stress as i am doing an important exam-i have been feeling stressed, but it is hard to remain optimistic when it is still falling out at a frightening rate. Could this be stress related? I went to my doctor twice about this.The first day he told me that male pattern baldness is inherited so i am unlikely to lose my hair and it could be stress related and even if i do there are products on the market to help it. The second day he told me that it is not inherited and occurs in males randomly also basically said it was male pattern baldness,he said the products on the market are ineffective.He must have forgotten that he spoke to me about it before its the only way to explain such inconsistancy. Which version should believe?What should be my next step if this keeps gettting worse? Is there a way to know for sure if its male pattern baldness?
