Hair fall related. Sleep for 6-7hours.

I have been facing hairfall issue from past 3-4years but in last 1year the problem has increased. The whole upper part is affected, I have lesser hairs compared to few years ago, and in the front left-right side the baldness is now visible whereas in the middle of head it seems that in next 6-12months it will be visible. This problem isn't hereditary (mother's side/father). I have a thin and slightly brown hairs right from childhood. My skin is very oily and also my body is warmer compared to others, maybe that's why It sweats alot. Previously I had pimples and the medicine for the same was done between 2014-2018 and it was stopped after that . Currently I am not taking any skincare related medicine. I'm currently taking becadexamin from past 2months. Also used indulekha oil for 3months but couldn't see any difference. I don't have any stress and normally sleep for 6-7hours.
