Is my DHT level causing mild hair fall and flaky scalp?

Hi doctor,

I am 19 years old. For the past three months, I have had mild hair fall. I lose around 2 to 10 hair after every shower. I have never had hair fall in the past. I also did a background check with my family history; none had any baldness even in the 70s. I fear this would be the result of masturbation habit, which could have boosted DHT. So far I have lost about five percent of my hair. Though there are no visible bald spots, I can say my density has reduced a lot. I also have a flaky scalp, 0.4" to 0.8" sized flakes and that would cause snowfall like scenario. When I touch my hair, my scalp is shedding like a tree in fall. Would that be the reason for my hair fall or the DHT?

I have been using Noskurf lotion and Aminexil shampoo from the past 15 days, which reduced the flaking a bit. It is like my head is flakes-free for a couple of days and again it reappears. But it did nothing to stop my hair fall. I saw that most of the hair that fall are either too thin and smudged irregularly or are tiny new hair. I also feel pain and heat over the scalp which is succeeded by the localized hair loss after a couple of days. Since I joined MBBS course, I am not on a proper diet. Could this hair loss be due to biotin?
