So I very recently turned 20 and have noticed some male pattern baldness. With the right haircut I can cover the pattern, but of course it's still there. I have noticed my hair on the top thinning, though I haven't really noticed hair falling or hair on my pillow. I also sometimes have dandruff and some seborrheic dermatitis, but with regular shampooing I'm able to control these things. After using a certain type of shampoo my barber said that my scalp wasn't red and looked fine.
Anyways, I should also say that there's a family history. My mother's father side of the family has a history of hair loss, I have several relatives that began losing their hair in their 20s, one relative at my age. Many of these relatives are semi-bald in their late 20s. In my ethnicity in general, it seems many people experience hair loss from early age.
I'm not overly obsessed with my hair (I prefer my hair short anyways), and wouldn't want to do any surgeries, but if possible I'd like to slow down any such hair loss in a normal way. I've been taking some vitamins for hair as I'm not a fan of applying 100 chemicals to my scalp. Any advice would be great. A couple photos are attached.
the lighting/photo quality is not great, but as you may see the thinning at the top. Thanks in advance
