Male Baldness Info

under light i kinda looks like i have male pattern baldness. but in a regular mirror with not that strong of a light it looks thicker !????!

I guss i had aot of hair fallout through the recent year do to alot of gel usage. I dont know if its male baldness or anything. Nobody in my family has ever experienced that, but i have alot of hair, just not as much as i used too. Its gotten alot thinner. I have cut my hair and haven’t used any chemicals in it for a while, hoping it would start to comeback. What can i do, to get it to grow thicker?
