hair loss prevention

They say 90% of hair loss is hereditary; is there really no way to stop it?

My hair falls out like molting at a specific time of year, but when I ask people around me, they say it's because of the change of seasons.

I'm not sure if that's true, and I also wonder if the nutrients aren't being distributed evenly because my hair is long.

Your forehead was already wide, but it looks like it's going to become as wide as the Pacific Ocean.

I don't know where to start, whether I should take medicine or cut my hair short.
