thinning of male hair is very common and can be normal in men as we get older.
but you should see your doctor and get some blood testing.
low thyroid hormone levels, low iron, low b12, low biotin can all cause thinning of hair.
use of a marijuana can cause blood vessels to constrict and can increase your blood pressure
marijuana can also decrease your testosterone levels
lower testosterone levels can affect semen volume as well
you should see your doctor to get some blood testing
and seeing if you stop marijuana use, if your hair and semen get better
