Male Baldness Info

When I comb my hair infront I usually pull a few hairs out (some have little white dots on the end). It’s not especially thin, but it is thinner than the rest of my head.
My dad is bald, and so was his father and all of his brothers.
My mother has all her hair, and so does everyone on her side of the family.
I also dye my hair occasionally (around 5 times since last summer), and bleach certain parts (I’ve done this twice, once on the side, and once infront). I also straighten my hair every morning.
I know these things can make your hair thinner, but straightening my hair usually doesnt make my hair thinner until after I do it.
My hairline seems fine, it comes down normal infront and doesn’t doesn’t go back on the sides as far as most guys my age (16).
Could my thin hair in the front of my head be caused by something other than male pattern baldness? When I search that’s all that comes up.
