AM I GOING BALD??! Help

so, recently i’ve noticed that my hair is getting thinner the june & july(summer). I was curious if I am losing a irregular amount of hair. So when I was taking a shower the strands that would fall out I would collect. I don’t know if my age has to do anything with it but I’m 12 & I was wondering if you can help me see if my hair fall out was too much (btw throughout the school year I would straighten or put heat on my hair & shower every day) < I’m wondering if that also has something to do with it, but pls help me out I’m scared I might go bald.. and if I am going bald pls tell me some ways to stop losing an excessive amount of hair
