OMG! I am 13 years old and I have the exact same problem with my baby hairs! Unfortunately I don't know how to fix it when styling hair but what I do is I take a shower before I go to bed but I don't wrap my hair in a towel I brush it out and leave it to air dry so the baby hairs don't stick up, because when I leave it in a towel the baby hairs come up. And for the frizz spray hair spray on your brush then just brush through your hair. It really works
