Is there something wrong?

Hey guys so I have been losing hair like crazy and I mean lots and lots of hair, I’ve been taking iron pills and hair skin and nail pills for about a month now. And I haven’t seen a difference, in fact I feel like it’s gotten worse. I’m 21 years old and I stopped having crazy breakouts when I turned 18 but rn my forehead is covered in cystic acne and blackheads. I’m also not on my period. Should I be worried this could be something more serious?
