AH! Can you help me with my frustrating hair?

Try use an anti-frizz shampoo and conditioner, and a frizz controlling serum. When you straighten it, make sure to use a heat protectant spray as well; this protects your hair from being damaged by the straightener, and helps prevent some frizz. Also check what kind of hair straightener it is and how hot it is; if it some $20 cheapy, it will probably not help or even worsen the frizz, while more expensive models >$100 will usually have ionic properties to defuse some frizz. And make sure that the straightener isn't too cold or warm, and that it is 100% dry when you straighten. Hope this helps! :)
