How to fix my fried hair?

okay I feel like an idiot! This is my very first time ever having fried hair and I admit I'm kind of freaked out! I have a hair appt. on Saturday. I have really short hair like Rihanna inspired. Like the short buzzed up back with the heavy front... everything is ok! But the front (long part) of my hair is effed up! Kinda scared to go to my appt. because I'm afraid of what she will say or even do.. My hugest fear is having to shave my head which I really hope it doesn't have to come to that? Once again this is the first time this has ever happened to me so I'm quite clueless. I've heard of mayonnaise helping it and olive oil. I don't have any olive oil but I have mayonnaise and I tried that lol didn't really work. Some one pleassse help me with some advice, answers, tips. all jokes aside please. thank you
