so my friend's mum is a hairdresser,and i went to ask her about it onmonday and she told me to come back tomorrow,but she's actually really,really scary :'( what should i do??

i want to get this done and she says it's too difficult and i have the feeling she doesnt like me evn though i'm really polite and everything.and also,i cut my own hair,cuz i'm like so cool y'know?and on monday she did this misceláneo thing making all my hair perfectly straight (i always have my hair curly and messy on top,and straight on botom) and the it showed a bit at the back where i'd cut it bad,cuz i dont actually look at what i'm doing,it doesnt even mostrar until she did that.and i didnt admit to it haha but i still feel that she just..oh i dont know!i dont even wanna go now!!! helppp!and i need it done por saturday when i go and see iron maiden,dk if i'd be able to even book a salon hairdresser thing :(
