I am absolutely rubbish at doing my hair, I mean really rubbish, I can straighten it, put it in a ponytail and a bun and that's literally it 
I have a big ish night out tomorrow and I'd really like loose curls/wavy hair so I have hoping you might be able to suggest something that is SUPER EASY TO USE to create this (and preferably available on Amazon prime!!)
My hair is the sort that is not curly, not straight, can go a bit frizzy but behaves reasonably well if that's relevant!
