That doesn't involve straightening it every day?
It's curly-ish at the front, graduating to merely wavy round the back.
It doesn't help that I can't grow it longer without it turning into rats tails 
However I can go to sleep with straight hair and get up in the morning and look like I've been electrocuted.
It's currently light blonde but I'm planning on darkening it down a bit this week, but what can I do to make it look ok this summer? I'm thinking I need to embrace the wave at least? - but how??
