I need a hair cut

I have dead straight black hair,
no wave, no kinks or curls
I wish it had a a wave because it just looks flat and boring without mousse and a full blow dry.
I don't get it trimmed as often as I should, infact i was the last person so cut my hair
(two bunches and hacked off the ends)
so the ends are looking pretty naff

My hair at the moment
