If you do not have curly locks in a colour you need you can make them quite easily.
First take some long thin strands of wool. I found merino or corridale works well.
Wrap these strands around a knitting needle or kebab stick tightly. Then pour some boiling water over the wool. Be careful of your fingers.
Leave somewhere to dry. I just pop mine on top of the radiator out of reach of any pets though.
Once dry unwrap your wool and you have curls.
