To be straight, try a blow out with a hair dryer, then use a flat iron. Use a heat protectant and not too high a heat, nothing over 300 I'd say.for loose curls, maybe some medium to large size flexirods and set your hair with those?
The keratin treatment can loosen curls, but it can be quite damaging to hair.
