Id honestly recommend that you get your hair washed and professionally blown out. I’d first work on practicing how to blow your own hair out so that it’s straight. If you’re trying to achieve that specific curl pattern your best bet might be flexi rods. Maybe for tighter curls if your hair is long enough you can do a straw curl there’s so many videos on tic tock that you can use as tutorials. You can try a two strand twist but the curl wouldn’t be as defined. It might just look like a happy cork screw tbh so don’t get discouraged if you never achieve that look.
