Hair help: Hey hair experts. - Help.com

There are several shampoos and conditioners that can help, but the bottom line is you’ll have to spend quite a bit of time with a straightener to get it like you want it. There aren’t any short cuts - sorry! Make sure you use a treatment to prevent the heat from the straightener from damaging your hair.

Another option is to decide to love your curls!

You need to go get it thinned out. They won’t be removing any length, just cutting back on the fullness.Also use some of pantene leave in conditioner as this will aid in the hair laying down more easily from your scalp.

no shampoo or comditioner will make a huge difference, but will aid in creating softer slightly smoother hair
getting a good cut helps, ask your hairdresser for layers and to thin it out.
using hair straighteners is the only real way to get poker straight hair i’m afraid or you can get your hair chemically straightened, its like a reverse perm but is quite damaging to your hair and can cost alot
good luck!
