What are some straightening creams for curly hair?

I put a smoothing conditioner in my hair after I've

washed it and I don't rinse it out.

It's not like shampoo - you can't see it and it's not

flakey. It makes my hair really soft plus it hangs down.

If you do this just make sure you use an anti-frizz

hairspray. Sometimes my hair looks really soft, but

really frizzy at the same time.
