How can I straighten my hair?

Hm, that’s a tough question to answer. Let me ask you a few questions to help me understand. Do you want it very straight, or do you have any particular style you’re aiming for?

I want silky straight hair.  My hair is wavy now.
user
Hmm.  If you mean silky straight hair, and you mean it in the sense of being as silky as possible, or if you mean silky straight hair as in a short cut with silky ends, I could try to help you.
