I have very thick and course hair. Is there a shampoo that could soften and give my hair some balance? After I shower or wet my hair and then I let it dry, my hair becomes frizzie and dry. Any suggestions would be helpful.

Use less shampoo. It tends to dry hair out. You can also use a daily conditioner.
Anti-frizz product (should be near conditioners in your store), apply it to your damp hair.

You could go to a local hair salon-and I bet they could help you.
