how do I say thank-you, to the folks that answered my question. My hair 'thing ' thank-you?

As you resolve the question, say thank you to the people who answered it on the comment box before you click OK.

You may also thank some people by emailing them personally. Go to their profiles and check if they allow emails.

You may also make a comment and say thank you if you forgot to say thank you as you resolve it. It's on the question page, just click Comment.

Like you just did.
