Hi I would like to get my hair to look healthier and smoother- I have heard about the keratin treatment, but its so expensive to get done at the salon! Is there something that I can get at- say, Sally Beauty supply, etc... that is cheaper, that i can do at home? I have thick hair thats frizzy, and very dry! I do strighten it alot, but it seems to just kink right up. Any suggestions will help. Thanks!
