The best I have used for hair damage and volumizing in one is Biolage. It runs about $15 a bottle. It is completely worth it though.

Use a good thermal protectant spray before flat ironing or curling. Studio Line has a good one.
I use Frizz Ease Hair serum. I also use John Freida products.
I like BioSilk Silk Therapy. ThermaSilk products are great, too.
