I do at least one PT a week and use a lot of products with protein. In the summer, I frequently do two. My hair has never met a protein it didn't like. When I first started lurking on nc.com, I did DT because I thought I should. Once I got to know my hair and the ingredients/products it prefers, I stopped. Don't think I've done a PT since summer of '08, if not before.
Condition of my hair is so good, that the shampoo guy at the salon won't condition (he just doesn't "get" it.)
