I've been using Wen now for about 6 months. I absolutely LOVE it. It may not have the perfect ingredients list but it comes close to other more natural hair products I've used. I wash my hair every other day & I get compliments on how healthy, shiny my hair looks. It feels healthier too. I used Live Clean products before this & they're good... but using Wen means you only used one product & you don't have to wash every day.
I'm not sure whether they're available in the US, but I use Faith in Nature hair products and they're amazing. They're vegan-friendly and made from entirely natural ingredients, and since I started using them my hair's been in the best condition it's ever been in!
I use a product from Lush cosmetics here in Australia called Veganese, a hair conditione, i use a lot of Lush products now! http://www.lush.com.au/shop/product/product/id/656/keyword/vegan/veganese-250g
