Can you guys recommend a good natural, or at least semi-natural shampoo? I used Burt's Bees for years, and it was amazingly good, but since the company was bought by Clorox they completely changed their shampoo formulas and now they are awful. I tried a few other brands since then, but I haven't been really happy with any of them. I have mid-back long, straight hair, normal thickness and consistency, so I don't need anything special, but I do practice martial arts and go to the beach regularly. I just need something that actually works. Any recommendations?
