I have dry, thick, coarse and prone-to-frizz hair. I've used other brands (e.g. Aveda, O&M, Davines) and been happy-ish with them... but this shampoo is the best I have ever used. The best. It foams up extremely well with even a small amount, it smells nice, and after I rinse it out my hair feels soft, untangled and clean. Amazing shampoo!
