Best organic shampoo?

my uncle is super eco friendly and he sends me shampoos and conditioners all the time because he's a hairdresser but i know burts bees makes really good ones and they smell delicious. i like the volumizing set and the moisturizing set. eufora i think is another one. im not sure if its organic but they dont do animal testing and i know it has some organic stuff in it. hope this helps!
