I have oily roots and dry ends, this shampoo is one of the few (3 to be exact) that did not clean my roots. I used 5 handfuls (normally I use 2 or at most 3) and emptied half of the shampoo because it didn't lather. And I'm not referring to the lack of foam, I mean that I felt greasiness on my fingers as I rubbed my roots even on the 5th handful. When I dried my hair, it was patchy and flattened at the roots, I had intense frizz and when I scratched my head, I had dandruff from the buildup on my nails. You can strongly feel the mint "burning" when you have it on your head (which personally I like), it smells strongly of tea tree (which personally I don't like) to the point that my eyes were slightly tearing/irritated. I do not recommend it, especially for very dry hair.
