This smells really great but I suspect that the intense fragrance is the culprit of the itchiness and scalp irritation I was left with after using this. Also felt the formulation had difficulty cleaning my thick (and long) hair even in comparison to some other SLS-free shampoos. 

Makes no difference, really just an average shampoo what I could have bought in the drugstore for the fraction of the price. I understand the quality ingredients are expensive.

I love it. It doesn’t contain SLS, it’s fungal acne safe and smells delicious (fresh apple smell). My hair loves it too!

I wish I loved this as much as the other reviewers did, but unfortunately, it made my scalp very dry and flaky. The smell is okay, but not something to buy this for. I prefer Philip Kingsley's dry itchy scalp shampoo, which really smells like green apples and is not harsh on my scalp, so if you have a dry-ish scalp I would try that one instead. This one, however, not for me, unfortunately.

The best shampoo ever, so clean combo, amazing for every day and my hair was braking, and this combo with conditioner, is amazing, i will never use something else, already at my 5 bottles!
