Great product line
After a decade of trying to solve a really annoying scalp issue I learned about this company on a Dermatology YouTube channel and I figured I had nothing to loose because I had tried every medicated and non medicated hair product on the planet it seemed. I’m happy to say that so far both the unscented shampoo and conditioner and the Rosemary shampoo and conditioner do not aggravate my scalp and as long as I don’t insert any other shampoos in the rotation, my inflammation has completely disappeared! I now keep the shampoos and conditioners on subscription! I love them!!! I’ve been using them for 2 years.
