Hands down, this is one of the best products I've used for my ever so aggressive dry scalp. Most products have a super strong scent. Being a member of the "wash your hair every 4-5 days" club, this was not the case with other systems like Clear or head & shoulders. Those I could barely deal with the smell as soon as I was out of the shower. This! This is magical! I felt immediate relief as soon as I used it. The leave on treatment is super cooling and feels great as it dries. My only issue with it is, it can leave my hair a bit thick and heavy at the roots, if not distributed well. The bottle says apply 1-4 x a day but I try to stick to once every 2 days or so. I wish it came in a pump similar to their other systems they have, where it is more of a light mist/ spray. I loved the old formula they had in a gold bottle. It was so relieving and didn't make my hair heavy.
