I have to thank my regular salon stylist, Naomi for this one. I have sensitive skin that can react to perfumes, dyes, and strong chemicals. When she noticed my dry flaky scalp (yuck), she suggested I trade my drug store shampoo to Wella Calm Sensitive Shampoo. After two weeks of use, I have noticed a difference. My scalp is beginning to “calm” down from my previous shampoo problems. Wella Calm is fragrance-free and my fine hair needs only this for daily shampooing. It is a bit more pricey at $19.78 CA. from my local salon, Alpine Cut and Esthetics, but worth it for me flake and itch-wise.
