I've gotten a rash from all the liquid shampoos I've tried. I turned to shampoo bars. I even tried another brand, but I got a rash with about 50% of the types I tried because they added an essential oil fragrance. My son gifted me with a few of these bars that he picked up at a farmers market, and I knew that I was onto something special. There is a mild scent from the herbs used, but it does not trigger my sensitivities. My scalp was calmed by this soap and I have used it exclusively for over a year. I have happy hair and a calm scalp. I follow shampooing with an apple cider vinegar rinse, and my hair has more bounce and texture than it has ever had before! No product build-up -- just clean, natural hair. Thank you Soap of the Earth!
