        I have been searching for this shampoo for years...

        After suddenly developing allergies to a lot of ingredients found in natural shampoos in 2020, I have been trying to find an allergy-free shampoo that also made my hair soft and shiny (not dry). I have tried over a dozen, and this is the first shampoo that did not cause an allergic reaction and makes my hair look and feel healthy.
