Answer

Why Is pH Level Mentioned On The Package?

During the formulation process we optimize the pH of the formula. We believe it directly impacts the safety and efficacy of the formula. The pH objective will vary based on product purpose. On the secondary packaging (carton) we provide a pH range. The reason a pH range is indicated is that pH may vary during the manufacturing process and/or slightly change over time. Formula that does not contain enough water, will not have a pH listed.

    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.
