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.

    Frizzy hair

    This product has left my hair so much more manageable. My hair doesn’t feel weighed down anymore, but the frizz is more controlled.

    The scalp duo unscented

    My skin had been breaking out in hives around my face and jawline and I thought the culprit could be the scents in my drug store hair products so I switched to the unscented scalp duo and have had fewer itchy spots on my face! I think my hair looks better too but I really tried it for skin reactions, so I am happy to say those have decreased.

    Scalp duo

    Finally a shampoo that does not irritate! Conditioner might be irritating scalp if applied to scalp. Hoping shampoo doesn't start drying like others have experienced. Dermatologist has said scalp looks healthy but most every shampoo irritates me and I experience bad oiliness and irritation if I don't shampoo every day. Hoping at some point I can go to every other day with these products. Customer service has been wonderful answering questions. Only complaint is the packaging. Hard to dispense the amount of shampoo I want. I did need travel size containers for traveling, so I have just been using those instead.
