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.

Yes. This product holds The Seal of Approval by the National Eczema Association.

    Best Thing I’ve Ever Found!

    I have chronic issues with irritated scalp and subsequent hair loss due to allergies, eczema, etc.

    For the first time in my adult life, instead of turning to the dermatologist for yet another topical steroid prescription, I am literally able to use this serum instead. I have never found anything over-the-counter so soothing for my scalp like this before and I am over the moon about my results!

    Amazing

    I have eczema on my scalp, neck and upper back and these products have changed my life. I was rapidly losing my hair and had bumps and reactions everywhere. Two months of daily use and my hair is thicker, growing back where it had disappeared and my eczema is starting to fade. I’m never not using this!

    Amazing Results

    The shampoo cleanses gently and soothes my itchy scalp. The conditioner smooths without weighing hair down. I have gray, frizzy hair and these products literally transform it. A little product goes a long way, so there’s no need to replace very often. Love the fragrance free products in this line.
