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.

    Scalp savior

    Historically I have needed 5% urea to have a scalp that had any sense of normalcy. I have eczema and severely dry skin. I’ve tired so many products marketed for eczema and scalp psoriasis, dandruff etc. it’s tricky because dandruff and dry scalp are different. After the urea supply chain blockages, I couldn’t get my usual shampoo. Queue the desperate search attempt for a shampoo that would help my chronically dry, tight, flaky scalp. I tried serums, oils, leave in treatments, deep conditioners you name it. This has been the only thing to really help me. I haven’t even been using it for 12 weeks which is the recommended time to see the full results. After one use, my scalp felt a difference. After about a week, things were really looking up. I’ve already recommended to my sister who is in Utah with the dry air. It’s pricy, but it’s worth feeling like my scalp is made of SKIN. No more embarrassing flakes on my black clothes. No more of the hair growth topicals not being able to actually get to my hair because my scalp was covered in dead skin. I don’t even understand how skin can die off and then regenerate so quickly? I use with a shampoo silicone brush. Leave both in for at least a couple minutes. The conditioner makes my hair softer than it has been since I was a teenager?! My hope is that this will also help long term with the thinning I was experiencing because my poor scalp was a barren wasteland. I urge you to try if you have a dry tight scalp that you can feel…

    High Hopes

    I just started using this duo. I color my hair and have for a very long time. Dryness and frizziness, but still maintaining body, has been a long time challenge. Frizziness on the ends is still apparent but I have high hopes that with continued use that will go away. My hair is definitely silkier and breakage is much much less!

    I love these products.

    I enjoy them being fragrance free, they leave my scalp and strands feeling clean but not stripped of moisture. I would like them in a larger size.
