Cleanse and fortify your scalp microbiome.

What you see and feel:

Oily scalp, dry scalp, sebum build-up, or dirty hair that lacks volume.



What is happening:

Dirt, pollution, dust particles, and styling products clog pores while harsh chemicals (found in common shampoos) over-cleanse the scalp barrier and wipe away healthy microbes. What can happen next: an overproduction of sebum (natural scalp oils) and bad bacteria and fungi between cleansing affect the scalp’s ability to provide nutrients to our hair fibers. 


How we address it:

Our scalp shampoo is a science-backed formula that cleanses away dirt, excess sebum, and impurities—without stripping the scalp—to optimize natural pH levels and balance the scalp microbiome. The result: a hydrated, nourished ecosystem for healthy hair.


Control oiliness and dryness— for your healthiest scalp and hair.

We’re serious about facts. Ask away.

Can I use Root Purifier instead of Hair Growth Nutraceuticals?

Root Purifier will not grow your hair. But, it will balance your scalp microbiome, cultivating the optimal ecosystem for healthy hair. We recommend using Scalp Microbiome Support like Root Purifier with your Hair Growth Nutraceuticals to optimize your hair health.

How often should I wash my hair? Is it best to wait between washes or should I wash my hair every day?

We recommend washing your hair frequently as dirt, pollution, dust particles, and styling products can clog pores and throw off the balance of your scalp microbiome. Root Purifier is gentle enough to be used daily.

What makes Root Purifier better than other shampoos on the market?

Harsh chemicals found in common shampoos over-cleanse the scalp microbiome and strip away healthy microbes—which can cause an overproduction of sebum and an imbalanced scalp pH. Root Purifier washes away dirt, excess sebum, and impurities—without stripping the scalp. It optimizes the scalp’s natural pH levels and regulates oil production while also hydrating and nourishing for a balanced scalp microbiome.

Should Root Purifier be applied to strands as well?

Like with other shampoos, we recommend focusing on the scalp, then running the shampoo through your ends for best results.

How much Root Purifier should I use?

Start with at least a quarter-sized amount and increase how much you use based on the length and texture of your hair.

Are the formulas safe for color-treated hair?

Yes, Build-Up Blocker Mask, Root Purifier Shampoo, and Stress Reliever Essence are all safe and have been tested for color-treated hair.

Do I not need to condition my hair when I use these products? Is there a conditioner you recommend?

We recommend conditioning your hair with your preferred conditioner while using these products. Stay tuned for future product launches.
