As a result of hormone imbalances, over-styling, product usage, dirt, and dust, your scalp and hair may experience an overgrowth of microbes that get trapped, clogging pores at the scalp and damaging hair.



How we address it:

Our scalp mask is a science-backed formula that works to dissolve excess sebum and remove product build-up without stripping the scalp. This helps to balance the scalp microbiome, cultivating the optimal ecosystem for improved hair health.


Control oiliness, dryness, and build-up— for your healthiest scalp and hair.

We’re serious about facts. Ask away.


Can I use Build-Up Blocker instead of Hair Growth Nutraceuticals?

Build-Up Blocker 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 products like Build-Up Blocker with your Hair Growth Nutraceuticals to optimize your hair health.

How do I know if Build-Up Blocker is right for me?

We recommend Build-Up Blocker if you have an oily scalp or regularly use dry shampoo or other styling products. Styling practices, product usage, pollution, and hormone imbalances can cause sebum build-up and clogged pores on the scalp, which can lead to damaged hair.

How do I use Build-Up Blocker?

Apply Build-Up Blocker to wet or dry hair before shampooing. Leave on for 3-5 minutes, then rinse out with water. We recommend using 1-2 times a week for oily hair, or 2-3 times a week for dry hair.

Is Build-Up Blocker safe to use if I have a sensitive scalp or sensitive skin? What about if I am sensitive to fragrances?

This formula has been clinically tested on users with sensitive scalps and is formulated with natural ingredients and natural fragrance. If you have a sensitive scalp, we recommend doing a patch test before incorporating the products into your hair wellness routine.
