WHAT IS IT?

 

To The Root® is designed to support long-term scalp and strand health while adding weightless volume. Powered by our patented Mela-9® Complex—a science-backed blend of antioxidants and a clinically proven peptide—it helps preserve natural pigment at the source and nourish follicles for thicker, fuller hair. This non-greasy formula suits all hair types and won’t weigh down roots. Most see stronger, healthier hair within 3–6 months with daily, consistent use. Color-safe, dermatologist-tested and hypoallergenic.

HOW TO USE

 

1. Apply daily to the scalp on wet or dry hair.
2. Part into sections and apply 1–3 pumps per targeted area.
3. Massage in; do not rinse. Let absorb, then style as usual.

Pro Tip: For optimal results in slowing greys and supporting repigmentation, pair with Not Today, Grey, our daily supplement, and use both daily for 3–6 months.

How to Apply

To The Root® utilizes a clinically effective peptide combined with powerful antioxidants to preserve hair’s natural color and help repigment greying strands.

HOW TO USE:
  • Apply on wet or dry hair.
  • Create a part, and pump the serum directly onto your scalp.
  • Apply 3-4 pumps to areas of concern 1-2 times per day.
  • You can also pump the serum onto your fingertips to get harder to reach areas.
  • Gently massage in.
  • Allow serum to absorb in for 10 minutes, then blow dry or let hair dry naturally.

How It Works

TO THE ROOT® SERUM

  • Stimulate

    A clinically efficacious peptide helps with repigmentation by stimulating the MC1-R (melanocortin 1 receptor).

  • Safeguard

    Antioxidants including Fo-Ti and sesame seed help reduce oxidative stress in the hair bulb.

  • Nourish

    Extracts from wasabi, ginseng, soybeans and hops provide nourishment to the roots and promote cell turnover to create healthier hair.

  • Volumize

    Pantothenic acid (B5), provides anti-inflammatory properties and is involved in activating the proliferation of cells in the skin barrier and also helps bind water to the skin, adding shine.

    Love it!

    I was afraid at first that this would make me need to wash my hair more often by making it look dirty or crusty, no way! Not only am I reassured that I'm staying consistent with the system by using the serum along with the supplement, it also keeps me consistent with a daily gua sha type scalp massage that's also great for scalp health. The new nozzle is incredibly helpful with direct application. Give it a try!

    So far so good

    I have purchased this product a few times but I not a fan of the pump and liquid version. That would get on my clothes and then I would stop using it. The new version that is like a mist is excellent and makes my hair look fuller and feel softer.

    Please do not add rosemary to this product, I read a review where that was suggested but some of us are allergic to rosemary. I have tried that in several different products and the result was lots of itching so please be cautious about adding anything more to an already great product.
