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.

CLINICAL RESULTS

 

After 6 months using To The Root® Scalp Serum and Not Today, Grey Daily Supplement:
88% saw a decrease in new grey hair growth.
13% decrease in grey hair growth vs. a 10% increase in the placebo group.
3× more participants experienced thicker, fuller hair with enhanced shine vs. placebo.

This is the largest and only clinical study focused on the appearance of grey hair to date. Results typically appear in 3–6 months with daily, consistent use.

Results based on a 6-month, randomized, double-blind, placebo-controlled study of the effects of The System on the appearance of grey hair on 173 subjects, ages 28-65, all less than 25% grey. Results determined by blinded clinical counting and/or clinical photo grading.

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

    Stimulate

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

    Safeguard

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

    Nourish

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

    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.

    To The Root® Scalp Serum
    Rated 5 out of 5 stars
    I think it’s working!

    I hit perimenopause a year ago and starting losing a ton of hair. At first I didn’t think there was anything I could do about it but then I invested in an expensive exosome serum and it was reviving an impressive number of follicles and restoring pigment in about a fifth of them. But the exosomes were costing about four hundred dollars a month. Just not sustainable for my budget. Then 2 months ago I found the To The Root serum and having been using it 4-5 days a week and using the exosome serum once a week. I think the To The Root serum is already doing better at restoring pigment. Not sure about reviving as many follicles but I’m going to stick with this routine for at least several more months and I have a lot of hope!

    New growth with less gray!

    Using this serum with both the wash and conditioner consistently, and I’ve seen less gray growth!! Seriously!! It doesn’t bring back pigment of existing gray, but seeing the healthy, pigmented new growth is so relieving! Little to no fragrance and easy on a sensitive scalp.

    Thank you for your incredible review, Makenzie! We're absolutely thrilled to hear that To The Root® Scalp Serum is delivering such amazing results for you when used consistently with Wash and Smooth. Seeing less gray in your new growth is exactly the kind of progress we love to celebrate! You're spot on that while it likely can't change existing white hair because those strands have lost melanin, it can help all the thousands of strands around those! Your dedication to consistent use is paying off, and we're confident you'll continue seeing these fantastic results. Thank you for being such a valued part of our community and for sharing your relieving experience!
