WHAT IS IT?

 

The System is our inside-out and outside-in regimen, pairing our physician-formulated daily supplement with a targeted scalp serum to address hair aging at its root. The serum is powered by our patented Mela-9® Complex, while the supplement combines targeted vitamins, minerals, and antioxidants that nourish from within.

Designed to fit seamlessly alongside most daily multivitamins and wellness routines, this easy ritual is flavorless, gentle, and has no aftertaste. Working in synergy, the two help slow grey hair growth, preserve natural pigment, support repigmentation, and promote thicker, fuller hair. Clinically proven to deliver visible results in 3–6 months with consistent daily use. Color-safe, dermatologist-tested, and hypoallergenic.

Heads up: Our packaging has been slightly updated. Please note that some images may show a previous version.

HOW TO USE

 

Not Today, Grey
1. Take 2 capsules daily, preferably with food.
2. Expect visible results in 3–6 months with daily use.

To The Root® Scalp Serum
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 full-scalp coverage, and to get our Mela-9® Complex into hard-to-reach areas, add Wash Shampoo.

CLINICAL RESULTS

 

After 6 months using The System:
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.

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.

THE SCIENCE

 

Greys aren’t just genetic. Up to 70% of greying is tied to other factors like oxidative stress, nutrient gaps, UV exposure, and environmental stress. The System addresses these drivers from two directions: the scalp serum, powered by the Mela-9® Complex, helps preserve pigment at the follicle, while the supplement’s proprietary blend supplies vitamins, minerals, and antioxidants to stimulate pigment from within. This inside-out approach works to sustain your natural color and healthy density over time.

QUALITY + CERTIFICATIONS

 

The System’s supplement component, Not Today, Grey, is made in the USA in an NSF-certified, GMP-certified, and FDA-registered facility to ensure quality, safety, and consistency. Every batch is produced to meet the highest manufacturing standards and tested for purity and potency.

These certifications ensure the supplement you take daily meets strict safety and quality standards—so you can trust it to deliver the results you expect.

    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!

FAQs

The System is our inside-out and outside-in approach to slowing and repigmenting grey hair.

It pairs Not Today, Grey, our daily supplement, with To The Root®, our topical serum, to target greying at the root causes—oxidative stress, nutrient depletion, and pigment loss.

  • Not Today, Grey replenishes vitamins, minerals, and antioxidants that support healthy pigment production and new hair growth.
  • To The Root® delivers our patented Mela-9® Complex, a clinically validated blend of antioxidants and a peptide that helps slow and repigment greys while supporting thicker, fuller hair.

Consistent daily use is key, which is why we offer up to 25% off subscriptions to help you stay on track.

Results vary by individual. Early greys respond best to repigmentation, and many customers see noticeable darkening of new growth with consistent use. While The System can’t change fully depigmented white hair back to its original shade, it can significantly slow the progression of greying and help repigment strands in the early stages.

Yes. The System is backed by the largest and only clinical study to date focused on the appearance of grey hair.

In a 6-month, randomized, double-blind, placebo-controlled study of 173 participants (ages 28–65, all with less than 25% grey), The System showed significant results compared to placebo:

  • 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 compared to placebo

Results typically appear within 3–6 months of daily, consistent use, and were determined through blinded clinical counting. The study has been accepted for publication in the Journal of Drugs in Dermatology (JDD).

Most people start noticing changes like healthier, shinier, fuller hair within 1–3 months of daily use. Visible changes in grey regrowth and repigmentation typically occur over 3–6+ months, depending on the percentage of grey hair, lifestyle factors, and consistency.

Greying is a progressive biological process, so if you stop taking Not Today, Grey or applying To The Root®, your hair will gradually return to its natural greying pattern over time. Think of The System like a skincare or wellness routine — consistency is key to maintaining results.

Yes. Not Today, Grey is made in the USA in an NSF-certified, GMP-certified, and FDA-registered facility. Every batch is tested for purity and potency, ensuring that the supplement you take daily meets the highest standards for quality, safety, and consistency. These certifications mean you can trust the ingredients and results.

Yes. All Arey products are vegan, cruelty-free, and gluten-free, and made without silicones, parabens, or synthetic dyes.

No! Unlike many scalp serums, To The Root® is completely oil-free. Once it dries, there’s no residue, buildup, or stickiness—just clean, lightweight roots. In fact, the formula can actually add volume at the root, making it easy to incorporate into your regular styling routine.

Yes. All Arey products are safe for all hair types and colors, including textured and color-treated hair. The System works by supporting the hair follicle and pigment cells—not by depositing color—so it’s universally compatible.

Absolutely. The System is color-safe and can actually help counteract some of the damage caused by chemical processing. Our antioxidant-rich formulas nourish your scalp and strands to support thicker, healthier hair over time.

Yes, and we encourage it. The System can be layered with your usual haircare and styling products. For best results, pair it with our Shower Duo (Wash Shampoo + Smooth Conditioner) to help preserve existing pigment and enhance softness, smoothness, and fullness.

We always recommend consulting your doctor before starting any new supplement while pregnant or breastfeeding. While the topical serum is generally considered safe for external use, the supplement contains vitamins and minerals, so it’s best to get personalized guidance from your healthcare provider.

No. The System does not contain any dyes or colorants. It works by supporting your body’s natural pigment production, helping extend and restore your hair’s original color rather than covering greys.
