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. An easy daily ritual that’s flavorless, gentle, and with no aftertaste. Working in synergy, they 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.

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.

Why The System is Your Key to Less Grey, More Vibrant Hair

Not Today, Grey

  • Absorb

    Vitamins B6 and B9 optimize body function, setting a foundation for Arey's other ingredients to take effect.

  • Create

    Vitamin B5 promotes cell turnover and Selenium builds a defense against free radicals.

  • Energize

    Vitamin B12 and the Chinese herb Fo Ti fuel Melanin production, while Iron supports the production of red blood cells.

  • Protect

    Paba, Vitamin D & Copper help to protect hair from premature grey, while Vitamin B7 improves the protein structure of hair.

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.

How to Use

The System addresses grey hair from the inside out and the outside in. 

Not Today, Grey addresses grey hair from the inside-out.

HOW TO USE:
  • Taking two Not Today, Grey supplements each day supplies the body with the vitamins, minerals and antioxidants that support production of hair pigment at the cellular level.
  • Tip: Take the supplement after a meal, instead of on an empty stomach.
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.

    Not Today, Grey
    Rated 5 out of 5 stars
    Re-pigmentation did happen!

    ...but then slowed down so initially saw definite re-pigmentation (black hair coming upwards on grey hair). However this slowed down over time and now the grey hair are more static (i.e. no new greys but no new blacks either). I think this is like any other natural product/process and is as expected. Costs a lot to maintain, and i feel if i stop the greys will win again...hence small -0.5 stars for the cost...

    Hi N.S., thank you for taking the time to share your experience with Not Today, Grey. We're glad to hear that you experienced re-pigmentation! Your observation about the process slowing down over time aligns with what we know about the biological process of melanin production. For optimal results, we recommend adding our topical serum, To The Root or Wash shampoo.

    We understand your concern about the cost and the feeling that stopping might allow the greys to return. The biological processes that support hair pigmentation do require consistent nutritional support to maintain their function, which is why we designed Not Today, Grey as a daily supplement.

    We appreciate your honest feedback about both the positive results you've seen and the cost considerations. Thank you for being part of our community and for sharing your detailed experience with us!
