WHAT IS IT?

 

Not Today, Grey is our foundational daily supplement designed to support hair health from within. Formulated with a proprietary blend of vitamins, minerals, and antioxidants, it nourishes follicles and helps maintain your hair’s natural pigment.

Clinically proven to slow grey hair growth, support repigmentation, and promote thicker, fuller hair in as little as 3–6 months with consistent daily use when paired with To The Root®. Thoughtfully formulated to fit seamlessly alongside most daily multivitamins and wellness routines, it’s an easy daily ritual that’s flavorless, gentle, and has no aftertaste. Physician-formulated.

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

HOW TO USE IT

 

1. Take 2 capsules daily, preferably with food.
2. Expect visible results in 3–6 months with daily use.

Pro Tip: For maximum results, pair with a topical treatment featuring our patented Mela-9® Complex, like To The Root® Scalp Serum or Wash Shampoo.

CLINICAL RESULTS

 

After 6 months using Not Today, Grey and To The Root® Scalp Serum:
88% saw a decrease in new grey hair growth.
13% decrease in grey hair growth vs. a 10% increase in the placebo group.
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. Our proprietary blend delivers targeted vitamins, minerals, and antioxidants to help address these factors and support long-term pigment preservation.

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.

FAQs

Not Today, Grey is a daily supplement that delivers a targeted blend of vitamins, minerals, and antioxidants that support your hair’s natural pigment production from the inside out. By replenishing key nutrients that decline with age and oxidative stress, it helps slow new grey growth and, in many cases, repigment early greys. Many users also notice thicker, fuller, shinier hair over time.

For best results, pair it with To The Root® serum, which works topically on the scalp to address greying at the follicle level.

  • 1–2 months: Healthier scalp and stronger hair foundation.
  • 2–3 months: Fuller, shinier hair and less shedding.
  • 4–6+ months: Visible slowing of new greys and, for many, repigmentation of early greys.

Consistency matters. Take the supplement daily and pair it with To The Root® for the most comprehensive results.

No. Not Today, Grey targets terminal hair (like scalp and beard hair), which grows for 3–7 years and is affected by nutrient status. Vellus hair (body hair) grows only 1–2 mm and isn’t influenced in the same way. We have not had reports of increased body hair growth.

Greying is a continuous biological process. If you stop taking the supplement, your hair will gradually return to its natural greying pattern. Many customers choose to make it part of their long-term hair health routine, similar to skincare or daily vitamins.

  • Take Not Today, Grey daily — ideally at the same time each day to build a steady routine.
  • Pair it with To The Root® serum, which targets greying at the follicle level for a powerful inside-out and outside-in approach.
  • Stick with it for at least 3–6 months to allow your hair’s natural pigment cycle to respond.
  • Support your routine with gentle, nourishing haircare, like our Wash Shampoo, to protect existing pigment and keep strands healthy.
