WHAT IS IT?

 

Not Today, Grey™ is your daily internal foundation. Taken just twice a day, this physician-formulated supplement delivers a clinically backed blend of vitamins, minerals, and antioxidants that nourish follicles, support natural pigment production, and promote thicker, fuller hair. Flavorless. No aftertaste. Easy to add to any routine.

Good Night, Grey® is your overnight scalp treatment. This first-of-its-kind lightweight serum syncs with your scalp's natural circadian repair cycle. Supporting melanin pathways, improving density, and defending against the cortisol-driven stress that contributes to thinning and greying. Oil-free, residue-free, and powered by our patented Mela-9® Complex.

Used together, they target greying at two levels: internally with consistent cellular nourishment, and topically during your scalp's peak overnight repair window. The result is a system designed to work harder than either product could alone.

Physician-formulated. Clinically studied. Two pills and a few drops. That's it.

    Rated 5 out of 5 stars
    I like it

    Ive been using the supplement and scalp spray/serum for a few months now (maybe 4 to 6ish, I cant recall). I do feel like it has slowed down the amount of grays coming in. My hair is still mostly dark but but I'll get patches of gray, wirey baby like hairs as I approach 40 and that has slowed down. After a good clarifying shampoo, I do like the serum and my scalp seems hydrated.

    It totally works

    Been on this supplement for 2 years and my greys are gone, and no new white hairs have emerged. I get comments all the time asking where I get my hair dyed :) I kind of wish this was an MLM because I think I’d be in the elite level based on how many people have asked for info on this supplement. I only use the supplement and that has been plenty!

FAQs

Good Night, Grey® is the first-ever overnight treatment designed specifically for aging hair. It works with your scalp’s natural circadian rhythm to reduce stress-related damage, support pigment production, and strengthen follicles while you sleep.

Think of it as night cream for your scalp.

Both products target greying at the scalp but at different times and through different mechanisms.

  • To The Root® is a daily, daytime serum focused on reducing oxidative stress and supporting pigment at the follicle during waking hours.
  • Good Night, Grey® is a nighttime-only treatment designed to work with your body’s repair cycle, addressing stress hormones, inflammation, and overnight follicle recovery.

They can be used together for 24-hour scalp support.

No! Unlike many scalp serums, Good Night, Grey® is completely oil-free. Once dry, 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.

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.

Yes. Every ingredient in Not Today, Grey™ is within the tolerable upper intake level for adults. Our medical and scientific advisors review each ingredient for safety and efficacy. As with any supplement, we recommend checking with your healthcare provider—especially if you take other vitamins or medications.

Not Today, Grey™ is produced in the USA in an NSF-certified, GMP-certified, and FDA-registered facility. Each batch is tested for purity and potency to ensure safety, consistency, and quality, so you can trust what you’re taking daily.

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.

The FDA does not “approve” dietary supplements. However, our manufacturing facilities are FDA-registered and meet rigorous NSF and GMP standards for safety and quality.

Yes, in most cases. The formula was designed to complement common multivitamins, but we recommend consulting your healthcare provider to ensure the combination remains within safe intake levels for your body.

Yes. Not Today, Grey™ was clinically tested with our day time serum, To The Root®. Together, they are 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), To The Root® and Not Today, Grey™ 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.

Independent clinical studies on key ingredients in Good Night, Grey® demonstrated measurable improvements in pigment, density, and follicle health:

  • 89% improvement in the ratio of active growth to shedding phase with Red Clover Flower Extract + Acetyl Tetrapeptide-3
  • 25.9% increase in anagen recovery and 11% improvement in density with Spirulina & Chlorella Extract Complex
  • 47% of participants saw fewer white hairs in 3 months with Palmitoyl Tetrapeptide-20 Amide
  • 40% boost in melanin levels in grey hair after 4 months with Ononis Spinosa & Avena Strigosa Extracts

With consistent nightly use, most people begin seeing visible improvements within 3–6 months, including:

  • Fewer new greys
  • Thicker, fuller hair growth
  • Reduced shedding
  • Softer, shinier strands

As with all hair biology, results depend on consistency and where you are in the greying process.

As with any supplement, we recommend speaking with your doctor before starting Not Today, Grey™ if you’re pregnant or breastfeeding.

Out of an abundance of caution, we do not recommend using Good Night, Grey® during pregnancy or while nursing.

Our other topical formulas such as To The Root®, Wash shampoo and Scrub can help support scalp and hair health during periods like postpartum shedding, when hair needs extra care and consistency.

Yes. Good Night, Grey® is color-safe and does not contain dyes or pigments. It supports your hair’s natural color rather than altering it.

Yes. The formulas are lightweight and suitable for all hair types and textures, including fine, wavy, curly, and chemically treated hair.

Yes. Good Night, Grey® is vegan, cruelty-free, dermatologist-tested, and scented with 100% natural lavender and eucalyptus for a calming nighttime ritual. Not Today, Grey™ is vegan and cruelty-free.
