WHAT IS IT?

 

The AM to PM Duo combines two clinically-backed scalp serums designed to work in sync with your body's natural rhythms:

To The Root® Scalp Serum (AM) is a lightweight, oil-free daytime treatment powered by our patented Mela-9® Complex. It helps slow grey growth, supports new hair growth and density, and adds weightless volume. All with a residue-free finish that won't disrupt your style.

Good Night, Grey™ Overnight Scalp Serum (PM) is the first-ever nighttime treatment formulated to work with your scalp's circadian rhythm. While you sleep, it blocks cortisol receptors, supports melanin production, and extends the growth phase. Addressing the root causes of greying and thinning when your follicles are most receptive to repair.

Both serums are dermatologist-tested, trichologist-formulated, color-safe, vegan, and free from synthetic fragrances.

THE SCIENCE

 

To The Root® (AM Formula): Contains our patented Mela-9® Complex a science-backed blend of a clinically proven peptide and antioxidants that stimulates melanin synthesis and preserves pigment at the follicle.

Key Actives:

  1. Biomimetic Peptide – Stimulates the MC1-R receptor to support repigmentation
  2. Fo-Ti & Sesame Seed Extract – Antioxidants that reduce oxidative stress in the hair bulb
  3. Ginseng, Caffeine, Sichuan Pepper – Provide nourishment, promote cell turnover, and support circulation
  4. Panthenol (B5) – Adds immediate volume while binding moisture and adding shine

Good Night, Grey™ (PM Formula): Works with Your Scalp's Circadian Rhythm: At night, cortisol drops and cellular repair peaks. Good Night, Grey™ is designed to maximize this overnight window.

Key Actives:

  1. Spirulina Maxima + Chlorella Emersonii Extracts – Block cortisol receptors to reduce stress-related shedding and support overnight cellular repair
  2. Mela-9® Complex (Patented) – Stimulates melanin synthesis and neutralizes free radicals
  3. Red Clover Flower Extract + Acetyl Tetrapeptide-3 – Extends the anagen (growth) phase and strengthens follicle anchoring
  4. 100% Natural Lavender + Eucalyptus – Signals calm to support lower cortisol levels during sleep

WHY THIS WORKS

 

Hair aging is driven by multiple biological pathways, including oxidative stress, reduced melanin production, and shortening of the hair growth cycle.

The AM to PM Duo targets these processes at different times of day:

  • Day: Protect follicles, preserve pigment, support volume
  • Night: Support cellular repair, melanin production, and growth phase extension
    Together they provide continuous support for healthier hair.

    Wow! Set it and forget it!

    The Goodnight Grey product is awesome. Just a few dabs at night and I go along with my routine. It’s great, easy, and smells good too. I was worried that it would be greasy but it wasn’t at all! I love this product and I’m already seeing some results.

    Thank goodness for this!

    I have lost hair, have breakage, and all of a sudden am going grey! For once I’m glad to have a product that visibly helps with all. Much better than Kerastase overnight serum, will repurchase!

    Miracle worker

    I bought this product on a whim and didnt expect a miracle bue it truly has been. I have very fine hair that has been losing density as I get older. This has not only improved the density and thickness of my hair but it’s light enough that my hair doesn’t feel weighed down, which is a problem I experience with a lot of other brands. It doesn’t leave a weird residue which minimizes the frequency I need to use a clarifying shampoo. I’m already starting to see a lot of new growth come in and I’ve only been using this product for about 6 weeks. I’m excited to see my results after I’ve used it for multiple months!

    Thank you for your wonderful review, Carmen! We're absolutely thrilled to hear that Good Night, Grey™ has been such a miracle worker for you. It's fantastic that you're experiencing improved density and thickness in your fine hair after just 6 weeks - that's such promising progress! We're so happy that the lightweight formula works perfectly for your hair type without weighing it down or leaving any residue, as we know how challenging it can be to find products that deliver results without those heavy, sticky side effects that so many other brands have. Seeing new growth already is incredibly exciting, and we're confident that your continued dedication over the coming months will bring you even more amazing transformations!

    WOW wish I could have started using this ages ago

    I’ve been struggling with shedding and hair thinning at my temples for the last two years. I’ve tried a ton of other topical solutions but never got the results I was looking for and my hair was always so oily I would have to have dirty sticky hair if I really wanted to maintain the routine. This product is SO MUCH BETTER than everything else I’ve tried. First of all, there’s no residue when I apply and massage into my scalp, I can barely tell I have product in. I’ve also seen a significant reduction in shedding volume since I started using this the last 4 weeks and am starting to see baby hairs pop up all over my temple area where I have been focusing the treatment. I can’t wait to see what my hair looks like after a few more months of use

    Arey gets it right

    Like many people using Good Night Grey, I’m in a phase of life where there’s a lot going on - and not much time for elaborate self-care routines. This serum takes about one minute to apply at night and, best of all, doesn’t require a shower the next morning. It’s refreshingly simple! I really appreciate how much Arey clearly keeps the customer experience in mind when creating products.

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.

It is a daily scalp serum designed to slow the growth of grey hair, support hair density, and improve overall hair and scalp health.

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

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.

Yes. To The Root® was tested with our daily supplement, Not Today, Grey. 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.

Apply 6 to 8 pumps directly to the scalp on wet or dry hair. Focus on areas of concern such as the hairline, part, and crown. Massage gently using your fingertips or the Arey Scalp Brush. Allow the serum to absorb for about 10 minutes, then style as usual.
