WHAT IS IT?

 

Good Night, Grey™ is a first-of-its-kind overnight scalp serum designed to work in sync with your scalp’s natural repair cycle. While you sleep, it supports pigment pathways, improves hair density, and helps counter stress-related damage in the follicle. Think of it as a night cream for your scalp—lightweight, oil-free, and easy to use.

Powered by clinically studied ingredients, it helps:

  • Support the anagen (growth) phase so hair has more time to grow stronger and fuller
  • Defend against cortisol-driven stress that contributes to thinning and greying
  • Support melanin activity at the root to help preserve natural color

And because it’s oil-free and residue-free, it won’t weigh hair down, disrupt your style, or require a morning rinse. Apply at night. Wake up and go.

HOW TO USE

 

Before bed:

  1. Shake well.
  2. Apply directly to the scalp using the precision nozzle, focusing on areas of concern.
  3. Massage gently with fingertips or the Arey Scalp Brush to distribute evenly.
  4. Do not rinse. Apply before bed and allow the formula to work overnight.


Pro Tips:

  1. Keep the bottle visible on your counter. Habits form faster when they’re easy to see.
  2. Breathe in calming lavender + eucalyptus as part of your nighttime ritual.

How to Apply

HOW TO USE:
  • Shake well before each use.
  • Apply directly to the scalp using the precision nozzle. Start from the front of the hairline to the back of your head, focusing on areas of concern like your hairline, natural part, crown, and any visible greying or thinning.
  • Massage gently with your fingertips or the Arey Scalp Brush to distribute the formula evenly and support absorption.
  • Do not rinse. Apply before bed and allow the formula to work overnight. Wake up and style as usual — no morning wash required.

PRO TIPS:
  • Keep the bottle on your nightstand or bathroom counter. Visible reminders build lasting habits.
  • Use the Arey Scalp Brush before applying to gently part hair and prep the scalp, then again after to stimulate blood circulation.
  • Take a moment to breathe in the lavender and eucalyptus scent as part of your nighttime wind-down.

    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.

At night, your body shifts into repair mode: stress hormones like cortisol drop, inflammation decreases, and cells become more receptive to restoration. This is when the scalp is most primed to recover from daily stressors like UV exposure, oxidative damage, and nutrient depletion.

Good Night, Grey™ is designed to take advantage of this window—supporting pigment production, extending the growth phase, and repairing damage that contributes to greying and thinning.

Good Night, Grey™ uses a blend of peptides, antioxidants, and plant extracts to address the biological drivers of greying at night, when follicles are most active.

It helps:

  • Reduce cortisol-related damage that disrupts pigment production
  • Support melanocyte activity during the growth phase
  • Repair oxidative stress that accelerates greying and thinning

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.

Good Night, Grey™ is powered by clinically studied actives, including:

  • Spirulina Maxima & Chlorella Emersonii Extracts – Helps block cortisol receptors, reduce stress-related hair loss, and support overnight cellular repair.
  • Mela-9® Complex (Patented) – Stimulates melanin synthesis, neutralizes free radicals, and helps preserve pigment at the follicle.
  • Red Clover Flower Extract + Biomimetic Peptide – Rich in biochanin A which reduces follicle inflammation and improves anchoring and growth.

Yes. 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.

At night, shake well and apply the nozzle directly to the scalp, gently squeezing to distribute product on areas of concern from the hairline to the back of the head. Massage with your fingertips or the Arey Scalp Brush to distribute evenly.

Do not rinse. This is a leave-in treatment.

No. Good Night, Grey™ is oil-free, fast-absorbing, and residue-free once dry. It won’t weigh hair down or leave buildup on your scalp, pillow, or sheets.

Yes. By helping extend the anagen (growth) phase and supporting follicle anchoring, Good Night, Grey™ can reduce shedding and promote thicker, fuller-looking hair over time.

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 formula is lightweight and suitable for all hair types and textures, including fine, wavy, curly, and chemically treated hair.

Absolutely. Good Night, Grey™ fits seamlessly into your routine and pairs well with Not Today, Grey, To The Root®, and the Shower Duo for a comprehensive approach to aging hair.

Yes. Good Night, Grey™ is vegan, cruelty-free, dermatologist-tested, and scented with 100% natural lavender and eucalyptus for a calming nighttime ritual.
