This starter bundle pairs our Good Night, Grey® Overnight Scalp Serum with the Arey Scalp Brush and Lunya's iconic silk sleep mask in exclusive Arey green. Everything you need to transform bedtime into your most powerful hair wellness routine.

WHAT IS IT?

 

The ultimate starter set for overnight hair wellness. Good Night, Grey® is an overnight scalp serum designed for aging hair and pigment support. It works by supporting the scalp, addressing stress-related damage, improve pigment production, and strengthen follicles, all while you sleep. Think of it as night cream for your scalp. The Arey Scalp Brush stimulates blood circulation, lifts buildup, and enhances product absorption with a relaxing mini-massage feel. The Lunya Silk Sleep Mask, reimagined in Arey's signature rich green, blocks out light for deeper, more restorative sleep, when your body (and hair) repairs most effectively. Together, they create a complete nighttime ritual designed to slow greys, reduce stress, and support healthier hair while you sleep.

1 Month Supply of Good Night, Grey® Overnight Scalp Serum (1.35 fl. oz. / 40mL)
1 Small LUNYA Washable Silk Sleep Mask
1 Scalp Brush

Please note: This set does not come pre-kitted in a box. All items are packaged separately.

HOW TO USE

 

Step 1: Prep with the Scalp Brush
Before applying Good Night, Grey®, use the Arey Scalp Brush to detangle hair, create clean partings, and prep your scalp. Move the brush in gentle, slow circles over your entire scalp to boost blood circulation. This also helps open lymphatic drainage and primes your scalp for maximum product absorption.

Step 2: Apply Good Night, Grey®
Shake well and apply nozzle directly to the scalp, gently squeezing the tube to distribute product evenly on areas of concern, working from the hairline to the back of the head. Massage with your fingertips or the Arey Scalp Brush to distribute evenly and stimulate circulation. Do not rinse. Finish by enjoying the clean, calming lavender and eucalyptus scent as part of your wind-down ritual.

Step 3: Sleep with the Silk Mask
Slip on the Lunya Sleep Mask to block out light and support deeper, more restorative sleep. The soft, breathable silk is gentle on skin and hair.

    Good Night, Grey®
    Rated 5 out of 5 stars
    Impressive results!

    I just turned 30 three months ago and noticed my first few grey hairs sprouting up soon after that. Since I’m already working on improving my anti-aging skincare, an anti-aging hair care product seemed worth a try too. I admittedly haven’t used it every single night, and I have pretty short hair + very few greys, so I’ve stretched out my first bottle longer than one month, BUT even my imperfect regimen has apparently already yielded visible results in only two to three months. My hairdresser of several years said this weekend that it’s “the thickest she’s ever seen it”! And my hair was pretty thick to begin with, so I didn’t even think it was possible! I’m not sure how long one bottle will last me because I still have a fair bit left of my current one, but once I know, I might just sign up for a subscription of this stuff. Thanks Arey!

Overnight Hair Serum FAQs

Good Night, Grey® is an overnight scalp serum designed for aging hair and pigment support. It works by supporting the scalp, addressing stress-related damage, improve pigment production, and strengthen follicles, all while you sleep. Think of it as night cream for your scalp.

Good Night, Grey® is designed to work overnight to nourish the hair, maintain natural hair pigmentation and reduce oxidative stress.

Good Night, Grey® uses a blend of peptides, antioxidants, and plant extracts to support antioxidant defenses and pigment pathways associated with greying.

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 support pigment pathways and fuller-looking hair.

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:

  • 88% improvement in the ratio of active growth to shedding phase with Red Clover Flower Extract + Acetyl Tetrapeptide-3*
  • 25.9% increase in anagen density 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**
  • 41% increase in melanin levels in grey hair after 4 months with Ononis Spinosa & Avena Strigosa Extracts
*Based on Capixyl rinse-off data
**Consumer self-assessment

With consistent nightly use, visible results may take 3–6 months. Studies on key ingredients showed improvements in pigment- and density-related measures over this timeframe, though individual results vary based on consistency of use 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. Apply on hair before bed and let it work while you sleep.

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, pillowcase, or sheets.

Yes. Studies on key ingredients show support for anagen-phase parameters, follicle anchoring, and hair-density measures, which may help hair look thicker and fuller 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. For additional support from within, Not Today, Grey is a daily grey hair supplement with vitamins, minerals, and antioxidants to help with healthier-looking hair and support.

Good Night, Grey® is formulated to support the appearance of natural hair color. If you use oral or topical minoxidil, consult your healthcare professional before adding Good Night, Grey™ to your routine, and follow the directions for each product.

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