Slows Greys | Calms Stress | Oil-Free

The ultimate overnight hair wellness ritual. This limited-edition duo pairs Good Night, Grey® overnight scalp serum with Lunya's iconic silk sleep mask in exclusive Arey green. Together, they create the perfect nighttime routine to support healthier, fuller, more pigmented hair while you sleep.

WHAT IS IT?

 

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.

Powered by clinically studied ingredients, it helps:

  • Support the anagen (growth) phase so hair has more time to grow stronger and fuller
  • Defend against oxidative stress that can contribute 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.

WHAT'S INCLUDED?

 

3 Month Supply of Good Night, Grey® Overnight Scalp Serum (3.38 fl. oz. / 100ml)

1 Small LUNYA Washable Silk Sleep Mask

HOW TO USE

 

Good Night, Grey®: At night, 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.

Lunya Sleep Mask: Slip on after applying Good Night, Grey® to block out light and support deeper, more restorative sleep. The soft, breathable silk is gentle on skin and hair.

    Staple in my routine!

    I’ve been taking Not Today, Grey for over 3 years and love having this product for extra support! Both have really helped slow progression of and reverse greys. I’m 34 and have only had a few scattered grey hairs on my temples. So happy with my results!

    A Noticeable Difference

    I have been battling grays in my mid twenties. By my early thirties I stopped dying my hair because it would grow back within a week. Recently for my birthday I decided to dye it with a demi-permanent dye one more time and purchase Arey products to use. I have seen a notable difference after a month of use. I have less grey make appearances than I have before. The serum is smooth, doesn't leave my hair oily, and is easily absorbed. Coupled with the wash/condition set, I believe this product is reducing gray hair.

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® 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.

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. 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.

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.
