What is Good Night, Grey™?

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.

What is To The Root®?

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

Will To The Root® or Good Night, Grey™ make my hair greasy or weigh it down?

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.

How is Good Night, Grey™ different from To The Root®?

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.

Is it clinically supported?

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

When will I start to see results?

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.

To The Root®️ (AM Routine): 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. Good Night, Grey™️ (PM Routine): Shake well before use. Apply directly to the scalp using the precision nozzle from the hairline to the back of the head. Focus on areas showing greying or thinning. Massage gently to distribute. Leave in overnight. Do not rinse. Style as usual in the morning.

Is it safe for color-treated hair?

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.

Is it suitable for all hair types?

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

Is it vegan and dermatologist-tested?

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

THE SCIENCE

Key Actives:

Biomimetic Peptide – Stimulates the MC1-R receptor to support repigmentation
Fo-Ti & Sesame Seed Extract – Antioxidants that reduce oxidative stress in the hair bulb
Ginseng, Caffeine, Sichuan Pepper – Provide nourishment, promote cell turnover, and support circulation
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:

Spirulina Maxima + Chlorella Emersonii Extracts – Block cortisol receptors to reduce stress-related shedding and support overnight cellular repair
Mela-9® Complex (Patented) – Stimulates melanin synthesis and neutralizes free radicals
Red Clover Flower Extract + Acetyl Tetrapeptide-3 – Extends the anagen (growth) phase and strengthens follicle anchoring
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.

How it works

To The Root® Scalp Serum

Stimulate
A clinically efficacious peptide helps with repigmentation by stimulating the MC1-R (melanocortin 1 receptor).
Safeguard
Antioxidants including Fo-Ti and sesame seed help reduce oxidative stress in the hair bulb.
Nourish
Extracts from wasabi, ginseng, soybeans and hops provide nourishment to the roots and promote cell turnover to create healthier hair.
Volumize
Pantothenic acid (B5), provides anti-inflammatory properties and is involved in activating the proliferation of cells in the skin barrier and also helps bind water to the skin, adding shine.

Good Night, Grey™

Slow Greys
The Mela-9® Complex stimulates melanin synthesis and preserves pigment pathways at the follicle, helping hair keep its natural color.
De-Stress
Spirulina Maxima + Chlorella Emersonii Extracts block cortisol receptors at the scalp, reducing stress-driven shedding and supporting your scalp's overnight cellular repair cycle.
Strengthen & Grow
Red Clover Flower Extract and a biomimetic peptide extend the anagen (active growth) phase, improve follicle anchoring, and help hair grow in fuller and stronger.
Absorb Overnight
This oil-free and residue-free serum fully absorbs while you sleep. No rinse, no weigh-down. Wake up and go.
Scent with a Purpose
A 100% natural lavender and eucalyptus blend to signal calm to your nervous system as part of a sleep ritual. Lower cortisol at night means healthier hair over time.

How to Use

To The Root^® utilizes a clinically effective peptide combined with powerful antioxidants to preserve hair’s natural color and help repigment greying strands.

HOW TO USE:

Apply on wet or dry hair.
Create a part, and pump the serum directly onto your scalp.
Apply 3-4 pumps to areas of concern 1-2 times per day.
You can also pump the serum onto your fingertips to get harder to reach areas.
Gently massage in.
Allow serum to absorb in for 10 minutes, then blow dry or let hair dry naturally.

How to apply Good Night, Grey overnight scalp serum

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.

Worth Every Penny
I am 56 years old and I got CARDED today at my local liquor store. Maybe it was good lighting, because I still have wrinkles, but the only thing different about me lately is my gray hairs are nearly gone. This stuff works. It took some time, maybe a month or two, but my hair feels thicker, healthier, and the new hair growing in is brown again. It is a miracle. I don't post reviews unless I see real results from a product, but this is a 10/10.
