Why we stand behind 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.
CLINICAL STUDIES
Independent studies on key actives in Good Night, Grey™ showed measurable improvements in density, pigment, 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% increase in melanin levels in grey hair after 4 months with Ononis Spinosa & Avena Strigosa Extracts
Key ingredients
The Mela-9® Complex: Stimulates melanin synthesis and preserves pigment pathways at the follicle, helping hair keep its natural color.
Spirulina Maxima + Chlorella Emersonii Extracts: Block cortisol receptors at the scalp, reducing stress-driven shedding and supporting your scalp's overnight cellular repair cycle.
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.

What is an undertone?
An undertone is the color beneath the surface of your skin, which never changes (even with a tan). There are three types of undertones:
Pink/Cool
I see red or pink undertones around the perimeter of my face and neck.
My skin burns easily, but barely tans.
My skin looks better in silver jewelry than gold.
Neutral
I see both pink and yellow undertones around the perimeter of my face and neck.
My skin sometimes burns and sometimes tans.
My skin looks good in both gold and silver jewelry.
Yellow/Warm
I see yellow or golden undertones around the perimeter of my face and neck.
My skin rarely burns, but tans easily.
My skin looks better in gold jewelry than silver.

Usage
Before bed:
Shake well.
Apply directly to the scalp using the precision nozzle, focusing on areas of concern.
Massage gently with fingertips or the Arey Scalp Brush to distribute evenly.
Do not rinse. Apply before bed and allow the formula to work overnight.
Aecause 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.
Pro-tip
Use the Arey Scalp Brush before applying to gently part hair and prep the scalp, then again after to stimulate blood circulation.
Keep the bottle visible on your counter. Habits form faster when they’re easy to see.
Breathe in calming lavender + eucalyptus as part of your nighttime ritual.

Arey
Arey | 'a-ray': Derived from the French word arrêt, meaning “stop". Known as The Wrinkle Cream of Haircare™, Arey is the first functional beauty brand to target aging hair with a proactive, science-driven approach. The seedling for Arey originated when our co-founder Allison Conrad saw her first grey hairs, which prompted her to question why there wasn’t an alternative to accepting it, or covering it up with chemical dyes that have been shown to increase the risk of cancer. With a plethora of creams to prevent wrinkles, SPF to protect our skin and exercise regimens to keep our bodies in shape, there simply wasn’t a proactive solution for getting on top of aging hair. Upon discovering that science has shown there is only one gene (IRF4) that accounts for 30% of why we go grey, she began to research vitamins, minerals and antioxidants that could aide in replenishing the body with what it needs to preserve hair pigment and counteract oxidative stress. After creating a daily regimen that included more individual pills than she'd like to admit; she set out to create a single supplement to support hair color. Thus began a journey with her beloved hairstylist Jay Small, who shared the same passion for creating a solution to a problem he's seen many times over with his clients over the past 20 years. Along with a group of talented and experienced medical and scientific professionals, they created an entirely new category in haircare. From a daily supplement to topicals, Arey offers a full line of clean, innovative products formulated with vitamins, minerals, antioxidants and a clinically efficacious peptide to slow and repigment greys- with the added benefit of growing thicker, fuller, softer, and healthier hair.
