Nighttime is when hair changes most.
Stress can make it age faster. As cortisol spikes and melanin pathways weaken, hair can become:
greyer
thinner
drier
more brittle
less dense
But it's also when your body does its deepest repair. Good Night, Grey™ was created to work with that cycle — powered by Mela-9®, Red Clover, and Spirulina — to slow greys, improve density, and reduce scalp stress.

Frequently Asked Questions, answered.
How long does it take to see results?
Our clinically validated formulas are most effective with daily consistent use, and in 3-6 months you'll start seeing results.
Are the products color safe?
All of our products are color-safe and gentle so they will not strip your color. Please note that hair dye likely contributes to increase in grey from the high load of oxidative stress, but our products can help to mitigate.
When is the best time to start Arey?
Any time is a good time to start, but earlier is better. Think of Arey like preventative skincare: it's designed to support your hair before signs of aging appear, and works best for those with 0–30% grey. Whether you're being proactive or already seeing signs of aging hair, there's no wrong time to start.
Are the products scented?
Some of our formulas include naturally derived scent from botanical ingredients. Our shampoo and conditioners feature cedar and sage, while Good Night, Grey™ includes eucalyptus and lavender. These are plant-based ingredients chosen for their calming, grounding properties. If you prefer products with our patented Mela-9® Complex without scent, we offer the To The Root® and Calm It Down® serums.
Are the products sulfate-free?
Yes, all of our products are sulfate-free and also do not contain parabens, phthalates, synthetic fragrance, polyethylene glycol, formaldehyde or dyes.

- Elisa R.Verified Buyer1 month agoReviewingGood Night, Grey®Rated 5 out of 5 starsImpressive 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!
