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.

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!

- SarahVerified Reviewer2 weeks agoReviewingGood Night, Grey®Rated 5 out of 5 starsA 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.
Arey1 week agoThank you for your incredible review, Sarah! We're absolutely thrilled to hear that you're seeing such a noticeable difference after a month of using Good Night, Grey® alongside Wash and Smooth. It's wonderful that you're experiencing less grey, especially after your journey with dyeing. We're so glad that the serum is working perfectly for your hair - smooth, non-oily, and easily absorbed is exactly what we aim for! Your dedication to giving our products a real chance means the world to us, and we're confident that with continued use you'll keep seeing these amazing benefits.
