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 like that this is easy to use - even when I'm tired and don't feel like doing a whole nighttime routine, this takes just a few seconds. It also absorbs well and has never left my hair greasy or gross.

I am using this serum from last 2 weeks. Have not seen any changes in Grey but the overall serum is pretty good and giving me good results. Will be continuing for next 6 months to see the visible results with my Grey.

- MiriamVerified Buyer2 months agoReviewingGood Night, Grey™Rated 5 out of 5 stars26 year old with early greying getting her color back :)
I’ve only been using Good Night Grey for two weeks and I’m honestly impressed! My hair already feels noticeably denser, the new grey’s are definitely slowing down since I’m also using the Arey shower duo, and my scalp feels calm and healthy every morning. It’s super lightweight, completely non-greasy which I appreciate since I have curly hair, and I love that it works while I sleep, zero extra effort! Already ordering my next tube!!!! ❤️

We're so glad the lightweight, non-greasy formula is working perfectly for your curly hair and that you're loving how it works effortlessly while you sleep. We're confident that your continued use will bring even more incredible results.
