WHAT IS IT?

A three-piece routine that pairs our foundational daily supplement with a pigment-preserving, color-safe shampoo and lightweight conditioner. Not Today, Grey™ feeds follicles from within with a physician-formulated blend of vitamins, minerals, and antioxidants that help defend natural pigment. An easy daily ritual that’s flavorless, gentle, and with no aftertaste. Wash Shampoo delivers our patented Mela-9® Complex (antioxidants + a clinically proven peptide) to the scalp in a sulfate-free, creamy lather that lifts buildup without stripping. Smooth Conditioner finishes with lightweight, strand-strengthening hydration that reduces breakage and locks in moisture for slip, shine, and an air-dry that doesn’t fall flat. Use daily and consistently. Most see visible improvements in 3–6 months, especially in the early stages of greying. Color-safe, dermatologist-tested, and hypoallergenic.

How it Works

Wash Shampoo

Stimulate
A clinically efficacious peptide helps with repigmentation by stimulating the MC1-R (melanocortin 1 receptor).
Prepare
Wasabi extract, sesame seed extract and zanthoxylum bungeanum fruit extract work to help the active ingredients penetrate the scalp and access the follicle
Nourish
Ginseng, fo-ti and caffeine provide nourishment to the root to promote cell turnover and promote healthier hair growth
Volumize
Panthenol plays a role in activating the proliferation of cells in the skin barrier, and also helps bind water to the skin and hair, balancing and adding volume

Smooth Conditioner

Nourish
Hydrolyzed barley protein and coffee extract work together to build internal strength in the hair strand
Protect
Jojoba and shea butter work to seal the cuticle and protect the hair from heat and environmental stress
Volumize
Panthenol actively attracts and retains moisture in the hair strand, helping it look and feel more volumized

Not Today, Grey™

Absorb
Vitamins B6 and B9 optimize body function, setting a foundation for Arey's other ingredients to take effect.
Create
Vitamin B5 promotes cell turnover and Selenium builds a defense against free radicals.
Energize
Vitamin B12 and the Chinese herb Fo Ti fuel Melanin production, while Iron supports the production of red blood cells.
Protect
Paba, Vitamin D & Copper help to protect your natural hair from premature grey, while Vitamin B7 improves the protein structure of hair.

Not Today, Grey™
Rated 5 out of 5 stars
I'm 26 and was getting 2-6 super white hairs a week, now light greys if any
I was starting to noice I was getting really white grey hairs 6 months ago. I thought maybe because of my age, it could be a vitamin deficiency, and gave Arey a shot. After finishing the first month, I noticed a difference in my hair.
My hair is thicker, healthier, and most importantly the white hairs have diminished. I less white, more grey hair and less frequently than I had been. I recommend this to all my friends around my are who are starting to see greys or just concerned about their hair health in general.

The Shower Duo
Rated 5 out of 5 stars
Love using the shower duo
The shampoo and conditioner work really well. I’ve been using the duo, along with the capsules, daily for almost a year now, and I noticed my hair was visibly shinier, manageable, and more healthy looking almost immediately. I notice a difference when I have to use a different shampoo/conditioner, and it bounces back as soon as I go back to the duo. My grays are more blended and much less noticeable now.
