WHAT IS IT?
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.

- Amanda C.Verified Buyer3 days agoReviewingThe Shower DuoRated 5 out of 5 starsI absolutely LOVE these!
I've never used expensive products on my hair, them I turned 40 and knew I needed to do something different, but knew I wasn't ready for color to hide my greys. I've been using this duo for 2 months now and I LOVE it. I'll never go back to cheaper products. My frizz is under control and the texture is SO much smoother! I never have to use a flat iron anymore for my hair to look nice. As for the greys, they seem to be less, but may need more time using this to really tell a difference. Thank you for a wonderful product!!
Arey3 days agoThank you for your wonderful review, Amanda! We're absolutely thrilled to hear that The Shower Duo has made such a transformative difference for your hair after just 2 months. It's fantastic that you're experiencing smoother texture, better frizz control, and that you no longer need to reach for your flat iron - those are exactly the kind of results we love to hear about! We completely understand taking that leap from your usual products, especially at a milestone like turning 40, and we're so glad you chose to invest in your hair health. As for the greys, you're absolutely right that continued consistency will help you see even more noticeable results over time. We appreciate you being a valued member of our community and look forward to continuing to provide you with exceptional haircare solutions tailored to your needs.
- Katherine C.Verified Buyer4 days agoReviewingThe Shower DuoRated 5 out of 5 starsFewer Grays & Healthier Hair
I was starting to notice more gray hair and wanted something that did more than cover it up. I decided to try Arey Wash and Smooth because they’re designed to support natural melanin production, and I’m honestly thrilled with the results. I’m seeing fewer grays, and the graying process has clearly slowed down. As a bonus, my hair looks healthier and feels noticeably thicker. Love it!

The added benefits of healthier, thicker-looking hair are the cherry on top! We're so glad you chose a solution that works with your hair's natural processes rather than just covering up. We appreciate you being a valued member of our community and look forward to continuing to provide you with exceptional haircare solutions tailored to your needs.

Not today, grey capsules have been making a difference in the color of my hair. The percentage of white has been about 80% and after using Not today, grey consistently for 4 months, the percentage of white has dropped to closer to 60%.
Arey3 days agoHi Laurel, thank you for taking the time to share your experience with Not Today, Grey after 4 months of consistent use. We're thrilled to hear that you're seeing such significant results - a reduction from 80% to 60% white hair is really impressive.
Your results are a great example of how the biological process of supporting melanin production can work when given consistent nutritional support over time even in later stages of greying. The fact that you've been using the supplement consistently for 4 months really shows in your results, as these processes do require that ongoing support to function optimally.
We appreciate you sharing such specific details about your progress - this kind of feedback is incredibly valuable for other customers who may be wondering what kind of results they might see with consistent use over time.
Thank you for being part of our community and for sharing your positive experience with us!
