WHAT IS IT?

 

A four-piece regimen that works in concert: Not Today, Grey™, our daily supplement, 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. On the scalp, To The Root® Serum delivers our patented Mela-9® Complex (antioxidants + a clinically proven peptide) to target pigment preservation and support thicker, fuller growth, while Wash Shampoo layers the same complex into a sulfate-free, creamy lather that lifts buildup without stripping. Smooth Conditioner finishes with lightweight, strand-strengthening care that locks in moisture for slip, shine, and an air-dry that doesn’t fall flat. Together, you get a balanced scalp, stronger strands, and hair that looks denser and more vibrant. For best results, 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.

Heads up: Our packaging has been slightly updated. Please note that some images may show a previous version.

How to Apply

The Essentials Kit addresses grey hair from the inside out and the outside in. 

How to apply Arey Wash shampoo
Wash is a gentle shampoo with proactive ingredients that stimulate pigment production and support hair health.

HOW TO USE:
  • Dispense a silver dollar-size amount into your hand and work the product into a lather.
  • Wet hair and apply to scalp and roots.
  • If more lather is needed, add more water and continue to massage into the scalp.
  • Remember to focus on the back of your head as well.
  • Allow the product to sit on the scalp for several minutes.
  • This allows the active ingredients to fully absorb into the scalp.
  • Rinse thoroughly, and follow with Smooth conditioner.
How to apply Arey Smooth conditioner
Smooth is a nourishing and clean conditioner that helps retain moisture inside the hair strand.

HOW TO USE:
  • It leaves a conditioning barrier to help hair to look healthier without feeling weighed down.
  • Depending on your conditioning needs, apply a quarter to silver dollar size amount to mid shaft and ends.
  • Tip: Conditioners should not be applied on or near the scalp.
  • Smooth can be left on the hair for several minutes for deeper conditioning.
  • Use a wide tooth comb to evenly distribute before rinsing.
  • Best when used with Wash shampoo.

How to use Not Today, Grey™ supplement
Not Today, Grey™ addresses grey hair from the inside-out.

HOW TO USE:
  • Taking two Not Today, Grey™ supplements each day supplies the body with the vitamins, minerals and antioxidants that support production of natural hair pigmentation at the cellular level.
  • Tip: Take the supplement after a meal, instead of on an empty stomach.
How to apply To The Root scalp serum
To The Root® utilizes a clinically effective peptide combined with powerful antioxidants to preserve natural hair color and help repigment greying strands.

HOW TO USE:
  • Apply on wet or dry hair.
  • Create a part, and pump the serum directly onto your scalp.
  • Apply 3-4 pumps to areas of concern 1-2 times per day.
  • You can also pump the serum onto your fingertips to get harder to reach areas.
  • Gently massage in.
  • Allow serum to absorb in for 10 minutes, then blow dry or let hair dry naturally.

    The System
    Rated 5 out of 5 stars
    Worthwhile tools for playing the long game

    Loves: The supplement helps me get in a lot of nutrients I know I don't get in my diet and wanted to take anyways. The spray serum is very easy to dispense and easy to take with me to the gym or while traveling, as it's small and doesn't leak or accidentally spray itself.

    Likes: This system is clinically proven to - at the very least - slow gray hair development. That is helping me trust the process and determine that this system is worthwhile for me. I'm about 2.5 months in so I haven't seen gray hair reversal, but I am accepting that I need to play the long game and am glad I started when I did (age 35, about 20% gray total and 40% by my temples).

    Dislikes: The spray doesn't seem very volumizing to me and can sometimes leave my hair looking flat. Applying it one spray at a time, as close to the scalp as possible, then rubbing it in before moving to a separate part of my hair has helped with that.

    Thank you for your wonderful review, Kelsey! We're thrilled to hear that you're loving the supplement for the added nutrients and finding the serum so convenient for your active lifestyle. It's fantastic that the clinical backing is helping you trust the process - you're absolutely right that this is about playing the long game. At 2.5 months in, you're still in the early stages, so consistency will be key for optimal results. Thanks for sharing that helpful tip about applying the serum one spray at a time close to the scalp - that's exactly the application method we recommend for best results. 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.

FAQs

The Essentials Kit is designed for fine to medium hair and anyone looking for a complete, everyday routine to support hair health and help slow the appearance of greys.

If you have medium to coarse hair or need deeper moisture, we recommend The Restorative Kit, which includes Masque Deep Conditioner instead of Smooth Conditioner.

The Essentials Kit includes four core products:

  • Wash Shampoo – Gently cleanses while supporting scalp health and pigment preservation
  • Smooth Conditioner – A lightweight conditioner that smooths, detangles, and strengthens fine to medium hair
  • To The Root® – A daily scalp serum that targets greying at the follicle with antioxidants and peptides
  • Not Today, Grey™ – A daily supplement that supports natural pigment production from the inside out

Together, they create a full daily system for healthier, more resilient hair.

Both kits support hair health and greying, but they’re tailored by hair type:

  • The Essentials Kit: Best for fine to medium hair and includes Smooth Conditioner for lightweight hydration
  • The Restorative Kit: Best for medium to coarse hair and includes Masque Deep Conditioner for richer, deeper moisture

All other core components remain the same, so you can choose based on your conditioning needs.

  1. Wash Shampoo: Use 3–5 times per week to cleanse the scalp and hair.
  2. Smooth Conditioner: Apply after shampooing from mid-lengths to ends; leave on a few minutes, then rinse.
  3. To The Root®: Apply daily to the scalp, focusing on areas where greys appear first; massage gently.
  4. Not Today, Grey™: Take daily, ideally at the same time each day for consistency.

Yes. The Essentials Kit combines nutrient support, topical follicle care, and moisture-rich conditioning to help:

  • Preserve existing pigment
  • Support healthier follicles
  • Improve density and reduce breakage
  • Enhance softness and manageability

With consistent use:

  • Immediate: Softer, more hydrated hair
  • 1-2 months: Improved strength and reduced breakage
  • 3–6+ months: Fewer new greys and fuller, healthier-looking growth

Results vary based on individual biology and how early you start, but consistency is key.

Absolutely. Many customers layer in:

  • Good Night, Grey® for overnight follicle repair
  • Masque Deep Conditioner as an occasional treatment if hair needs extra moisture
  • The Arey Scalp Brush to improve application and circulation

Yes. All products in The Essentials Kit are color-safe and gentle enough for treated hair, including keratin and other chemical services.

Yes. All products are vegan, cruelty-free, and gluten-free, and made without harsh detergents or synthetic fragrances.

Yes. Not Today, Grey™ is made in the USA in an NSF-certified, GMP-certified, and FDA-registered facility to ensure quality, safety, and consistency.

Every batch is produced to meet strict manufacturing standards and is tested for purity and potency, so you can feel confident taking it daily as part of your routine. All ingredients are included at levels within established tolerable intake ranges for adults.

As with any supplement, we recommend consulting your healthcare provider if you’re pregnant, nursing, or taking other medications.
