What is To The Root®?

It is a daily anti-grey hair serum designed to slow the growth of grey hair, support hair density, and improve overall hair and scalp health.

How does To The Root® work?

The hair serum uses a blend of peptides, antioxidants, and plant extracts to support melanocyte stem cells and reduce oxidative stress, helping to maintain natural hair color.

How long does it take to see results?

Most people start noticing changes like healthier, shinier, fuller hair within 1–3 months of daily use. Visible changes in grey growth and density typically occur over 3–6+ months, depending on the percentage of grey hair, lifestyle factors, and consistency.

Will To The Root® make my hair greasy or weigh it down?

No! Unlike many scalp serums, To The Root® is completely oil-free. Once it dries, there’s no residue, buildup, or stickiness—just clean, lightweight roots. In fact, the formula can actually add volume at the root, making it easy to incorporate into your regular haircare and styling routine.

Is To The Root® safe and tested?

Yes, it is dermatologically tested, vegan, cruelty-free, and made without parabens, phthalates, sulfates, formaldehyde, dyes or fragrances.

Has To The Root® been clinically tested?

Yes. To The Root® was tested with our daily supplement, Not Today, Grey™. Together, they are backed by the largest and only clinical study to date focused on the appearance of grey hair. In a 6-month, randomized, double-blind, placebo-controlled study of 173 participants (ages 28–65, all with less than 25% grey), To The Root® and Not Today, Grey™ showed significant results compared to placebo: 88% saw fewer grey hairs 13% decrease in grey hair growth vs. a 10% increase in the placebo group 3× more participants experienced thicker, fuller hair with enhanced shine compared to placebo Results typically appear within 3–6 months of daily, consistent use, and were determined through blinded clinical counting.

Is To The Root® suitable for my hair type or color?

Yes. All Arey products are safe for all hair types and colors, including textured and color-treated hair. To The Root® works by supporting the hair follicle—not by depositing color—so it’s universally compatible.

Is To The Root® safe to use on color-treated hair?

Absolutely. To The Root® is color-safe and can actually help counteract some of the damage caused by chemical processing. Our antioxidant-rich formulas nourish your scalp and strands to support thicker, healthier hair over time.

Can I use To The Root® with my existing hair products?

Yes, and we encourage it. To The Root® can be layered with your usual haircare and styling products. For best results, pair it with our daily hair supplement , Not Today, Grey™, to support pigment and hair health from the inside-out.

Can I use To The Root® if I’m pregnant or breastfeeding?

To The Root® is generally considered safe for external use if pregnant or breastfeeding.

Is To The Root® a dye or hair color?

No. To The Root® does not contain any dyes or colorants. It works by supporting your body’s natural pigment production, helping extend and restore your hair’s original color rather than covering greys.

Can I use To The Root® to slow grey hair growth on my beard?

Yes. To The Root® is designed for your scalp and your beard. To The Root® is oil-free and hypoallergenic, so it won’t clog your pores or cause any skin irritation. 6-8 pumps of the lightweight formula can be applied 1-2 times a day.

Is To The Root® vegan, cruelty-free, and gluten-free?

Yes. All Arey grey hair products are vegan, cruelty-free, and gluten-free, and made without silicones, parabens, or synthetic dyes.

How to Apply

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.

How It Works

TO THE ROOT® SERUM

Stimulate
A clinically efficacious peptide helps with repigmentation by stimulating the MC1-R (melanocortin 1 receptor).
Safeguard
Antioxidants including Fo-Ti and sesame seed help reduce oxidative stress in the hair bulb.
Nourish
Extracts from wasabi, ginseng, soybeans and hops provide nourishment to the roots and promote cell turnover to create healthier hair.
Volumize
Pantothenic acid (B5), provides anti-inflammatory properties and is involved in activating the proliferation of cells in the skin barrier and also helps bind water to the skin, adding shine.

Seems to stimulate new hair growth
If you continue to use consistently you will see results. It won’t diminish all gray hair, but it does lessen it.

Fantastic - Go Away Grey!
I’ve been using Arey for over a year now. I started noticing a few grey hairs and thought there had to be a product out there that could help minimize the appearance of grey, so I searched online and discovered Arey! Since then, there’s been no turning back. I’m 47, and I feel like my grey hair has barely increased. Beyond that, my hair feels healthier, thicker, and stronger overall. It’s definitely a little expensive, but I justify the cost because coloring my hair regularly would be a heck of a lot more expensive! I’m so glad I found Arey and plan to keep using it.

This works
I have been using this for 3 or 4 years and am happy with it. It has brought color back to a lot of my hair. Not all of it but enough that I still use it. I much prefer using this rather than dying my hair.
