How to Apply

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.

How It Works

TO THE ROOT® SERUM

  • Stimulate

    Stimulate

    A clinically efficacious peptide helps with repigmentation by stimulating the MC1-R (melanocortin 1 receptor).
  • Safeguard

    Safeguard

    Antioxidants including Fo-Ti and sesame seed help reduce oxidative stress in the hair bulb.
  • Nourish

    Nourish

    Extracts from wasabi, ginseng, soybeans and hops provide nourishment to the roots and promote cell turnover to create healthier hair.
  • Volumize

    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.

    To The Root® Scalp Serum
    Rated 5 out of 5 stars
    Helps reduce greys!

    I was skeptical about this product initially, but I started incorporating it into my nightly routine before bed. Within about 4 months, I started noticing fewer grey hairs growing in. I started using this when I was less than 10% grey. I wanted to see if using the supplements would boost the results (again I was skeptical), but I felt like the results continue to improve. I’ve been using the system for over 2 years now and have not needed to start coloring my hair. No one believes I still have my natural color at age 49! I’m very satisfied with this product and highly recommend it!

Grey Hair Serum FAQs

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.

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.

1. Apply daily to the scalp on wet or dry hair.
2. Part into sections and apply 1–3 pumps per targeted area.
3. Massage in; do not rinse. Let absorb, then style as usual.

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.

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.

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

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.

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.

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.

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.

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

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.

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.
