Frequently Asked Questions
What is To The Root®?
It is a daily scalp 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 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 do I apply To The Root®?
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.
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 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.
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 it 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 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.
