How it works

To The Root® Scalp Serum

    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.

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

FAQs

Good Night, Grey® is the first-ever overnight treatment designed specifically for aging hair. It works with your scalp’s natural circadian rhythm to reduce stress-related damage, support pigment production, and strengthen follicles—while you sleep.

Think of it as night cream for your scalp.

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

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

Both products target greying at the scalp, but at different times and through different mechanisms.  

  • To The Root® is a daily, daytime serum focused on reducing oxidative stress and supporting pigment at the follicle during waking hours.
  • Good Night, Grey® is a nighttime-only treatment designed to support pigment pathways and fuller-looking hair.

Yes. To The Root® was tested with our daily supplement, Not Today, Grey™. Together, they are backed by the first and only double-blind, placebo-controlled clinical study 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.

Independent clinical studies on key ingredients in Good Night, Grey® demonstrated measurable improvements in pigment, density, and follicle health:

  • 88% improvement in the ratio of active growth to shedding phase with Red Clover Flower Extract + Acetyl Tetrapeptide-3*
  • 25.9% increase in anagen density and 11% improvement in density with Spirulina & Chlorella Extract Complex
  • 47% of participants saw fewer white hairs in 3 months with Palmitoyl Tetrapeptide-20 Amide**
  • 41% increase in melanin levels in grey hair after 4 months with Ononis Spinosa & Avena Strigosa Extracts
*Based on Capixyl rinse-off data
**Consumer self-assessment

With consistent nightly use, most people begin seeing visible improvements within 3–6 months, including:

  • Fewer new greys
  • Thicker, fuller hair growth
  • Reduced shedding
  • Softer, shinier strands

As with all hair biology, results depend on consistency and where you are in the greying process.

To The Root®️ (AM Routine):
Apply 6 to 8 pumps directly to the scalp on wet or dry hair. Focus on areas of concern such as the hairline, part, and crown. Massage gently using your fingertips or the Arey Scalp Brush. Allow the serum to absorb for about 10 minutes, then style as usual.

Good Night, Grey®️ (PM Routine):
Shake well before use. Apply directly to the scalp using the precision nozzle from the hairline to the back of the head. Focus on areas showing greying or thinning. Massage gently to distribute. Leave in overnight. Do not rinse. Style as usual in the morning.

Yes. Good Night, Grey® is color-safe and does not contain dyes or pigments. It supports your hair’s natural color rather than altering it.

Yes. The formulas are lightweight and suitable for all hair types and textures, including fine, wavy, curly, and chemically treated hair.

Yes. Good Night, Grey® is vegan, cruelty-free, dermatologist-tested, and scented with 100% natural lavender and eucalyptus for a calming nighttime ritual.
