Standard 03
Hair Longevity,
Put to the Test
We pair years of hair and scalp know-how with real clinical research to make anti-aging hair care that actually works.
Four rules behind every claim
-
EVALUATED IN EVERYDAY USE
We don't single out ingredients. We study the finished formula, the same way you use it.
-
independently tested
Every study behind an Arey claim is run by a third party for the most unbiased results.
-
defined protocols
You’ll never have to guess if a result came from a 173-person randomized, placebo-controlled trial or a 30-person panel.
-
study results transparency
We label every kind of evidence, from an instrument reading to a participant's answer

173 people. 6 months. Measured against placebo.
A first for grey: an independent, randomized, double-blind study featured participants aged 28 to 65 with under 25% grey hair.
- 88% saw fewer or no new grey hairs
- 13% decrease in grey hair growth (active group)
- 10% increase in grey hair growth (placebo group)
- 3X more participants reported thicker, fuller hair with more shine vs. placebo
The results have been accepted for publication in the Journal of Drugs in Dermatology. Peer review means researchers with no stake in the outcome checked the work before it was published. [CONFIRM] whether it has now published. If so, we need the full citation and this line changes to "published in."
