TO THE ROOT™
Powered by Mela-9™ Complex, this clean, oil-free serum penetrates deep to slow greying, boost repigmentation, and strengthen strands for visibly healthier hair.
Arey is redefining haircare with a science-backed approach to ageing hair. Co-founded by Allison Conrad and hairstylist Jay Small, the brand was born from a desire to offer an alternative to chemical dyes—one that supports hair from within. Combining vitamins, minerals, antioxidants, and a clinically efficacious peptide, the brand’s range includes supplements and topicals designed to slow and repigment greys while promoting thicker, fuller, and healthier hair. Each formula is designed with clean, effective ingredients to support hair health at every stage.

TO THE ROOT™ SERUM:
Apply liberally on wet or dry scalp or beard 1-2 times daily. Distribute evenly by gently massaging into skin with fingertips and allow to dry. *Results may vary. To The Root™ is most effective when used early in the greying process. Because hair growth cycles take at least 1 to 4 months, it may take a few months before you see results.
