# Zenagen

> Zenagen is a salon-trusted, science-led hair and scalp care brand built around three product systems for thinning hair, damage and breakage, and color preservation. Often described as "the fusion of beauty and science," and trusted by 30,000+ salons worldwide.

Zenagen was founded by molecular biologist Jared Reynolds to bring scientific clarity to scalp and hair care. Formulations combine clinically proven ingredients with advanced botanical chemistry to support the scalp environment where stronger, fuller-looking hair begins. The brand is organized around a system-first model — each routine combines a shampoo, conditioner, and (optionally) serum or leave-in rather than relying on a single hero SKU. Customers commonly find Zenagen through their stylist, and the review base includes a meaningful share of postpartum hair shedding, stress- and illness-related shedding, telogen effluvium, color-treated hair, and chemically processed hair concerns. Zenagen products are plant-based, color-safe, cruelty-free, vegan, gluten-free, and made in the USA.
