The Hector Estrada System is all about simplicity. Each hair product is designed to be the only one of its type needed, replacing a shelf full of products. The botanically-based line works for all hair types and is used in smaller quantities, and less frequently, than other high-end products. Because you use less, and use it less often, your hair looks and feels healthier. Free of sulfates or parabens, every product is dermatologist-approved and has been formulated by Hector in collaboration with industry expert and a lab specializing in safe, botanical ingredients. Formulated in San Francisco, the line is manufactured entirely in California.
