Haircare made simple through science.

Allison Harr is making haircare simple through science with Gemma Labs. PSL had been working on the idea of a direct-to-consumer haircare business but had little expertise in the area. Allison came with years of consumer packaged goods experience, and a strong vision for how haircare could be an easy, friendly, and personalized subscription. Together with the design, engineering, and supply chain teams at PSL, Allison and her start-up crew are launching Gemma to the world.
