Ronex Cosmetics Inc.

Ronex Cosmetics began in 2011 as a small formulation lab in Boston. The founding team came from cosmetic chemistry and product development, and they shared one frustration: scalp care was full of loud promises and very little clear information about what was actually in the bottle.

For years the team worked behind the scenes on topical solutions, testing how ingredients stay stable, how they feel on the scalp and how a routine fits into a normal morning and evening. When research on clascoterone started getting attention, the team set out to build a simple, well made daily scalp-care solution around it. That became ClascoteroneX.

Today the same Boston team develops the formula, writes the information on this site and answers your emails. We are a small company on purpose: no call centre, no resellers, just people who know the product and reply within 1 business day.

Ronex Cosmetics Inc. works as a research and development company in cosmetic science. Its work centres on topical scalp-care formulations — how active ingredients behave on the scalp, how they are stabilised in a solution, and how they are delivered in a precise daily routine.

The result of that work is ClascoteroneX: a clascoterone 5% w/v topical solution in a 90 mL bottle with a calibrated dropper, applied 1.5 mL twice daily. One bottle covers approximately 30 days.

The company sells directly to customers through this website and handles its own customer support, shipping and returns. Returns go to the Boston address above.
