22. Doctor's Orders: Why HOCl Should be in Your Lash Kit (ft. Optometrists @eyestheticsofficial)

In this special episode, Carly and Olivia are joined by optometrists Dr. Gurleen Dhanoa and Dr. Aysha Chaudhry from @eyestheticsofficial for an in-depth conversation about ocular health, lash extensions, and why hypochlorous acid (HOCl) deserves a place in every lash artist’s routine!
We discuss how they became involved in the lash industry, what healthy lash extensions and proper ocular hygiene look like from an eye doctor’s perspective, and the best practices they wish more lash artists would follow. The episode then dives into all things HOCl: what it is, where it comes from, how it can benefit both lash artists and clients, and how to properly store and apply it. They also cover practical topics like HOCl concentration, product shelf life, packaging differences, client aftercare, and even whether artists should consider charging for HOCl treatments as an add-on or just include it in every service.
If you’ve ever wondered how to elevate your lash services with medical-grade eye care practices, this episode is packed with expert insights you won’t want to miss.
