I usually don’t use lash primers or conditioners. I got a sample of Jane Iredale PureLash Extender & Conditioner in my Sample Society box last month and decided to try it. It definitely does what it claims: conditions and extends. It makes applying mascara right after easier, quicker, and you don’t need as many coats. After 3 uses, I can already notice a difference in my lashes. They look less dry and almost seem longer. This has made its place in my morning beauty routine.
