Jill Taft is a mom on a mission. The creator and founder of Logic Product Group, Jill is focused on developing products that are safe for families, pets, and the earth. As a mother of two, she became increasingly interested in reading the labels for the natural products she used on her children. She discovered many questionable ingredients are used in these products, but it wasn"t until her daughter started elementary school that she decided she needed to do something about it. Jill heard other moms in the schoolyard talk in hushed tones about classrooms that were rumored to have active headlice cases. Then it happened. Head Lice infested her daughter"s classroom, and when she checked her hair, Jill"s daughter was no exception. She quickly ran to the pharmacy in a full-blown panic, but all she could find was a chemical-based head lice treatment.
