SEP Hair Diagnostic, short for Scalp Evidence Profile, is building a portable record of hair and scalp health for women, starting with pregnancy and postpartum. The app tracks shedding alongside stress, sleep and life events and sets it beside published research, with sources, so women and their doctors can see what is happening over time. SEP is building toward wearable data from devices like Oura and Apple Health, a before your visit summary to bring to a dermatologist, and a community of short videos matched to each woman's hair. App launch is targeted for June 2027, with a companion kit planned for late 2027. SEP is in private testing and is educational, not medical advice.
