Curl Science by Curl Centric

Curl Science by Curl Centric

Curl Science checks popular hair advice against the research, one question at a time. Does rice water help your hair grow? Does the porosity float test work? Why does your hair keep breaking no matter what you do? Each weekly episode runs about six minutes, covers every curl type from 2A to 4C, and ends with what you’ll want to try on your next wash day. The show comes from Kenneth and Kira Byrd, the husband-and-wife team who have run Curl Centric since 2008. Researched and written by Curl Centric. Read by an AI voice.
