Dr Christos Tziotzios, Consultant Dermatologist and Senior Lecturer, is currently based at St. John's Institute of Dermatology, within the Guy's and St. Thomas' Hospitals NHS Foundation Trust, London. He is highly specialised in the treatment of scalp and hair disorders. Dr Tziotzios began his medical education at the University of Cambridge where he graduated with his Bachelors in Medicine and Surgery (MB BChir).

He then went on to do Academic Foundation Training, before being appointed Academic Clinical Fellow in Dermatology at St John's. During his training he undertook a doctorate research degree, examining the molecular pathogenesis of frontal fibrosing alopecia. His work resulted in many high-profile publications in high-impact journals (including Nature Comms). His contribution was further acknowledged with several prizes including the British Association of Dermatologists (BAD) Whimster Prize, the BAD Wycombe Prize, the Royal Society of Medicine Dermatology Research Prize and the NIHR/BAD Award.

He continues to remain active in research. He has been awarded a highly competitive research grant from the Medical Research Council (MRC) the European Academy for Dermatological Research (EADV) and the British Skin Foundation (BSF). Additionally, he is the national Chief Investigator (CI) for the ALLEGRO trials researching novel therapeutics for alopecia areata and has set up the Alopecia+me study, which studies the burden of alopecia. He consistently contributes to medical education by teaching and supervising undergraduate and postgraduate students. He is frequently invited Speaker in conferences globally.
