Brett King, MD, PHD
Dr. King was the first dermatologist to show that a class of medicines called Janus kinase (JAK) inhibitors were effective for treatment of alopecia areata, vitiligo, atopic dermatitis (eczema), granuloma annulare, sarcoidosis, lichen planus, and other disorders. He has advanced the use of oral minoxidil for treatment of male and female pattern hair loss (also called androgenetic alopecia) and other forms of hair loss.
After completing his medical training, Dr. King spent 14 years on the full-time faculty at the Yale School of Medicine before recently transitioning to private practice in order to focus on patient care, clinical research and medical education. He has been an investigator in numerous clinical trials, including those leading to approval of Olumiant, Litfulo and Leqselvi for treatment of alopecia areata. He lectures nationally and internationally and publishes extensively.
Dr. King was named an American Academy of Dermatology (AAD) “Patient Care Hero” for his work treating patients with severe alopecia areata.
