    Season 8, Episode 10. Unveiling New Treatments for Dissecting Cellulitis: A Closer Look at Upadacitinib

    Welcome to the Evidence-Based Hair Podcast, hosted by dermatologist and hair loss specialist Dr. Jeff Donovan. In this episode, Dr. Donovan explores a groundbreaking study published in the journal Curious, highlighting the effectiveness of the JAK1 inhibitor, upadacitinib, in treating recalcitrant dissecting cellulitis of the scalp. Dissecting cellulitis, a challenging form of scarring alopecia, often affects males and presents with debilitating symptoms.
