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. While traditional treatments like isotretinoin and antibiotics offer relief for some, they aren't always effective. The study discusses a case where upadacitinib brought significant improvement after conventional options were exhausted.
Dr. Donovan provides a comprehensive overview of the study, emphasizing the potential of JAK inhibitors as third-line treatments in managing persistent dissecting cellulitis. He also shares insights on the broader implications for future research and treatment strategies.
Join Dr. Donovan next week for an analysis of a study on alopecia areata and cardiovascular comorbidities, and don't miss the annual "Top 20 of 2024" event on December 30th. For more information about the Donovan Hair Academy's programs, visit their website.

Welcome to the latest episode of the Evidence-Based Hair Podcast, hosted by dermatologist and hair loss specialist, Dr. Jeff Donovan. As the director of the Donovan Hair Academy, Dr. Donovan is committed to educating both the public and hair loss practitioners through comprehensive programs like the Evidence-Based Hair Fellowship (EBHF).
In this episode, Dr. Donovan delves into a compelling case report from JAAD Case Reports that explores the use of diphencyprone (DPCP) for treating alopecia areata during pregnancy. Traditionally contraindicated in pregnancy, DPCP is a topical treatment that induces an allergic reaction on the scalp to promote hair regrowth in patients with alopecia areata. Dr. Donovan discusses a unique case where a patient opted to continue DPCP treatment during her pregnancies, resulting in minimal hair loss without any adverse effects on her pregnancies or babies.
Dr. Donovan emphasizes the significance of this study in contributing to the limited data available on DPCP use during pregnancy. While the findings are promising, he cautions that more research is needed before making broad recommendations for DPCP use during pregnancy.
Join Dr. Donovan next week too as he explores the trichoscopy of alopecia neoplastica from breast cancer in another enlightening episode of the Evidence-Based Hair Podcast. Don't miss this opportunity to expand your knowledge and engage in meaningful discussions about hair loss treatment and research.
