Season 7, Episode 3: Oral vs Topical Minoxidil for Androgenetic Alopecia
Tuesday May 07, 2024
Tuesday May 07, 2024
In this episode of the Evidence-Based Hair Podcast hair loss specialist Dr. Jeff Donovan breaks down the findings of a recent study comparing oral minoxidil and topical minoxidil in the treatment of male androgenetic alopecia. Published in JAMA Dermatology, the study challenged popular opinions by revealing similar performance between the two types of minoxidil, putting a spotlight on the importance of robust evidence from randomized controlled trials.
Interestingly, Dr. Donovan examined the historical usage of oral minoxidil, once a blood pressure medication, in treating hair loss and the subsequent need for more rigorous studies to solidify its effectiveness. The episode also covers the surprising conclusion that oral minoxidil did not significantly outperform its topical counterpart, contrary to what the mainstream assumes.
Diving deeper into the debate, Dr. Donovan explored differing perspectives derived from the Pantchprateep et al and Penha et al studies of oral minoxidil. Where the Panchaprateep et al study suggested that all patients saw some improvement, the Penha et al study showed that not all participants experienced the same positive results.
In an in-depth examination of the 'Oral Minoxidil versus Topical Minoxidil for Male Androgenetic Alopecia: A Randomized Clinical Trial', the potential side effects, including minor adverse effects of both treatments were also discussed. While not definitive in recommending one treatment over the other, the episode sparks stimulating discussions around the efficacy of oral minoxidil, its comparison to topical minoxidil, and the potential of randomized controlled trials in determining the optimal treatment for male androgenetic hair loss.

Season 7, Episode 2: Drug-Induced Alopecia Areata
Sunday Apr 28, 2024
Sunday Apr 28, 2024
This episode is dedicated to a fascinating subject – drug-induced alopecia areata. In addition to genetic factors, alopecia areata is also influenced by environmental factors such as infections and medications. In this episode, Dr Donovan highlights two studies: “A Cross-Sectional Analysis of Medications Used by Patients Reporting Alopecia Areata on the FDA Adverse Events Reporting System” by Ravapati et al and “Drug-Induced Alopecia Areata: A Systematic Review” by Ezemma et al. These studies present an intensive exploration of drugs possibly causing alopecia areata.
Studies show that monoclonal antibodies are common culprits, and reports of drug-induced alopecia areata are rising every over time.
Surprisingly, it has been observed that the onset of drug-induced alopecia areata could be delayed by as much as a year. Also, patients who discontinued the alleged drug stimulating alopecia areata experienced regrowth of hair, while those who didn't, failed unless treated.

Welcome to a new episode of the Evidence-Based Hair Podcast, where we discuss some questions surrounding the relationship between dupilumab and lymphoma. This episode dives deep into a study by Hasan and colleagues that explores the fascinating and somewhat controversial relationship between Dupilumab, a drug often used to treat atopic dermatitis patients with alopecia areata, and an increased risk of Cutaneous T-Cell Lymphoma (CTCL). Despite its potential benefits, does Dupilumab truly cause CTCL, or does it simply unmask the disease in patients who were previously misdiagnosed?
Using information from a vast database, authors examined whether patients using dupilumab showed an increased incidence of CTCL compared to those who did not. Findings suggest that users of the drug have a four-fold increased risk of CTCL.
While uncertainties remain on whether Dupilumab triggers lymphomas, causes benign lymphoid reactions, or accelerates existing CTCL, this episode underscores the drug's potential risks and the importance of careful diagnostics before prescribing it.
As we continue to gather data and debate the varying viewpoints, we invite you to join us in disentangling the complex relationship between Dupilumab and CTCL. Stay tuned for our next episode, where we explore drug-induced alopecia areata and the potential triggering effects of new monoclonal antibodies.
