TLDR Fluconazole can cause hair loss, but the exact cause is unknown.
In the 2019 study, 12 male Wistar rats were used to investigate fluconazole-induced alopecia, showing a significant increase in the number of hairs in the telogen phase, indicative of telogen effluvium, but no significant changes in retinoic acid levels or retinoid responsive gene expression. In the human cohort, 5 patients with chronic coccidioidomycosis treated with fluconazole experienced alopecia, which abated for most after switching to an alternative triazole, except for one whose alopecia persisted. The study concluded that fluconazole can induce telogen effluvium, but the mechanism is not related to retinoic acid metabolism. The exact molecular mechanisms remain unknown.
