In this study, researchers characterized telogen effluvium observed in 14 patients following a dengue outbreak in Tainan, noting a mean onset time of 2.1 months post-infection.

In this study, researchers observed that approximately 1.15% of dengue fever patients experienced alopecia, predominantly among females. The hairloss usually occurred during the recovery phase and was often identified as telogen effluvium, with lower platelet count and hematocrit levels potentially serving as risk factors.
A 25-year-old experiencing hair thinning all over the body and head, despite using minoxidil and having low vitamin D levels, is advised to seek a second opinion from a dermatologist specializing in hairloss. The likely diagnosis is diffuse alopecia areata, which may require treatment with a JAK inhibitor.
The user is experiencing continued hairloss despite using finasteride, dutasteride, and minoxidil, and is advised to improve diet, check for deficiencies, and consider other treatments like microneedling. Suggestions include sticking with the current regimen, considering a hair transplant, or accepting hairloss and shaving.
Hairloss may be linked to blood flow issues, but DHT is considered the main cause. Treatments used include finasteride, RU58841, minoxidil, vitamin D3, microneedling, and dutasteride, but hairloss persists.
The user has been experiencing sudden and aggressive hair shedding despite using oral dutasteride and topical minoxidil for six years, and recently added topical finasteride without improvement. Possible causes discussed include stress-related hairloss, dietary changes, or high DHT sensitivity, with suggestions to consult a doctor and consider adjusting treatments.
Can a zinc deficiency directly cause hair thinning or increased shedding?Studies link low serum zinc to diffuse shedding and alopecia areata, and severe deficiency states cause hair loss that reverses when zinc is replaced. The evidence is mostly observational, the one supplementation study was small and uncontrolled, and zinc is not a treatment for pattern hair loss.
