TLDR HIV-1 may cause increased stem cell death in hair follicles, leading to hair loss.
The study from 2006 examined the link between HIV-1 infection and increased apoptosis in follicular stem cells, which may contribute to diffuse alopecia. Involving 15 HIV-1-infected patients and 12 controls, the research utilized double-staining techniques to detect apoptosis and found that 80% of HIV-1 patients had apoptotic stem cells in their hair follicles compared to 25% of controls. The study suggested that the HIV-1 viral protein R (Vpr) could be causing this increased apoptosis by interfering with the cell cycle and inducing caspase activity. The results indicated that this stem cell apoptosis might be a factor in the hair loss seen in HIV-1-infected individuals, although the study had a small sample size.
