TLDR External factors like certain shampoos, bacterial infections, and parasites might cause hair defects similar to genetic conditions.
The document discussed acquired hair shaft abnormalities that resembled genetic trichorrhexis nodosa in two patients. The contributing factors might have included the use of selenium shampoo and bacterial infection with trichomycosis axillaris. Additionally, there was a possibility that strongyloides larvae caused trichonodosis in one of the patients.
