Biofilms in Scarring Alopecias

Biofilm plays a critical role in scarring hair loss by creating a persistent layer of microbial buildup that protects harmful bacteria and fungi on the scalp, making them resistant to conventional treatments. This hidden barrier triggers chronic inflammation and immune responses that gradually damage the hair follicles, contributing to the scarring process. In cases like CCCA or Lichen Planopilaris, the presence of biofilm can stall healing and block regeneration, which is why removing it is essential. Targeted biofilm disruption helps restore a healthier scalp environment, reduce inflammation, and support the potential for hair regrowth in affected areas.
