New biopsy techniques and tools improve alopecia diagnosis, and both too much and too little selenium can cause hair loss.

Topical treatments can deliver active molecules to skin stem cells, potentially helping treat skin and hair disorders, including skin cancers and hair loss.

Reflectance confocal microscopy helped tell periorificial dermatitis apart from similar skin conditions.

Pure carbon nanotubes are safe for mice, but impure ones cause immune issues and hair loss.

Stress can worsen skin conditions by affecting hormone levels and immune response.

PDRN, derived from salmon sperm, shows promise in healing wounds, reducing inflammation, and regenerating tissues, but more research is needed to understand its mechanisms and improve its use.
