Male hormones affect COVID-19 severity and certain drugs targeting these hormones could help reduce the risk.

Finasteride treats enlarged prostate and hair loss, but may cause side effects in some patients.

Low oxygen conditions increase the hair-growing effects of substances from fat-derived stem cells by boosting growth factor release.

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

Hair analysis can detect cocaine use but doesn't accurately show the amount or timing of use.
