Estrogen Receptor ß (ERß) is the main hormone controller in human skin and hair follicles, not Estrogen Receptor α (ERα) or the Androgen Receptor (AR).

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.

Obesity is linked to various skin problems and may increase the risk of skin cancer.

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

Mice hair growth patterns get more complex with age and can change with events like pregnancy or injury.

Stress can cause hair loss by negatively affecting hair follicles and this effect might be reversed with specific treatments.

Fat cells in the skin help start healing and form important repair cells after injury.

TRP channels in the skin are important for sensation and health, and targeting them could help treat skin disorders.

New targets for making and using brain-synthesized steroids could lead to better treatments for brain disorders and alcoholism.
