Dermatoscopy and videodermatoscopy are useful for diagnosing and monitoring various skin, hair, and nail conditions.

Guidelines for diagnosing common hair loss include detailed history, clinical examination, and various diagnostic techniques.

Microneedles improve drug delivery in various body parts, are safe and painless, and show promise in cosmetology, vaccination, insulin delivery, and other medical applications.

Matriptase is crucial for keeping epithelial tissues healthy and functioning properly.

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.

Dexamethasone speeds up hair loss in mice, while cyclosporin A slows it down.

Women with PCOS and higher androgen levels are more likely to have fatty liver disease.

New treatments targeting specific genes show promise for treating keratin disorders.

Microneedling is promising for treating various skin issues but needs more research to confirm its effectiveness and safety.
