Hair loss in men is common, treatable, but not curable.

New effective scar treatments are urgently needed due to the current options' limited success.

Alopecia areata involves immune activation in the scalp, suggesting treatments targeting TH1, TH2, and IL-23 pathways.

Isotretinoin is highly effective in treating severe acne, rosacea, and gram-negative folliculitis.

Different types of skin cells have unique genetic markers that affect how likely they are to spread cancer.

Epidermal stem cells are diverse and vary in activity, playing key roles in skin maintenance and repair.

CDP is crucial for lung and hair follicle cell development.

New insights show Lichen Planopilaris is a rare, scarring hair loss condition, hard to treat, mainly affecting middle-aged women, and significantly impacts mental health.

Some people with pattern hair loss may also have scalp inflammation and scarring similar to lichen planopilaris.

The document concludes that recognizing and treating cutaneous lupus erythematosus early is crucial for managing the skin and potential systemic symptoms.

Tight junctions are key for skin protection and controlling what gets absorbed or passes through the skin.

Different types of stem cells in hair follicles play unique roles in wound healing and hair growth, with some stem cells not originating from existing hair follicles but from non-hair follicle cells. WNT signaling and the Lhx2 factor are key in creating new hair follicles.

Nanoparticles improve drug delivery through the skin but more research is needed on their long-term effects and skin penetration challenges.

Pig skin is a good substitute for human skin to measure drug absorption, but differences in skin structure and enzymes across species must be considered.

The document recommends using both clinical evaluation and various measurement methods to assess skin greasiness, considering factors like temperature and hormones.

Different types of stem cells and their environments are key to skin repair and maintenance.

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.
