New understanding and treatments for hair loss are improving, but more research is needed.

Hair follicles help skin immune recovery after UVB exposure.

Skin cells release substances important for healing and fighting infection, and understanding these could improve skin disorder treatments.

Skin stem cells interacting with their environment is crucial for maintaining and regenerating skin and hair, and understanding this can help develop new treatments for skin and hair disorders.

Zinc is crucial for skin health and treating various skin disorders.

Different types of skin on mice have unique chemical profiles related to how they grow and react to stress.

Different types of skin cells and immune cells play a role in healing UV-damaged skin, with chronic UV exposure causing lasting damage to certain skin cells.

Wnt signaling is crucial for skin development and hair growth.

Rats can't grow new hair follicles after skin wounds, unlike mice, due to differences in gene expression and response to WNT signaling.

Different types of sun exposure can damage skin cells and affect healing, with chronic exposure being more harmful, and certain immune cells help in the repair process.

Red light promotes hair growth by directly stimulating hair cells and improving cell communication.

The treatment combining docetaxel, cisplatin, and 5-FU is feasible and effective for advanced head and neck cancer.

Pulsed-intense light can significantly reduce hair, with effectiveness depending on treatment number and timing, and has mild side effects.

The reconstructed skin model from hair follicles functions like human skin in processing chemicals and can be used to test ingredient safety.

Tissue expansion is a useful method for reconstructive surgery with good results and room for further enhancement.

Cell death shapes skin stem cell environments, affecting inflammation, repair, and cancer.

Different levels of shear stress affect where cells move and gather in a 3D-printed model, helping to better understand cell behavior in blood vessels.

Skin stem cells are crucial for maintaining and repairing the skin and hair, using a complex mix of signals to do so.

After menopause, women lose a lot of skin collagen, but estrogen replacement might improve skin health.

UVB radiation harms hair growth and health, causing cell death and other changes in human hair follicles.

Radiation mainly affects keratinocyte stem cells, not melanocyte stem cells, causing hair to gray.

The condition called 'acute diffuse and total alopecia of the female scalp' is actually a known condition named alopecia areata incognita.

Researchers found that bulge cells from human hair can grow quickly in culture and have properties of hair follicle stem cells, which could be useful for skin treatments.

Treatment can improve survival and symptoms in dogs with Cushing's disease, but outcomes are unpredictable.

Ionizing radiation causes irreversible skin damage, with single doses leading to acute injury and hair graying, and fractional doses causing more severe long-term tissue damage.

The document concludes that the immune-inhibitory environment of the hair follicle may prevent melanoma development.

Progranulin overexpression leads to shorter, thinner hair and increased cell death in mouse hair follicles.

The document concludes that hair biology is complex and there are still unanswered questions about hair loss and follicle changes.

Ginsenoside Rg1 protects mouse skin from UVB damage and helps control inflammation.

Skin problems are common after stem cell transplants, and early treatment by dermatologists can improve patient outcomes.
