The skin's bacteria might influence the development of a hair loss condition called alopecia areata.

Spaceflight changes how genes work in astronauts' hair follicles, possibly affecting hair growth.

Air pollution worsens skin diseases and aging by causing inflammation and oxidative stress.

Newborn mouse skin cells can grow hair and this process can be recreated in adult cells to potentially help with hair loss.

Polyurethane dressings show promise for wound healing but need improvements to adapt better to the healing process.

The document concludes that stem cells and their environments are crucial for skin and hair health and have potential for medical treatments.

Growing human skin cells in a 3D environment can stimulate new hair growth.

Castor oil-based polyurethanes are promising for making safe, strong-performing, eco-friendly hair-styling products.

The new wound dressing promotes cell growth and healing, absorbs wound fluids well, and is biocompatible.

Dandruff is linked to increased T cells and weakened immune protection in hair follicles.

The document concludes that skin biopsies, genetic and environmental factors, and specific treatments are important in managing cutaneous lupus erythematosus.

TCDD disrupts skin stem cells, causing skin issues like chloracne.

The document concludes that understanding adult stem cells and their environments can help improve skin regeneration in the future.

Tofacitinib may be an effective and safe treatment for adolescent alopecia areata.

Melanocytes are diverse cells important for pigmentation and skin health, influenced by genetics and environment.

Resveratrol activates the Nrf2 pathway in human skin, significantly increasing the production and distribution of the antioxidant glutathione.

Certain gene mutations can weaken the skin barrier and, when combined with environmental factors, lead to eczema and severe itching.

Hair fibers break by cuticle cell slipping, shape changing, cuticle fraying, and surface cracking when stretched under specific conditions.

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.

Pollution increases a compound in the skin that can lead to faster aging and more inflammation.

Different parts of the body have unique immune characteristics in their skin.

Melanoma development can be linked to the breakdown of skin's melanin-producing units.

Runners often face skin problems like blisters and infections, and both prevention and early treatment are important.

The yeast found in a sea lion's skin lesion was almost identical to that on healthy skin, suggesting environmental factors may affect fungal growth and the cause of the lesion is unclear.

The document concludes that a deeper understanding of skin aging and photodamage is needed to create better skin treatments.

Athletes need effective management of skin disorders for their performance and well-being.

Urban pollution and sun exposure speed up skin aging and wrinkle formation in Chinese women, with pollution's effects becoming significant after age 45.

The skin is a complex organ that protects the body, regulates temperature, and has roles in immunity, hormone function, and vitamin D metabolism.

Melatonin in the skin helps protect against damage from stress and UV rays, and could be used to treat certain skin conditions.

Estrogen replacement can improve skin health in menopausal women but doesn't reverse sun damage or prevent hair loss.
