Vitamin D3 and its receptor are important for hair growth, and understanding receptors could help treat hair graying and skin cancer.

The 2004 hair research meeting presented new findings on hair cell differentiation, genetic factors in hair loss, hair pigmentation, and potential targeted therapies.

A thorough history and examination are crucial for diagnosing skin diseases, which affect up to a third of people. This includes details about skin lesions, medication, general health, lifestyle, family, and contacts, as well as examining the rash, hair, nails, and mucous membranes. Changes in hair and nails can also indicate other medical and skin disorders.

Researchers found new hair and nail genes, how hair reacts to UV, differences in white and pigmented hair growth, nerve changes in alopecia, treatments for baldness and alopecia, a toenail condition linked to a genetic disorder, and that nail fungus is more common in people with psoriasis.

Possible link between COVID-19 and hair loss; more research needed.

Scientists made working hair follicles using stem cells, helping future hair loss treatments.

The document concludes that better targeted treatments are needed for wound healing, and single-cell technologies may improve cell-based therapies.

Hair follicles can regrow in wounded adult mouse skin using a process like embryo development.

Vitiligo is a skin condition causing white spots, more common in women, often starts before age 20, and can affect mental health.

Melatonin affects many body functions beyond sleep by interacting with specific receptors in various tissues.

Changing the environment around stem cells could help tissue repair, but it's hard to be precise and avoid side effects.

Alopecia Areata is an autoimmune condition causing hair loss with no cure and treatments that often don't work well.

Obesity affects skin health, causing conditions like acanthosis nigricans and may require different treatment approaches.

Understanding phenotypic plasticity is crucial for developing effective cancer therapies.

DNA profiling in forensics has improved, but predicting physical traits and ancestry from DNA has limitations and requires ethical consideration.

Stress can worsen skin and hair conditions by affecting the skin's immune response and hormone levels.

Hair growth phase and certain genes can speed up wound healing, while an inflammatory mediator can slow down new hair growth after a wound. Understanding these factors can improve tissue regeneration during wound healing.

SKPs are similar to adult skin stem cells and could help in skin repair and hair growth.

Super-enhancers controlled by pioneer factors like SOX9 are crucial for stem cell adaptability and identity.

Microspheres about 1.5 micrometers in size can best penetrate hair follicles, potentially reaching important stem cells.

Videodermoscopy improves diagnosis of hair and scalp disorders and may reduce scalp biopsies.

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

Adult stem cells from rat whisker follicles can regenerate hair follicles and sebaceous glands.

Manage vitiligo with treatments, address emotions, and use camouflage techniques.

The skin's layers protect, sense, and regulate the body's internal balance, but can be prone to cancer.

Chemotherapy can cause various skin reactions, with hair loss being the most common, and proper diagnosis and treatment of these reactions are important.

New nanofiber technology improves wound healing by supporting cell growth and delivering treatments directly to the wound.

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

Hair loss and aging are caused by the breakdown of a key protein in hair stem cells.

Stem cells are crucial for skin repair and new treatments for chronic wounds.
