Vitamin D is important for skin health and may affect conditions like psoriasis and hair loss, but more research is needed to understand its role fully.

Stem cells in the hair follicle are regulated by their surrounding environment, which is important for hair growth.

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.

The skin's internal clock affects healing, cancer risk, aging, immunity, and hair growth, and disruptions can harm skin health.

Hibiscus plant extracts may have health benefits like lowering blood pressure and protecting the heart.

Vitamin D has potential benefits for cancer prevention, heart health, diabetes, obesity, muscle function, skin health, and immune function, but clinical results are mixed and more research is needed.

The AUTS2 gene is linked to neurological disorders and may affect human brain development and cognition.

Hair grows faster in the morning and is more vulnerable to damage from radiation due to the internal clock in hair follicle cells.

UV radiation can help sterilize wounds and promote healing but requires careful use to avoid damaging cells.

Skin-derived precursors in hair follicles come from different origins but function similarly.

Chemotherapy often causes temporary hair loss, which is distressing and needs better treatment and support.

People with alopecia areata often have other health issues like skin diseases, metabolic syndrome, stomach infections, lupus, anemia, thyroid problems, mental health issues, vitamin D deficiency, and hearing and eye problems.

Nutraceuticals may improve skin health and protect against aging, but more research is needed on their optimal use and possible health risks.

Notch/CSL signaling controls hair follicle differentiation through Wnt5a and FoxN1.

Oxidative stress affects hair loss in men with androgenetic alopecia.

Melanocytes are crucial for skin pigmentation and can affect conditions like melanoma, vitiligo, and albinism, as well as hair color and hearing.

Researchers identified genes linked to coat color, body size, cashmere production, and high altitude adaptation in goats.

The document concludes that understanding the genes and pathways involved in hair growth is crucial for developing treatments for hair diseases.

Mice studies show that Protein Phosphatase 2A is crucial for cell growth, development, and disease prevention.

Activating the Wnt/β-catenin pathway could lead to new hair loss treatments.

Older adults have a high rate of skin cancers like basal cell carcinoma and melanoma, mainly due to UV exposure and age.

Mutant mice help researchers understand hair growth and related genetic factors.

Skin development in mammals is controlled by key proteins and signals from underlying cells, involving stem cells for maintenance and repair.

A certain smell receptor in hair follicles can affect hair growth when activated by a synthetic sandalwood scent.

Skin has specialized touch receptors that can tell different sensations apart.

Stress hormone corticosterone blocks a growth factor to slow down hair stem cell activity and hair growth.

A20 protein is crucial for normal skin and hair development.

Prostate cancer prevention includes diet changes, supplements, and medications, with more answers expected soon.

Fetal skin cells from a cell bank heal wounds faster and with less scarring than adult cells.

Advanced human skin models improve drug development and could replace animal testing.
