A man's sudden hair loss and color change to white was diagnosed as alopecia areata and it improved on its own after six months.

Hair color is influenced by genetics and can indicate certain health conditions.

Mice treatments didn't grow hair, a patient treatment may affect immune response, and people with hair loss often feel anxious or depressed.

Injections of special skin cells showed potential in treating hair loss, with some participants experiencing increased hair density.

Lifestyle choices like stress, smoking, heavy drinking, sun exposure, and chemical hair treatments might speed up hair loss in people with androgenetic alopecia.

Understanding gene expression in hair follicles can reveal insights into hair growth and disorders.

More dermal papilla cells in hair follicles lead to larger, healthier hair, while fewer cells cause hair thinning and loss.

Minoxidil boosts growth factor in hair cells, potentially promoting hair growth.

Alopecia areata is an autoimmune disease causing patchy hair loss, often with other autoimmune disorders, but its exact causes are unknown.

Androgens can both stimulate and cause hair loss, and understanding their effects is key to treating hair disorders.

Growth factors are crucial for hair development and could help treat hair diseases.

The unit area trichogram is a reliable method to assess hair loss and treatment response in people with androgenic alopecia by measuring hair density and thickness.

Hair loss in androgenetic alopecia is caused by genetic factors and androgen excess, and can be treated with combined therapies.

The p53 protein helps control hair follicle shrinking by promoting cell death in mice.

Msx2 and Foxn1 are both crucial for hair growth and health.

Smad-4 and Smad-7 are key in hair follicle development, with other Smads being less important.

Mice without Vitamin D receptors have hair growth problems because of issues in the hedgehog signaling pathway.

Hormones and their receptors, especially androgens, play a key role in hair growth and disorders like baldness.

Assessing newborn scalp hair can reveal important health information.

New cells are added to the hair's dermal papilla during the active growth phase.

Alopecia Areata is a complex, unpredictable autoimmune hair loss condition with limited treatment options and a significant psychological impact.

The model suggests that scalp tension could lead to hair loss, with factors like blood vessel hardening, enlarged oil glands, and poor microcirculation also playing a role. It also hints at a possible link between skull shape and baldness pattern.

Use 5% minoxidil or oral finasteride for mild-to-moderate hair loss, combine with hair transplant for severe cases.

Wnt/ß-catenin signaling is crucial for regulating skin stem cells and hair growth, with the right levels and timing needed for proper function.

Further research is needed to improve hair regeneration using stem cells and nanomaterials.

In situ DNA labeling in hair can help predict forensic DNA analysis success.

Testosterone affects hair follicles differently across body sites, with beard hair follicles showing more activity of a specific enzyme and presence of androgen receptors compared to scalp hair.

The environment around melanocyte stem cells is key for hair regeneration and color, with certain injuries affecting hair color and potential treatments for pigmentation disorders.

Found microRNA differences in hair cells, suggesting potential treatment targets for hair loss.

Some vitamins and minerals are important for preventing hair loss, but treating hair loss with them without a known deficiency is not proven effective.
