Japanese researchers created new hair follicles from human cells that grew hair when put into mice, and other findings showed a link between eye disease severity and corneal thickness, gene mutations affecting hearing and touch, and the safety of the shingles vaccine for adults over 50.

The document concludes that skin stem cells are important for hair growth and wound healing, and could be used in regenerative medicine.

β-catenin is essential for stem cell activation and proliferation in hair follicles.

β-catenin in the dermal papilla is crucial for normal hair growth and repair.

Telogen effluvium is a reversible hair loss condition that requires a detailed diagnosis and often resolves on its own.

Minoxidil works better for female hair loss, but cyproterone reduces scalp oiliness and causes menstrual issues.

Prolactin contributes to hair loss by promoting hair follicle shrinkage and cell death.

Male pattern baldness involves hormones and cell signals affecting hair growth.

Growth factors and cytokines are important for hair growth and could potentially treat hair loss, but more research is needed to overcome challenges before they can be used in treatments.

Androgens block hair growth by disrupting cell signals; targeting GSK-3 may help treat hair loss.

The circadian clock is crucial for tissue renewal and regeneration, affecting stem cell functions and having implications for health and disease.

Wool follicles are complex, involving interactions between different cell types and structures.

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

Procyanidin compounds from grape seeds were found to significantly increase mouse hair growth.

Dermal Papilla cells are a promising tool for evaluating hair growth treatments.

Mice lacking a key DNA methylation enzyme in skin cells have a lower chance of activating stem cells necessary for hair growth, leading to progressive hair loss.

S100A4 and S100A6 proteins may activate stem cells for hair follicle regeneration and could be potential targets for hair loss treatments.

Hirsutism is excessive hair growth in women often caused by polycystic ovarian syndrome, and identifying the cause is important for managing associated health risks.

Hedgehog signaling helps keep hair follicle stem cells the same in both young and old human skin.

Genetics and hormones cause hair loss; finasteride treats it safely.

Antiandrogens, particularly flutamide and CPA, are most effective for treating hirsutism, with long-term use needed for best results.

Ginseng and its compounds may help hair growth and prevent hair loss, but more human trials are needed to confirm this.

PRP injections improve hair density and thickness in women with hair loss.

miR-22, a type of microRNA, controls hair growth and its overproduction can cause hair loss, while its absence can speed up hair growth.

Genes and hormones cause hair loss, with four genes contributing equally.

Effective management of children's hair loss involves accurate diagnosis, various treatments, and supportive care.

Hair follicles offer promising targets for delivering drugs to treat hair and skin conditions.

Androgens prevent hair growth by changing Wnt signals in cells.

The conclusion is that understanding how feathers and hairs pattern can help in developing hair regeneration treatments.

α3β1-integrin is crucial for maintaining normal hair follicle shape and function but not needed for the development of the surrounding skin.
