Skin stem cells are crucial for maintaining and repairing the skin and hair, using a complex mix of signals to do so.

Some breast cancer chemotherapy can cause permanent hair loss.

Hair is important for protection, social interaction, and temperature control, and is made of a growth cycle-influenced follicle and a complex shaft.

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.

Hair loss in Androgenetic Alopecia is caused by genetics, aging, and lifestyle, leading to hair follicle shrinkage and related health risks.

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

Goat reproductive activity and coat growth are affected by light and temperature, with temperature altering prolactin levels and hair growth, but not melatonin or estrus onset.

Mice without certain skin proteins had abnormal skin and hair development.

Blocking the FGF5 gene in sheep leads to more fine wool and active hair follicles due to changes in certain cell signaling pathways.

The HOXC13 gene affects different hair proteins in cashmere goats in varied ways and is controlled by a feedback loop and other factors.

The article concludes that hair loss is a common side effect of drugs treating skin cancer by blocking the hedgehog pathway, but treatment should continue, and more selective drugs might prevent this side effect.

Mutations in Plcd1 and Plcd3 together cause severe hair loss in mice.

The study concluded that changing the culture conditions can cause sika deer skin cells to switch from a flat to a 3D pattern, which is important for creating hair follicles.

A woman with a new PTCH gene mutation has both Gorlin syndrome and severe hair loss.

Low-dose acitretin helps nail psoriasis, stem cells may treat scarring alopecia, Chinese men have lower baldness rates, lateral foldplasty is good for ingrown toenails, hair diameter helps diagnose female baldness, childhood trauma linked to alopecia areata, certain hair-weaving leads to scalp conditions in African American women, and new methods for hair research and understanding hair and sweat gland development were introduced.

Advancements in tissue engineering show promise for hair follicle regeneration to treat hair loss.

Possible new treatments for common hair loss include drugs, stem cells, and improved transplants.

The research found ways to activate melanocyte stem cells for potential treatment of skin depigmentation conditions.

Changthangi goats have specific genes that help produce Pashmina wool.

Pilose antler extract helps hair grow in mice with a type of hair loss by speeding up the growth phase.

Vitamin D receptor is important for regulating hair growth and wound healing in mice.

EGFR helps control how hair grows and forms without needing p53 protein.

Melatonin treatment increases a specific RNA in goat cells that boosts cashmere growth.

Bmpr2 and Acvr2a receptors are crucial for hair retention and color.

Understanding hair growth involves complex factors, and more research is needed to improve treatments for hair loss conditions.

Regulating cell death in hair follicles can help prevent hair loss and promote hair growth.

Skin aging is due to impaired stem cell mobilization or fewer responsive stem cells.

Different types of stem cells and their environments are key to skin repair and maintenance.

A special stem cell fluid can speed up wound healing and hair growth in mice.

Different types of dog hair loss are linked to problems starting the hair growth phase and early hair cycle ending.
