New hair can grow from large wounds in mice, but less so as they age, involving reprogramming of skin cells and specific molecular pathways.

Hair follicle stem cells can form both hair follicles and skin.

Adult mouse skin contains stem cells that can create new hair, skin, and oil glands.

Ultraviolet rays damage hair, smoking may cause hair loss, and good nutrition is important for hair health, but genetics mainly decide hair thickness.

Mouse hair follicle cells briefly grow during the early hair growth phase, showing that these cells are important for starting the hair cycle.

Chemotherapy often causes hair loss, which usually grows back within 3 to 6 months, but there's no effective treatment to prevent it.

Hair growth can be stimulated by combining certain skin cells, which can rejuvenate old cells and cause them to specialize in hair follicle creation.

Tooth papilla cells can help regenerate hair follicles and grow hair.

Skin stem cells maintain and repair the outer layer of skin, with some types being essential for healing wounds.

Hair follicle cells help maintain and support stem cells and blood cell formation.

Oxidative stress contributes to hair graying and loss as we age.

Certain natural products may help stimulate hair growth by affecting stem cell activity in the scalp.

Human hair follicle cells can grow hair when put into mouse skin if they stay in contact with mouse cells.

A substance called epidermal growth factor helps increase the growth of important hair follicle cells by activating a specific cell communication route.

Researchers successfully grew hair follicle stem cells from mice and humans, which could be useful for tissue engineering and regenerative medicine.

Bioengineering can potentially treat hair loss by regenerating hair follicles and cloning hair, but the process is complex and needs more research.

Sebaceous glands can heal and regenerate after injury using their own stem cells and help from hair follicle cells.

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.

Androgens can both increase and decrease hair growth in different parts of the body.

Red deer only have androgen receptors in neck hair cells for mane growth during breeding season.

Hair ages due to various factors and treatments like minoxidil and finasteride can help, but more research and better public awareness are needed.

Hair follicles may soon be used more for targeted and systemic drug delivery.

Hair growth is influenced by hormones and goes through different phases; androgens can both promote and inhibit hair growth depending on the body area.

Human hair follicles can grow and stay healthy for up to 8 days in a lab setting.

Intralesional triamcinolone injections can effectively stop frontal fibrosing alopecia with minimal side effects.

Hair ages due to genetics and environmental factors, leading to graying and thinning, with treatments available for some conditions.

AGA causes hair loss by shrinking hair follicles due to DHT binding, and can be treated with finasteride and minoxidil.

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

The telogen phase of hair growth is active and important for preparing hair follicles for regeneration, not just a resting stage.

Male pattern baldness may be caused by factors like poor blood circulation, scalp tension, stress, and hormonal imbalances, but the exact causes are still unclear.
