Nerve signals are crucial for hair follicle stem cells to become skin stem cells and help in wound healing.

The document concludes that the hair cycle is a complex process involving growth, regression, and rest phases, regulated by various molecular signals.

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

Lactate production is important for activating hair growth stem cells.

Hair follicle stem cells are key for hair and skin regeneration, can be reprogrammed, and have potential therapeutic uses, but also carry a risk of cancer.

The dermal papilla is crucial for hair growth and health, and understanding it could lead to new hair loss treatments.

Too much Smad7 changes skin and hair development by breaking down a protein called β-catenin, leading to more oil glands and fewer hair follicles.

The document concludes that understanding hair structure is key to diagnosing hair abnormalities and recommends gentle hair care for management.

Hair follicles produce and respond to melatonin, affecting hair growth and sensitivity to estrogen.

Hormones, especially androgens, play a big role in acne, but most acne sufferers don't have a hormone disorder. Hormonal treatments, including birth control pills, can be very effective for women whose acne doesn't improve with regular treatments.

Finasteride and minoxidil are effective for hair regrowth, while treatments for alopecia areata have varying success and continuous treatment is necessary.

Manipulating the catagen and telogen phases of hair growth could lead to treatments for hair disorders.

We need more research to better understand human hair follicle stem cells for improved treatments for hair loss and skin cancer.

MicroRNA-214 is important for skin and hair growth because it affects the Wnt pathway.

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

The document concludes that the hair cycle is a complex process involving growth, regression, and rest phases, regulated by various molecular signals.

There are many treatments for permanent hair loss disorders, but their effectiveness varies and there's no clear best option.

No treatment fully prevents hair loss from chemotherapy yet.

Grafted rodent and human cells can regenerate hair follicles, but efficiency decreases with age.

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

Follistatin helps hair growth and cycling, while activin prevents it.

EVAL membranes help create cell structures that can regrow hair follicles.

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

Male hormones are important for hair and oil gland development and can cause conditions like excessive hair growth and acne.

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.

Minoxidil and finasteride treat hair loss; more research needed for other options.

Blocking BMP signaling causes hair loss and disrupts hair growth cycles.

Hair growth is influenced by interactions between skin layers, growth factors, and hormones, but the exact mechanisms are not fully understood.

Activating Nrf2 protects human hair follicles from oxidative stress and helps prevent hair growth inhibition.

Children's hair grows in different types from before birth through puberty, with growth rates and characteristics varying by age, sex, and race.
