Men's thigh hair grows longer and has a longer growth cycle than women's, but arm hair growth is similar between genders.

Inactive hair follicle stem cells help prevent skin cancer.

Notch signaling is essential for healthy skin and hair follicle maintenance.

Zinc can both inhibit and stimulate mouse hair growth, and might help recover hair after chemotherapy.

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

Scarring alopecia affects different hair follicle stem cells than nonscarring alopecia, and the infundibular region could be a new treatment target.

The document explains hair growth and shedding, factors affecting it, and methods to evaluate hair loss, emphasizing the importance of skin biopsy for diagnosis.

Stem cells, especially from fat tissue and Wharton's jelly, can potentially regenerate hair follicles and treat hair loss, but more research is needed to perfect the treatment.

Hair growth is influenced by various body and external factors, and neighboring hairs communicate to synchronize regeneration.

Hair loss in males involves inflammation, collagen buildup, and follicle damage, with severity increasing with age and baldness duration.

The conclusion is that we need more effective hair loss treatments than the current ones, and these could include new drugs, gene and stem cell therapy, hormones, and scalp cooling, but they all need thorough safety testing.

Some hair loss disorders are caused by genetic mutations affecting hair growth.

MicroRNAs play a crucial role in skin and hair health, affecting everything from growth to aging, and could potentially be used in treating skin diseases.

Healthy women tend to lose more hair in July and April, and the least in February.

Skin and hair can regenerate after injury due to changes in gene activity, with potential links to how cancer spreads. Future research should focus on how new hair follicles form and the processes that trigger their creation.

Mice are useful for researching human hair loss and testing treatments, despite some differences between species.

sPLA2-X is crucial for normal hair growth and follicle health.

Mice without collagen VI have slower hair growth normally but faster regrowth after injury.

Polyamines are important for hair growth, but more research is needed to understand their functions and treatment potential.

Plet-1 protein helps hair follicle cells move and stick to tissues.

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

Pulsed-intense light can significantly reduce hair, with effectiveness depending on treatment number and timing, and has mild side effects.

Immune cells around hair follicles help control hair growth and could be targets for treating hair disorders.

Graying hair happens due to aging and might be delayed by new treatments.

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

Increasing Wnt5a in mice skin delays hair growth but doesn't stop it.

Intu gene is crucial for hair follicle formation by helping keratinocytes differentiate through primary cilia.

Understanding hair biology is key to developing better treatments for hair and scalp issues.

Researchers created a lab model to study human hair growth, showing it can grow and self-regulate outside the body.

Hair follicle studies suggest that maintaining telomere length could help treat hair loss and graying, but it's uncertain if mouse results apply to humans.
