Children with atopic dermatitis often have sleep problems due to itching and may benefit from melatonin, which helps with sleep and skin symptoms.

Researchers found a genetic link for hereditary hair loss but need more analysis to identify the exact gene.

Elastic Net DNA methylation clocks are inaccurate for predicting age and health status; a "noise barometer" may better indicate aging and disease.

The nervous system helps control stem cell behavior and immune responses, affecting tissue repair and maintenance.

Fine wool sheep have more genes for wool quality, while coarse wool sheep have more for skin and muscle traits.

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.

Coffee bean residue extract helps hair growth by activating cell processes.

FGF9 helps hair follicles grow in small-tailed Han sheep by affecting cell growth and certain signaling pathways.

Finasteride treatment in rats changed the expression of genes related to psychiatric and neurological functions, and these changes persisted after stopping the drug.

Melatonin affects many body functions beyond sleep by interacting with specific receptors in various tissues.

Curcumin may help reverse aging by targeting specific genes.

Vav2 changes how hair follicle stem cells' genes work as they age, which might improve regeneration but also raise cancer risk.

Thyroid problems can cause hair loss and change hair texture.

Stress can worsen skin conditions and stop hair growth by affecting the body's stress response system.

Deleting the PTEN gene in mice causes nerve cells to grow larger and heal better after injury, but may cause overgrowth and hair loss in older mice.

Certain genetic markers linked to reproductive potential were identified by their impact on a protein's ability to bind to genes.

Dexamethasone affects hair growth by altering levels of proteins that either promote or inhibit hair follicle growth.

Skin stem cells are maintained by signals from nearby cells and vary in their ability to renew and mature.

Prolactin may affect hair growth differently based on gender and scalp area.

Working night shifts for four days can lower the body's ability to use insulin, which may increase the risk of type 2 diabetes.

CRISPR/Cas9 has improved precision and control but still faces clinical challenges.

Hair growth and health are influenced by stress and hormones.

New treatments are needed for PCOS that target its genetic, hormonal, and metabolic causes.

Light can turn on hair growth cells through a nerve path starting in the eyes.

Stem cell self-renewal is complex and needs more research for full understanding.

Hormones and neuroendocrine factors control hair growth and color, and more research could lead to new hair treatment options.

Mutations in the NR3C1 gene cause a rare condition that affects hormone signaling and can lead to various symptoms, with dexamethasone as a treatment option.

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

Brain-Derived Neurotrophic Factor (BDNF) slows down hair growth and promotes hair follicle regression.

Maintaining DNA integrity in stem cells is crucial to prevent aging and cancer.
