Red and infrared light therapy improves hair growth in balding patients.

A 73-year-old man's grey-white hair turned dark brown after eczema treatment.

Understanding skin structure and development helps diagnose and treat skin disorders.

This article describes a protocol for using bioengineered techniques to regenerate functional hair follicles and their stem cell niches by manipulating epithelial and mesenchymal cells.

This review discusses the reuse of molecular mechanisms involved in embryonic skin development for maintaining adult epidermal homeostasis and reports no new results.

This study found that K17 is crucial for the structural integrity and survival of hair-producing cells, with K17 null mice developing alopecia due to hair fragility and follicular alterations.

This article reviews the similarities in early development processes of hair follicles, teeth, and mammary glands and reports no new experimental findings.

This study found that red ginseng oil may enhance hair growth and protect skin from UV damage in mouse models by promoting regenerative processes and reducing inflammation.

This study shows that BMP2 and BMP7 play complex, necessary roles in feather development by regulating dermal condensation formation, with BMP7 acting early as a chemoattractant and BMP2 halting cell migration.

This study found that mice with a specific loss of DNA methyltransferase 1 showed uneven epidermal thickness, reduced hair regeneration, and progressive alopecia, emphasizing DNA methylation's role in stem cell homeostasis.
