SCD1 is important for hair growth by keeping the connection in skin cells where hair stem cells live stable.

Aging changes sugar molecules on skin stem cells, which may affect their ability to repair skin.

BMI1 is essential for preventing hair greying and maintaining hair color.

Human hair follicle stem cells can turn into multiple cell types but lose some of this ability after being grown in the lab for a long time.

Dermal papillae cells, important for hair growth, come from multiple cell lines and can be formed by skin cells, regardless of their origin or hair cycle phase. These cells rarely divide, but their ability to shape tissue may contribute to their efficiency in inducing hair growth.

Androgens affect bone and fat cell development differently based on the cells' embryonic origin.

The study mapped yak skin cells to understand hair growth better.

The article concludes that creating a detailed map of normal human skin at the single-cell level is important.

Treg cell-based therapies might help treat hair loss from alopecia areata, but more research is needed to confirm safety and effectiveness.

LED light helps hair follicle cells grow and prevents them from dying by activating certain cell pathways.

Stem cell treatments show promise for hair loss but need more research.

Exosomes from skin cells can boost hair growth by stimulating a gene called LEF1.

Wool follicles are complex, involving interactions between different cell types and structures.

Decorin helps hair growth by influencing specific cell signals.

Autophagy helps activate hair stem cells and hair growth by changing their energy use to glycolysis.

GFP transgenic mice help study cell origins in skin grafts.

Artemis protein may help control hair growth and health by influencing cell processes.

Extracts from three Polynesian plants were found to promote hair growth by affecting cell growth and gene expression related to hair.

Androgen receptor activity blocks Wnt/β-catenin signaling, affecting hair growth and skin cell balance.

Progranulin overexpression leads to shorter, thinner hair and increased cell death in mouse hair follicles.

The arrector pili muscle might play a role in hair loss and needs more research to understand its impact.

Human hair follicle stem cells show signs of low oxygen levels, which may be important for hair growth and preventing baldness.

Miniaturized hairs stay connected to muscle in alopecia areata, allowing possible regrowth, but not in androgenetic alopecia.

Trichoscopy helped diagnose and treat a woman with two different types of hair loss.

Regulating cell death in hair follicles can help prevent hair loss and promote hair growth.

Eyelashes are important for looks and eye protection, and more people are treating sparse eyelashes; more research is needed to understand eyelash biology and improve treatments.

Researchers discovered potential origins and new treatments for skin cancer, including biomarkers for melanoma and therapies that reduce tumor growth.

Microspheres about 1.5 micrometers in size can best penetrate hair follicles, potentially reaching important stem cells.

Nanoparticles improve drug delivery through the skin but more research is needed on their long-term effects and skin penetration challenges.

Hair follicles are hormone-sensitive and involved in growth and other functions, with potential for new treatments, but more research is needed.
