Skin and hair renewal is maintained by both fast and slow cycling stem cells, with hair regrowth primarily driven by specific stem cells in the hair follicle bulge. These cells can also help heal wounds and potentially treat hair loss.

Scientists successfully created fully functional hair follicles using bioengineering methods and stem cells.

Melatonin helps Cashmere goats grow more hair by affecting certain genes and cell pathways.

Hair loss in men (androgenetic alopecia) is significantly linked to decreased scalp sensitivity, but not temperature sensitivity. More research is needed to confirm this. Comparing this hair loss to leprosy is unsupported and stigmatizing.

Stem cell therapy is more effective than minoxidil for hair growth in androgenic alopecia.

Long-term use of certain prostate drugs can worsen erectile dysfunction by changing penile tissue, especially in rats with high blood pressure.

Researchers created hair-inducing human cell clusters using a 3D culture method.

The document concludes that the skin is a complex organ providing protection, sensation, and healing, with challenges in treating conditions like itchiness.

RNA can be extracted from horsehair roots for analysis.

Melatonin helps Cashmere goat hair follicles grow by affecting stem cell signals and the surrounding microenvironment.

Adult skin cells can be used to create new hair in a lab.

P144® improves hypertrophic scars by reducing size and thickness and increasing elasticity.

Nude mice with grafted human skin developed scars similar to human hypertrophic scars.

Freezing and storing special stem cells from hair follicles keeps their ability to grow hair and turn into different cell types.

EVG staining is a valuable, simple, and cost-effective method for diagnosing various skin conditions in dermatopathology.

Melatonin helps Cashmere goats grow more hair by affecting genes and cell signals important for hair and blood vessel development.

Potassium channel openers help form elastic fibers in arteries and can treat elastin deficiency and hypertension.
