Hair grays due to oxidative stress and fewer functioning melanocytes.

Laser treatment increases hair density and thickness safely in women with hair loss.

Hair growth slows and shedding increases after childbirth, but most women don't experience excessive hair loss.

Certain signals are important for reducing specific chemical markers on hair follicle stem cells during rest periods, which is necessary for healthy hair growth.

Researchers found that bulge cells from human hair can grow quickly in culture and have properties of hair follicle stem cells, which could be useful for skin treatments.

EPR spectroscopy showed that spontaneous hair growth results in thicker skin and less pigmented hair than depilation-induced growth.

Over 50% of women over 50 experience hair loss, with minoxidil being the only proven effective treatment.

Best hair transplant results happen when tissues are least damaged.

Experienced hair transplant surgeons suggest a limited number of hair follicles can be used for transplants, and recommend conservative methods to avoid scarring and depletion.

Effective repair of bad hair transplants requires skilled techniques and careful use of donor hair, with strategies like reimplantation and camouflage, and new methods to minimize scarring.

Hair transplantation techniques have improved over 12 years, with follicular unit grafting providing more natural results and potential future advances in automation and genetics.
