Mesenchymal stem cells show potential for skin healing and anti-aging, but more research is needed for safe use, especially regarding stem cells from induced pluripotent sources.

Hair follicle cells age faster and lose pigment due to less catalase, causing hair to turn gray.

Melatonin, a hormone, can help protect skin from aging by reducing stress, inflammation, and damage, and may also help treat hair loss in women.

People with alopecia areata have higher levels of a heart disease marker than those without hair loss.

Eating barley for life may lead to healthier aging in mice.
