As people age, their hair follicles produce less pigment, leading to gray and white hair, due to factors like reduced enzyme activity and damage to melanocyte DNA.

Chronic Telogen Effluvium may resolve after years and is diagnosed by examining the patient's history and clinical signs, with treatment aimed at underlying causes and possibly minoxidil.

Hair loss reduces hair thickness and coverage, but drug treatments mainly revive dormant hairs rather than reverse thinning; patients often undervalue their hair loss severity.

The substances improved hair regrowth and protected hair cells in humans and mice.

Men with early balding showed higher levels of certain genes linked to hair loss and possibly prostate cancer.

DHT, a testosterone byproduct, causes male pattern baldness.

Alopecia areata is a chronic condition causing hair loss, with new treatments targeting the immune system showing promise.

Hair loss, known as Androgenetic Alopecia, is often caused by hormones and can be diagnosed using noninvasive techniques. Treatments include topical minoxidil and oral finasteride, with new treatments being explored. There may also be a link between this type of hair loss and heart disease risk.

Multi-omics techniques help understand the molecular causes of androgenetic alopecia.

Cooling hair micrografts during transplantation does not improve their survival or growth.
