A genomic study of baldness identified more than 200 genetic regions involved in this common but potentially embarrassing condition. These genetic variants could be used to predict a man's chance of severe hair loss.
Does how much hair a man has matter in how he is perceived? The answer is yes, according to a new article, and this reality can play a role in workplace and social success, say the authors of a new report.
In a review of 19 studies, researchers say they can confirm a 'strong association' between certain scalp-pulling hairstyles -- many common among African-Americans -- and the development of traction alopecia, gradual hair loss caused by damage to the hair follicle from prolonged or repeated tension on the hair root.
African-American women are prone to hair loss, and new data illustrates the scope of this problem, which often goes undiagnosed. Women who are concerned about losing their hair should consider changing their styling practices and see a dermatologist if they notice any signs of hair loss.
Stem cells residing in hair follicles are held in an inactive state for long periods of time. A new study shows that these quiescent periods are essential for maintaining the cells' rejuvenating activity over time, and clarifies the mechanisms that bring the cells in and out of quiescence.
Hair analysis has become standard practice for determining whether someone has abused illicit drugs. But some experts have questioned whether current methods to wash away external contaminants from samples might affect test results. Now one team confirms that for cocaine detection, a pretreatment step can cause the drug on the outside of a hair shaft […]
The first gene identified for greying hair has been discovered by an international study, confirming greying has a genetic component and is not just environmental. The study analyzed a population of over 6,000 people with varied ancestry across Latin America to identify new genes associated with hair color, greying, density and shape, i.e. straight or […]
Why people lose their locks in old age may be related to the aging of hair follicle stem cells, two new studies suggest. Though it is known that mammals that live for longer lifespans lose their hair, the mechanisms underlying this fate have been a mystery.
