Researchers have found that combining scalp cooling treatment with antioxidants can significantly reduce or even prevent the ...

Each of the approximately 100,000 follicles on the human scalp operates independently, cycling through three distinct phases: anagen (active growth), catagen (transitional phase), and telogen ...

The first gene mapping study on human scalp hair whorls not only shows that hair whorl direction has a genetic basis, but also that it is affected by multiple genes. Four associated genetic ...

Humans are a bit weird, all things considered. We’re bipedal, which is already pretty strange; our brains and heads are outsized to a degree that literally causes us pain; and to top it all off ...
