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

Discover the difference between hair loss and shedding, including causes, signs, and treatment options to maintain healthy hair growth.

Now, a gene mapping study on human scalp hair whorls —a patch of hair growing in a circular pattern around a single point that is determined by the orientation of hair follicles—shows that ...

Humans evolved in Equatorial Africa—where the sun is often overhead throughout the year, meaning the scalp receives more levels of solar radiation.

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 ...

Naturally curly hair is an almost uniquely human trait. Now we might know why.

In short, human ancestors may have always had the ability to grow long scalp hair, but the trait remained dormant until certain environmental and biological conditions — like walking upright on ...

The human scalp contains approximately 100,000 hair follicles, each following its own growth cycle. This natural cycle consists of three distinct phases: ...

Life before air conditioning: Curly hair kept early humans cool Tightly curled scalp hair protected early humans from the sun's radiative heat, allowing their brains to grow to sizes comparable to ...
