Fine-tuning stem cell metabolism prevents hair loss

A team of researchers from Cologne and Helsinki has discovered a mechanism that prevents hair loss: hair follicle stem cells, essential for hair to regrow, can prolong their life by switching their metabolic state in response ...

Researchers identify microRNA that shows promise for hair regrowth

Researchers from North Carolina State University have identified a microRNA (miRNA) that could promote hair regeneration. This miRNA—miR-218-5p—plays an important role in regulating the pathway involved in follicle regeneration, ...

The real reason behind goosebumps

If you've ever wondered why we get goosebumps, you're in good company—so did Charles Darwin, who mused about them in his writings on evolution. Goosebumps might protect animals with thick fur from the cold, but we humans ...

Hair growth finding could make baldness 'optional'

The best way to avoid baldness is to stop hair from falling out in the first place. Now, researchers say a new hair growth discovery might help men keep their locks for a lifetime.
