Researchers have shown that serotonin directly stimulates dermal papilla cells and promotes hair growth in lab-grown hair ...

Rather, the stress hormone prevented dermal papilla cells from secreting Gas6, a molecule that the researchers showed can activate the hair follicle stem cells,” reads the release.

Does stress really make your hair turn gray? Trichologists explain the connection between increased stress levels and early gray hair.

This finding also provides clues to the type of signals that follicle stem cells may send to dermal papilla. What's more, BMP6 specifically maintains the molecular identity of dermal papilla cells.

In the study, the researchers obtained cells called dermal papilla cells, which give rise to hair follicles, from seven people with pattern baldness.

Hair growth finding could make baldness 'optional' "The future of hair loss looks very promising and this study shows that baldness may soon be optional," said Dr. Michele Green.

Throughout recorded history, our hair and nails have played an important role in signifying who we are and our social status. You could say they separate the caveman from the businessman.

Have you ever noticed your hair thinning during particularly stressful times? You're not alone. Stress has long been suspected as a contributor to hair loss, but a groundbreaking study offers new ...
