Just late this year, another one of the biggest steps in stem cell research reignited hope among hair loss sufferers. Yale researchers discovered molecular signals that could command the hair follicles to begin the hair generation cycle. The researchers expressed that these findings paved the way for new possible designs of hair loss treatments.

According to the lead author of the paper, Valerie Horsley, ‘If we can get these fat cells in the skin to talk to the dormant stem cells at the base of hair follicles, we might be able to get hair to grow again’. While it is true that roots of balding-prone hair follicles have stem cells in them, these stem cells lose the ability to spur hair growth because they lack the signals from within the skin to make them capable of hair generation, unlike those stem cells under investigation.
