Caffeine doesn't just make Mondays more bearable. Scientists have recently uncovered another possible benefit: It might help bulk up thinning hair by promoting hair growth. The catch? Unfortunately, just sipping a latte isn't going to cut it.
Here's what you need to know: When scientists treated weakened hair follicles with a caffeine solution, the speed of hair growth increased by up to 25 percent, says Tobias U. Fischer, a dermatologist at the University of Lübeck in Germany. Caffeine activates a growth factor that helps prevent hair cells from dying or going into a dormant state, he explains.
Sadly, just drinking coffee—or even applying it to your head in an experimental DIY mask—won't do anything for your hair. It takes a special treatment with the optimal formulation (such as Plantur 39 Caffeine Treatment for women), which is currently available in Europe. Here's hoping it arrives stateside soon. We're guessing it might be as popular as Starbucks.
