A research team from South Korea and Hong Kong has created a new phototherapy system against alopecia. Their proposal is a flexible device, similar to a fabric, that integrates into a common hat. This development replaces rigid LED helmets with a more discreet and uniform application solution, using organic light-emitting diodes.
Infrared OLED Technology to Activate Follicles 🔴
The system uses OLEDs that emit near-infrared light (730-740 nm) homogeneously over the scalp. This wavelength is designed to act on the dermal papilla cells, which regulate hair growth. In tests with cell cultures, it reduced aging markers by 92% compared to untreated cells, surpassing conventional red light. The results were published in Nature Communications.
The Future is Wearing a Hat and Having Your Hair Grow 💡
The evolution of hair treatments seems clear: from lotions and transplants, we move to science fiction helmets and now to the era of therapeutic fashion accessories. Soon, choosing a hat will not be a matter of style, but of desired hair density. One more step for the phrase wearing something on your head to have a literally deeper meaning.
