Here's a video with instructions on how to turn your Capillus cap, and some of the differences in turning off the battery pack, depending on the model.
Note: Newer models turn off automatically after 6 minutes.
The Capillus laser therapy cap is powered by a rechargeable lithium-ion battery pack. The battery pack is lightweight and easily slips into your pocket, or you can use it with the convenient battery clip and attach it to your belt or waistband.
The video and information below applies to earlier models of the Capillus cap.
Place the laser dome on your head and simply TAP (do not "hold") the power button to begin treatment.
