Frequently asked questions
What is Halo and how does it work?
Halo is a brain stimulation wearable that uses transcranial direct current stimulation (tDCS) to help:

It delivers gentle, low-intensity electrical currents to the prefrontal cortex, a region of the brain involved in cognitive and emotional processes.
Is Halo safe to use?
Halo uses transcranial direct current stimulation (tDCS) - a non-invasive, low-intensity technology that has been evaluated in over 100 peer-reviewed clinical studies.
Originally developed for use in medical and research settings, tDCS technology has a strong safety profile and has been used for over two decades.
Some users may experience mild tingling or skin redness during or after use.
