Yes, Halo uses transcranial direct current stimulation (tDCS), a well-researched method with a strong safety record. It delivers a gentle electrical current (2mA) to the left dorsolateral prefrontal cortex (DLPFC), a key region of the brain involved in mood regulation.
Our commitment to safety is built on three key pillars:
- Grounded in clinical research: tDCS has been used in clinical and academic settings for decades. Hundreds of clinical trials have confirmed its safety and effectiveness when used as directed.
- Gentle and non-invasive: Halo works by gently stimulating your brain’s neural pathways from the outside of your head. Most users report only a mild tingling or warmth on their skin under the headset pads.
- A trusted safety profile: The exact technology in Halo has been used by over 50,000 people. No serious side effects have been reported.
