Safe and Well Tolerated

Your safety is our priority. 

tDCS - the same gentle brain stimulation technology used in Halo has been studied for more than two decades with an excellent safety record. Across extensive research and real-world use, no serious side effects have been reported.

Halo sessions are generally very well tolerated. In some cases, mild and temporary effects such as slight redness or tingling under the pads may occur. These typically fade on their own shortly after the session.

What is Halo and how does it work?

Halo is a brain stimulation wearable that uses transcranial direct current stimulation (tDCS) to help:

  • Enhance mood
  • Improve focus, creativity, learning speed, and problem solving
  • Support better sleep quality and duration

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.

When will it ship?

Orders placed before 12pm PT (Pacific Time) on business days ship the same day, otherwise they'll ship the next business day. Delivery generally takes 2–5 business days depending on your state. Free shipping for all headset orders.

Holiday Shipping Notice: Please note that delivery times may be longer than usual due to the busy holiday period. We appreciate your patience and recommend ordering early to ensure your delivery arrives on time.

What does it feel like?

Most users feel a mild tingling or warming sensation under the electrodes at the start of a session. This usually fades within 10 minutes. Sessions are generally painless and non-invasive.

Do I need the app to use Halo?

Yes - the Halo app is required to operate the headset. It connects via Bluetooth, guides each session, and tracks your usage over time.

The app is free to use and available on iOS and Android.

To run a session, you’ll also need Halo stimulation pads. One box is included with your headset. After that, pads are available for purchase through the Halo website.

Who is Halo for?

Halo is designed for high-performers, creatives, biohackers, and wellness seekers looking to elevate their mood, sleep and focus.

How often should I use it?

For best results, we recommend sticking to the session schedule - by using Halo 5 times per week for the first 3 weeks, followed by 3 sessions per week. Each session takes 30 minutes. Benefits build with consistency - just like physical training.

Do you ship internationally

No - at this time, Halo is only available for shipment within the United States. We’re working to expand availability in the future. Sign up for updates if you’d like to be notified when we launch in other countries.
