How Halo Works
Created by neuroscientists & endorsed by doctors
Your brain runs on electrical activity. Every thought, emotion, and night of sleep depends on precise patterns of communication between billions of neurons. Halo works with this natural electrical language - helping you feel and function at your best.
Halo applies this research to everyday wellness - making the benefits of tDCS accessible in a safe, simple headset for home use.

The prefrontal cortex
Your brain’s control center
Halo targets the dorsolateral prefrontal cortex (DLPFC) - a key region involved in mood regulation, sleep quality, focus, and motivation.
When this area is functioning optimally, it helps you:
- Maintain a balanced and positive mood
- Fall asleep more easily and wake up rested
- Stay focused and mentally clear throughout the day
By gently stimulating this region, Halo helps support healthy brain activity patterns linked to better mood, sleep, and focus.
Most users describe a light tingling sensation during the first few minutes of a session, which fades quickly.
Real world improvements
After 4 weeks with Halo
In an analysis of Halo users, significant improvements were seen in mood, sleep, and focus after just two weeks of regular use.
By four weeks, around 70% of users reported improvement across all three outcomes, with gains continuing to strengthen through week six.*
Mood
+73%
Sleep

Use for 30 minutes, 5x for 3 weeks followed by 2x per week ongoing. Use while reading, relaxing, or getting ready for the day.
No serious side effects
Your safety is our priority
In over two decades of research on tDCS (the technology Halo uses), no serious side effects have been reported across hundreds of research studies.
Halo uses the same gentle, low-level stimulation to support brain wellness.
Most users experience only mild, temporary side effects. These are generally well-tolerated, with most users reporting the sensations become milder over time. You may also experience some skin irritation, such as redness or itchiness, which is common and temporary. Other users may notice tiredness, headaches, tinnitus (which is rare).
Built on the same tech as Flow Neuroscience, based on decades of tDCS research and trusted by 50,000+ users
Benefits that re-enforce over time
Your brain adapts with consistent use. Many users notice benefits within 2–4 weeks, with continued improvements over time. Using Halo regularly helps you maintain a balanced mood, deeper sleep, and sharper focus as part of your ongoing wellness routine.
Phase 1: Activation
5 sessions per week for 3 weeks. Establishes the foundation – supporting areas of the brain linked to mood, sleep, and focus.
Phase 2: Optimization
2 sessions per week ongoing. Maintains and strengthens results - for long-term improvements.

Feel the change
Each session strengthens the neural pathways that support mood, sleep, and focus. Over time, these subtle shifts add up - helping you feel more steady, clear, and in control day to day.

FAQs
Is Halo the same as ECT?
No. Electroconvulsive therapy (ECT) is a hospital-based procedure used for medical treatment under anesthesia. Halo uses a completely different approach called transcranial direct current stimulation (tDCS) - a gentle, low-level current that’s about 400 times weaker than ECT.
tDCS works by softly modulating the brain’s natural electrical activity, supporting healthy patterns linked to better mood, sleep, and focus. Halo delivers this safely and comfortably through a wearable headset designed for everyday wellness use.
Can I use Halo at home?
Yes. Halo is designed for safe, easy home use. The headset connects via Bluetooth to the Halo app, which guides each session and tracks your progress.
tDCS has traditionally been available only in research and clinical settings - Halo brings the same technology into a wellness-focused, user-friendly device for healthy adults.
Does Halo involve taking medication?
No. Halo is a completely non-invasive, drug-free way to support brain wellness. It works naturally with your brain’s own electrical activity, helping you feel more balanced, focused, and well-rested - without any chemicals or medication.
Is tDCS a form of neuromodulation?
Yes. tDCS (transcranial direct current stimulation) is a gentle form of neuromodulation - a way of influencing brain activity through safe, low-level electrical currents. Halo uses this method to help support the brain networks involved in mood, sleep, and focus.
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.
