tDCS brain stimulation for depression
Developed by neuroscientists and clinicians. Used by the NHS.
Depression changes how your brain works. Flow helps change it back.
Depression is not just a chemical imbalance, it is a shift in how your brain functions.
Flow uses transcranial direct current stimulation (tDCS), a gentle electrical stimulation to target the part of the brain linked to mood.
A non-invasive, drug-free treatment. Flow targets the part of the brain linked to mood regulation.
Unlike medication, Flow works by stimulating the brain externally. No invasive procedures. No sexual side effects, no weight gain, no sedation.
Flow encourages neurons to fire more regularly by delivering a low-level current to the Dorsolateral Prefrontal Cortex.
Flow's regular stimulation gradually re-exercises the underactive neural pathways linked to depression in the Dorsolateral Prefrontal Cortex (DLPFC), a process called neuroplasticity.
Over time, your brain rebuilds the healthy patterns it needs.
Safety
The Flow headset has been designed and extensively tested by experts.
It is CE-certified and complies with all European and UK laws for medical devices. It has also received approval from the Food and Drug Administration (FDA) for at-home depression treatment in the United States.
The technology Flow uses (tDCS) has been used in clinical settings for decades, and its safety and performance has been evaluated in hundreds of clinical trials. To learn more about the safety and performance of Flow in these clinical trials, visit our Research page.
It is important to always use Flow in accordance with the user manual.

No serious side effects
Your safety is our priority
In over two decades of research on tDCS, no serious side effects have been reported.
Fewer than 5% of Flow users have reported side effects1. The most common are skin reactions, headaches, tiredness, or temporary changes in mood. Most resolve within hours to a few days, and tend to lessen the more you use it.
Safety and PrecautionsHow Flow Compares to Other Treatments
Many people use Flow on its own or alongside other treatments. Here's how it compares to antidepressants and TMS:
| Feature | tDCS | Antidepressants | TMS |
|---|---|---|---|
| Side effects | Minimal(tingling, skin irritation) | Mild to severeSexual dysfunction (up to 80% of users), weight gain, insomnia. | Mild to moderate(e.g. headache) |
| Non-invasive | Yes | No | Yes |
| Drug-free | Yes | No | Yes(can be used in clinic) |
| Typical use | At-hometypically 3x/week | 1 pill a day for 6-12 monthsDosage/drug can differ by prescription | Clinic sessions5×/week |
| Time to benefit | Weeks(often after 2–3 weeks) | Months2-3 months typically | Weeks(often after 2–4 weeks) |
| Can be combined with other treatments? | YesRemission rates increase 18% when antidepressant users add Flow2 | YesMust be supervised by a doctor | YesOften combined with medication |
