The science behind the Samphire Headband.

Here is how it works.

The Samphire Headband works by using a low electrical current to stimulate certain parts of the brain. It's kind of like giving your brain a (deeply scientific, and highly researched) relaxing massage. It’s been around for a while - just not for women.

They were right. It is all in your head.

Your brain can change across the menstrual cycle’s four phases. During the luteal phase, many menstrual symptoms can be linked to observable brain changes in the prefrontal cortex.

Pain sensitivity is often higher in the luteal and menstrual phases.

Pain sensitivity is regulated by structures deep within the brain. These can be indirectly targeted by stimulating the motor cortex, helping reduce pain sensitivity.

“PMS” covers more than 100 possible symptoms.

Premenstrual syndrome (PMS), Premenstrual dysphoric disorder (PMDD), and dysmenorrhea are associated with various symptoms experienced during the premenstrual phase. These symptoms are often collectively referred to as PMS, though this term lacks precise research and terminology.

Tested against the toughest symptoms.

The Samphire Headband utilises transcranial direct current stimulation (tDCS). For decades, tDCS has been used to manage chronic pain, and as a treatment option for depression in clinical and research settings.

Safe and tested clinical parameters

The Headband adopts a stimulation profile that has been tested across more than a million minutes of stimulation worldwide, optimising for safety and efficacy.

Gently restores and balances brain connections.

The Headband stimulates neural nodes within brain networks using low electric currents. This helps restore balanced brain connectivity, which can be disrupted during the premenstrual period, causing symptoms.

Reduction in pain sensitivity through the motor cortex

A temporary reduction of pain sensitivity is achieved through the stimulation of networks in the motor cortex.

Backed by science. Rooted in research.

We don’t just closely follow, but also lead on crucial research, staying at the forefront of innovation. The Samphire Headband’s underlying neurotechnology has been tested and approved by leading scientists for over three decades.

Every day we learn more about neurotechnology and women's health. Continuous research sheds light on the most optimal mechanisms and parameters, as well as the underlying neurobiology of women.
