In 2023, the market for home neurofeedback systems has experienced an unprecedented boom thanks to the latest advancements in the industry. Over the past five years, a fresh wave of headbands and smartphone devices designed for direct-to-consumer use have been introduced. While this surge in options is a positive development, it also presents challenges. The lack of regulatory oversight for the term "neurofeedback" has resulted in a broad range of products with varying capabilities and purported benefits being marketed under that label. These systems run the gamut from professional EEG-based equipment adapted for home use to low-cost headbands that require minimal computing power, and prices can vary widely from a few hundred to tens of thousands of dollars. Given this maze of options, it can be difficult for consumers to sort through the information. This article aims to clarify the distinctions between different systems, the scientific principles behind them, and the expected outcomes.
