March 2009
TLDR Low-temperature extracts of black beans, peony, and green tea improve scalp health and are better than traditional hot-water extracts.
The 2009 study investigated the use of low-temperature extraction of black beans, peony, and green tea, known for their scalp improvement properties. The study found that this method retained over twice the antioxidant strength compared to hot-water extraction. The low-temperature extracts were found to effectively strengthen hair follicles, moisturize the scalp, and prevent itchiness. Therefore, the study concluded that low-temperature extracted black beans, peony, and green tea could be used effectively in scalp treatments.
