January 2020 in “Journal of Pharmacognosy and Phytochemistry” This study observed that a polyherbal hair oil made from virgin coconut oil and extracts of nine different herbs demonstrated effectiveness in promoting hair growth with a cooling effect and no reported side effects, based on various evaluated properties.
In this study, researchers developed a standardized Ayurvedic hair pack using natural ingredients like Shikakai and Amla and confirmed its safety and pH suitability; they concluded it could be a scientifically validated alternative to synthetic hair products.
April 2024 in “Research Square (Research Square)” This study found that bioconjugating 16-methylheptadecanoic acid (16-MHA) to damaged hair can mimic the protective properties of 18-methyleicosanoic acid (18-MEA), restoring the hair's structural integrity and moisture homeostasis, even after washing.
March 2024 in “Journal of Society of Cosmetic Chemists of Japan” In this study, a medicated hair growth tonic containing RJ extract increased hair counts, the proportion of anagen phase hairs, and scalp moisture in human trials, although the specific role of RJ in hair growth remains unclear due to other active ingredients.
This study developed a hat-shaped device with wearable sensors to estimate scalp moisture content using machine learning, demonstrating that it can provide accurate measurements comparable to professional scalp analyzers without the need for high-cost equipment.
