A centuries-old Chinese medicinal root is drawing fresh scientific attention for its potential role in hair regrowth. A new research review suggests the plant, long used in traditional medicine, may affect several biological processes involved in common hair loss. The findings focus on androgenetic alopecia, the most widespread form of thinning hair.
Unlike many existing treatments that target a single pathway, the root appears to act on multiple fronts. Research indicates it may reduce the effects of hormones linked to follicle shrinkage, protect hair follicle cells from damage, activate natural growth signals, and improve blood flow in the scalp. Together, these actions may support healthier hair cycling rather than simply slowing loss.
The review also highlights alignment between historical medical texts and modern biological findings. While the results suggest potential for regrowth, researchers emphasize that further high-quality clinical trials are needed to confirm effectiveness and safety. The work underscores how studying traditional remedies may offer new insights into long-standing medical challenges.
