Babchi (Psoralea corylifolia) has a long history of use in traditional Ayurvedic and Chinese medicine for a variety of skin conditions, most notably vitiligo, due to its active compound psoralen. Its use for supporting hair health, particularly in cases of hair loss or thinning, is primarily rooted in traditional practices rather than robust scientific validation. In Ayurveda, Babchi oil is sometimes applied topically or used in formulations aimed at stimulating hair growth and addressing scalp disorders. The rationale is often tied to its purported abilities to improve blood circulation, stimulate hair follicles, and address underlying scalp conditions that may contribute to hair loss, such as fungal infections. However, scientific studies specifically evaluating Babchi’s efficacy for hair regrowth or prevention of hair thinning are very limited. Some laboratory studies suggest Babchi extracts may have antimicrobial and anti-inflammatory properties, which could theoretically benefit scalp health, but clinical trials in humans for hair loss are lacking. Therefore, while traditional systems endorse Babchi for hair health, and anecdotal reports persist, the current scientific evidence supporting its effectiveness for treating hair loss or thinning remains weak.
