This review looked at rosemary oil and other natural ingredients for hair loss, especially the genetic kind (androgenetic alopecia). The researchers found that while rosemary oil is popular and shows promise, most natural remedies need more rigorous testing to prove they actually work—right now, only two FDA-approved drugs (finasteride and minoxidil) have solid evidence behind them.

This was a review article that examined existing studies on herbal treatments for hair loss, with a focus on rosemary oil. The authors compiled findings from multiple clinical studies testing various plant-based ingredients.
