Much of saw palmetto's popularity as a remedy for hair loss and baldness, however, is based on how it's believed to work rather than on evidence that it actually does. Although there have been some lab studies showing that saw palmetto can inhibit 5-alpha- reductase, there are no well-designed clinical studies showing that saw palmetto can cause hair growth, or stop hair loss or baldness from progressing. One of the only published trials on saw palmetto for baldness is a small study involving 10 men with mild to moderate male pattern baldness. Although promising, the study was too small to provide meaningful evidence.
鋸棕櫚對脫髮有一定作用，然而它是基於理論的基礎上而沒有足夠的實踐證據來支持這一點。有的實驗室證明它能夠抑制5-alpha-reductase，但是沒有臨床試驗證明它能夠使頭髮生長。唯一的臨床試驗，只是涉及到10人輕中度脫髮者。
