Beta-Sitosterol
Ingredient Info
Beta-sitosterol is a plant-derived compound found in oils like saw palmetto that may help reduce hair loss and support scalp health. It works by potentially lowering levels of DHT, a hormone linked to hair thinning in genetically susceptible individuals.
Benefits
- May reduce hair fall by up to 22-29% when used topically or orally
- May increase hair density and thickness
- Generally well-tolerated with no serious adverse effects reported in clinical studies
Science: A 16-week randomized controlled trial found that topical and oral saw palmetto oil formulations (containing 2-3% beta-sitosterol) significantly reduced hair fall and increased hair density in subjects with androgenetic alopecia, with oral administration also reducing serum DHT levels. Effects on hair growth cycle were less pronounced.
