Does Oleic acid cause hair loss?

There is no scientific evidence to suggest that oleic acid directly causes hair loss. Oleic acid is a monounsaturated fatty acid found in many vegetable oils, including olive oil, which is commonly used in hair care products. While certain conditions and factors such as genetics, hormonal changes, medical treatments, nutritional deficiencies, and stress can affect hair growth and lead to hair loss, there is no specific link between oleic acid and hair loss.
