Olive oil has been known to have several benefits for hair growth. It contains oleic acid, phenolic constituents, and squalene, which are the chief active components of olive oil
. These components help to nourish and moisturize the scalp, which can promote hair growth. Olive oil also contains antioxidants that can help to protect the hair from damage caused by free radicals
. However, there is no scientific evidence to support the claim that olive oil can directly stimulate hair growth. It is important to note that using too much olive oil on the hair can make it greasy and weigh it down
