9. Julia Roberts
Julia suggests using olive oil to condition your hair – and it’s not actually crazy. Olive oil is incredibly rich in vitamin E which is known to help in the reduction of stretch marks, treat eczema and psoriasis, moisturize dry nails and cuticles, treat chapped lips and cold sores, treat sunburn, and even slow down the signs of aging. Roberts uses olive oil by rubbing it into her skin and hair to help regenerate cells and promote shine, but there are a ton of other health benefits as well.
