Does Olive Oil Make Hair grow?

Olive Oil does not make your hair grow. However, oil treatments (including olive, coconut, neem, peanut, and others) do help keep hair in tip-top condition. It will appear that your hair is growing faster simply because regular oil treatments will prevent breakage in your hair. So, will it grow faster? No. But because it prevents breakage your hair will be longer than it would without it. Maternal vitamins do help with hair growth (be aware that vitamins in a powder form i.e. not a hard capsule but rather a powder inside a gelatin type capsule allows for more absorption of the nutrients in the vitamin).
