Gotten a new haircut?

Hi there, I loved your idea of hair oil. But tell me, will it look good on medium-size hair? My wife is using medium length haircuts https://glaminati.com/medium-length-hairstyles-long-thick-hair/ to find a new style for me, but I am not sure that oil will not make my near hairdo look a bit greasy. Just let me know what your experience tells you.
