Given the company is based in Israel I suspect he is a practicing orthodox Jew (hence the hairstyle typical of the followers of that religion). Quite common and typical where hes from, so not a bad hairstyle simply a religious belief. His choosen hairstyle has no bearing on his ability to run this company or not, no more that a Seek wearing a turban or a Buddist who shaves his head and wears the Chivara (orange robes).
