The term 'high coif' is a hairstyle that involves the hair being pulled up and away from the face. The most common way to achieve this look is with an updo, which is a four-letter word that is often used to describe this style. An updo is a hairstyle that involves the hair being pinned or tied up in a way that creates a more formal look. This style is often seen at formal events such as weddings and proms, and can be achieved with various techniques such as braiding, twisting, and pinning.
