What is an edge up?

An edge up is a type of men's haircut that involves shaping the hairline at the front of the head with a straight razor or electric clippers. It is usually done to create a cleaner, more defined hairline and is popular for men with short haircuts or fades. The edge up can also be referred to as a line-up or shape-up. It is important to note that edge ups should only be performed by a skilled barber or hair stylist to avoid injury or mistakes in the shaping of the hairline.
