A "short layer hair cut" is a hairstyle characterized by short, stacked layers cut into the hair to create volume and movement. An example of this haircut is the classic "Rachel" haircut, popularized by Jennifer Aniston in the 1990s sitcom "Friends".
Short layer hair cuts are versatile and flattering for many face shapes and hair types. They can be tailored to individual preferences, with the length and number of layers varying. This haircut adds volume and bounce to fine hair, and it can help to soften the appearance of a round face.
