The "Rachel haircut" is a layered hairstyle that became popular in the 1990s, primarily due to the character Rachel Green from the television show Friends. This haircut features face-framing layers, volume at the crown, and a slightly longer length in the back, creating a soft, bouncy look. Designed by hairstylist Chris McMillan, the Rachel haircut was characterized by its versatility, making it suitable for various hair types and lengths. It quickly became a trend among women, symbolizing the chic and casual style of the era, and remains a reference point in hair fashion today.
