A bun is a popular hairstyle where the hair is gathered and twisted into a round shape, typically secured at the back or top of the head. This style can be worn in various ways, including a sleek, tight bun or a loose, messy bun, depending on personal preference and occasion. Buns are often chosen for their practicality, as they keep hair neatly out of the face. Buns can be styled using different techniques and accessories, such as hair ties, pins, or decorative elements like flowers or ribbons. This versatile hairstyle is suitable for both casual and formal events, making it a favorite among many, including celebrities and everyday individuals.
