A French braid is a popular hairstyle that involves weaving three sections of hair together. It starts at the top of the head and gradually incorporates more hair from the sides as you braid downwards. This technique creates a tight, elegant look that keeps hair neatly in place. French braids can be worn in various styles, such as a single braid down the back or two braids on either side of the head. They are suitable for different hair types and lengths, making them a versatile choice for both casual and formal occasions.
