Hair weaves are a popular method of adding length and volume to natural hair. They involve sewing or gluing extensions made from either synthetic or human hair onto the natural hair. This technique allows individuals to change their hairstyle without altering their natural hair permanently. Weaves can be styled in various ways, including straight, wavy, or curly, depending on personal preference. They require proper care to maintain their appearance and can last several weeks to months. Regular maintenance, such as washing and conditioning, is essential to keep both the weave and natural hair healthy.
