Long bobs can indeed have layers, and adding layers to a lob can create a more dynamic and textured look. Layering can add movement, volume, and shape to the haircut, making it more visually interesting. Layered lobs are particularly suitable for those with thick or wavy hair, as the layers can help reduce bulk and make the hair more manageable. However, even those with fine or straight hair can benefit from strategically placed layers to give the illusion of fuller, more voluminous locks. When getting a layered lob, it's essential to consult with your hairstylist to determine the best layering technique for your hair type and face shape.
