When choosing a designer durag, consider the material it is made of. Look for durags made from high-quality fabrics such as silk or satin, as they are gentle on your hair and help to prevent frizz and breakage. Additionally, consider the size and fit of the durag. It should be large enough to cover your hair completely and snug enough to stay in place without causing discomfort. Lastly, choose a designer durag that matches your personal style and preferences, whether it's a bold pattern, a solid color, or a branded design.
