Yes, styling powder can be used on curly hair to add volume, texture, and control. However, it is important to choose a styling powder that is specifically designed for curly hair to avoid any potential drying or frizzing effects. Look for products that are lightweight and contain ingredients that provide moisture and enhance the natural curl pattern. Additionally, it's advisable to apply the powder sparingly and evenly throughout the hair to achieve the desired effect without weighing down the curls. Remember to always follow the instructions provided by the product manufacturer for best results.
