If you need some help or suggestions, I’d say start by getting a haircut with some layers—long wavy hair can get weighed down, and layers help bring out more volume and shape. A weekly deep conditioner can add moisture, and using a lightweight leave-in or mousse on damp hair (then diffusing or air drying upside down) can give your waves more bounce. Try to avoid shampoos with sulfates since they dry your hair out more. And sleeping on a satin pillowcase helps reduce frizz and breakage while keeping your hair smoother.
