Have you tried this? Using your diffuser to scrunch out the cast will dry any remaining dampness and create extra volume.
1. After styling, diffuse until your hair is dry.
2. Optional: Use root clips along the top to add volume while the hair sets.
3. Remove the clips and fluff out the roots using dry hands. Scrunch out the cast.
4. For added volume and to dry any remaining dampness, use your diffuser on low heat and low speed to finish drying. Use the prongs to lift the roots.
