How to Wash & Style Curly/Wavy Hair Upside Down (Without Wonky Curls!) Tip 1: Rotate your head from side to side while washing and styling. This helps lift your roots and prevents flat or “wonky” sections in the back. Tip 2: Shake your hair before scrunching. This encourages your curls/waves to form in their natural direction, reducing frizz and uneven curl clumps. Perfect for anyone with wavy hair, curly hair, or learning the upside-down wash routine.
