Design a floating, magical hairstyle that looks like it’s made of smoke and stardust. The hair should shift colors from deep violet to shimmering silver as it moves, with no visible strands — just smooth, flowing motion like cosmic energy. It should rise upward in defiance of gravity, like a crown of mist and galaxy light. Add subtle sparkles, glowing dust trails, and a mystical aura effect. The style should feel ancient and arcane, like a spellcaster from another dimension.
