Begin by parting the hair down the center back and establishing a short, clean baseline at the lower nape hairline using precision shears. Create forty-five-degree diagonal sections starting from the center nape, elevating each tier to build a smooth, graduated stack that rounds over the occipital bone. Transition to the sides, extending the traveling guide along a forward downward angle toward the front jawline. Apply a quarter-sized amount of thermal styling serum throughout damp strands to defend against heat damage. Blow-dry the back layers using a small paddle brush wrapped around the head shape, then smooth the longer front pieces with a flat iron, angling the ends slightly inward toward the chin.
