The trick isn’t just the style—it’s knowing how to prep the hair with the right thermal protectants and choosing a flat iron that matches your hair’s texture. Ceramic plates work best for fine hair, while titanium glides smoother on coarser strands. Don’t forget: too much serum can make it look greasy, not flat.
