  intro: "Heat damage isn't about the tools you use — it's about how you use them. The three techniques on this page share a common mistake: people skip the prep and blame the result. Sectioning tells the heat where to go. Rough-drying takes the weight out before any tool touches the hair. Diffusing coaxes the curl rather than fighting it. Get the sequencing right and the heat becomes a precision instrument, not a hazard.",
