  deck: "Lightening is the most complex colour service in the salon. It requires lifting existing pigment from the hair before depositing anything new. Done patiently and correctly, it transforms. Done quickly or without support, it causes breakage, brassiness, and months of repair.",
  intro: "The lightening process works by using hydrogen peroxide and alkaline bleach to break apart the melanin molecules inside the hair cortex. Natural dark pigment (eumelanin) breaks down through a predictable sequence of warm tones: black to red to orange to yellow to pale yellow. Each stage requires more processing and more damage to the structure. Going from level 3 (dark brown) to level 10 (platinum blonde) in a single session isn't possible without breaking the hair — which is why a colour roadmap, patience, and bond-building treatments aren't optional. Below is everything: the lift sequence, developer choices, single vs multi-session timelines, and what to do with the brass.",

    body: "Hair colour is measured in levels 1–10, from black to lightest blonde. Bleach lifts the hair through a predictable warm-tone sequence. Dark brown hair passes through red, then orange, then gold, then pale yellow before reaching platinum. Each stage takes time and causes structural damage. You cannot skip stages. Attempting to rush the process either breaks the hair or leaves it at the orange or yellow stage — which is not a failure of the bleach, but a sign the process needs another session.",
