  intro: "Sulphates and silicones became villains at roughly the same time — around the mid-2000s, when the natural beauty movement found its first viral talking points. Both fell from grace without a rigorous trial. Neither is as simple as its detractors suggest, nor as harmless as its defenders claim. What they share: they do different things to different hair, and the hair on your head is the only evidence that matters.",

const SULPHATE_FACTS = {
  defn: {
    h: "What sulphates actually do",
    body: "Sulphates — primarily sodium lauryl sulphate (SLS) and sodium laureth sulphate (SLES) — are surfactants: they lower surface tension between water and oil, allowing sebum, product residue, and environmental grime to rinse away. They are effective, inexpensive, and have been in shampoos since the 1930s.",
  },
  myths: [
    { m: "Sulphates damage hair.",
      t: "They can. At high concentrations, SLS roughens the cuticle — measurably. But the concentration in most shampoos and the contact time of a rinse-off product change the picture significantly. SLES is considerably milder than SLS and is the variant in most mainstream formulas." },
    { m: "Everyone should go sulphate-free.",
      t: "Fine hair, oily scalps, and people who co-wash rarely (or never) tend to need a surfactant that clears product buildup properly. Silicone-heavy products in particular need a sulphate or a comparable surfactant to clear. Going sulphate-free without adjusting everything else is how you get residue." },
    { m: "Sulphate-free is always gentler.",
      t: "It depends entirely on the alternative surfactant. Some sulphate-free formulas use harsher alternatives. 'Sulphate-free' is a marketing claim, not a mildness guarantee." },
  ],
};

const SILICONE_FACTS = {
  defn: {
    h: "What silicones actually do",
    body: "Silicones are a family of synthetic polymers — the most common in hair care being dimethicone, cyclopentasiloxane, and amodimethicone. They coat the hair shaft, reduce friction between strands, add slip to detangling, and create a smoothed-cuticle appearance. They do not penetrate the cortex: their action is entirely on the surface.",
  },
  myths: [
    { m: "Silicones coat your hair and suffocate it.",
      t: "Hair does not breathe. The cuticle is inert protein. The 'suffocation' argument has no biological mechanism behind it. What silicones do do is build up on the hair surface over time if not regularly cleared — which changes the texture and reduces the effectiveness of moisture-based products." },
    { m: "Water-soluble silicones don't build up.",
      t: "Most 'water-soluble' silicones still require a surfactant to clear effectively. The difference from non-soluble variants is one of degree, not kind." },
    { m: "Silicones are permanently damaging.",
      t: "Silicone buildup is reversible. A clarifying wash removes it. There is no evidence of long-term structural damage from silicone use in normal concentrations." },
