  intro: "Scalp oiliness is not the same problem as facial oiliness, even though the same sebaceous logic applies. The hair shaft itself becomes the delivery mechanism — oil travels down from the follicle, coating each strand with a film that turns roots flat and ends greasy. Genetics set the baseline. But wash frequency, product residue, diet, hormones, and the temperature of your shower water all modulate the daily output. The fix is not always washing more — in many cases it is the precise opposite. Below is everything we've published on scalp oiliness and the routines that calm it.",

    body: "The scalp is the densest concentration of sebaceous glands on the body. Sebum is healthy and necessary — it protects the scalp's skin barrier and lubricates the outer cuticle. The concern arises when output exceeds what the scalp's microbiome and skin barrier can process, or when washing habits reinforce the overproduction cycle rather than calming it.",

    { m: "Washing more often will fix it.",

    { m: "Oily scalp and dry ends don't go together.",
      t: "This is one of the most common hair realities. The scalp overproduces; the ends never see enough sebum to stay lubricated. A routine has to address both at once, with zone-specific application." },
