  intro: "Scalp massage became a trend because it's unusually immediate: you can feel it working in under a minute. What it does is less complicated than the marketing suggests. Consistent mechanical pressure increases blood flow to the follicle, loosens product and sebum build-up, and — with long-term practice — may increase follicle diameter. You don't need a device. You don't need oil. You need two minutes and the right hand position, done regularly enough to matter.",

    body: "Scalp massage works through mechanical stimulation: fingertips applying consistent downward pressure in small circular movements increase dermal blood flow to the hair follicle. Secondary effects include loosening of product residue, temporary sebum redistribution, and — reported in several small studies — an increase in hair shaft diameter after daily practice over 24 weeks.",

    { m: "You need oil or a serum for massage to work.",

    { m: "Harder pressure means better results.",
      t: "The goal is moving the scalp tissue against the skull, not compressing it. Medium consistent pressure in small circles. Pressing harder moves less tissue, not more." },
    { m: "Massaging the ends and mid-lengths helps too.",
