  "what": "Hair regrowth treatment aims to reactivate follicles that have miniaturised but not died, rather than just slowing loss. At Dr Sin Yong's practice on Orchard Road, Singapore, the plan combines Regenera Activa autologous micrografts, laser hair stimulation including the 1540 nm protocol he published in PRIME Journal, and medical therapy where indicated, sequenced after Norwood or Ludwig staging and trichoscopy. Follicles that are genuinely gone cannot be recreated, and a smooth, shiny zone is referred for a hair transplant assessment.",
  "key_facts": [
    "Staging: history, scalp examination and trichoscopy establish the Norwood or Ludwig stage, miniaturisation pattern and donor integrity; women are screened for other drivers such as a deficiency or a thyroid problem",
    "Regenera Activa: millimetre punch grafts from the occipital scalp are processed chairside into a cell-rich suspension and delivered to thinning zones",
    "Laser stimulation (H2LT): fractional laser scalp stimulation, including the 1540 nm erbium-glass protocol Dr Sin Yong published in PRIME Journal (Nov/Dec 2023)",
    "Medical therapy: the androgen pathway is treated medically where appropriate, including a discussion of who should not take it",
    "Adjuncts: polynucleotides and topical exosomes can support the protocol but are not standalone treatments",
    "Referral: alopecia areata goes to dermatology and a bare, stable zone to a hair transplant assessment; Dr Sin Yong is an aesthetic physician, not a registered specialist",
    "Review: progress is compared against baseline trichoscopy and standardised photographs; micrografting and laser treatments are performed personally by Dr Sin Yong"
