    Hair Follicle Stimulation

    Promoted hair growth through follicle activation.

    TL;DR

    Hair loss has a cause — androgenetic, nutritional, thyroid or telogen effluvium — and treatment depends on which. Correcting iron and thyroid problems works; biotin only helps if you are genuinely deficient.

    Why It Matters

    Sudden diffuse shedding usually reflects telogen effluvium from illness, surgery, childbirth, crash dieting or iron deficiency, and typically recovers. Progressive patterned thinning is androgenetic and needs different treatment.

    How to Measure

    Biomarkers

    Ferritin
    TSH and free T4
    Full blood count
    Vitamin D
    Hair pull test
    Standardised photographs

    Optimization Protocol

    Test ferritin, thyroid function and full blood count before supplementing, and aim for ferritin above 50 ng/mL if shedding is diffuse. Ensure adequate protein and total energy intake. For patterned loss, topical minoxidil and medical review are the evidence-based options. Take photographs monthly, since regrowth takes three to six months to become visible.
