Female hair loss is often multifactorial — driven by hormonal imbalances, iron deficiency, thyroid dysfunction, and nutrient gaps. This panel tests iron stores (ferritin + iron panel with TIBC), hormonal factors including androgens that can cause thinning in women (total and free testosterone, DHEA-S, SHBG), reproductive hormones (progesterone, estradiol, prolactin) whose imbalances correlate with hair shedding, complete thyroid function (TSH, free T3, free T4, reverse T3), and nutrients essential for hair growth (vitamin D, B12, zinc, biotin, copper, selenium). This panel is ideal for women experiencing diffuse thinning, excessive shedding, or slow growth — especially postpartum, perimenopausal, or with suspected PCOS.
Hormone testing measures the chemical messengers that regulate energy, mood, sex drive, weight, and reproduction — helping pinpoint imbalances that cause a wide range of symptoms.
Anyone with unexplained fatigue, mood changes, libido changes, weight changes, irregular cycles, or considering hormone replacement therapy.

Oral contraceptives and estrogen, common medications and biotin supplements can change a Women's Hair Health Panel result without anything being wrong. Oral contraceptives and estrogen can raise SHBG, Free T3 and Ferritin and can lower Total Testosterone and Estradiol — expected; interpret testosterone with it. Common medications can raise SHBG and can lower Total Testosterone and Vitamin B12 — free testosterone and SHBG interpreted in that context. Biotin supplements can falsely lower TSH and can falsely raise Free T3 and 25-Hydroxy Vitamin D — stop biotin ≥72 hours before the draw. Each factor is covered on our physician-reviewed "Before your test" pages; when one applies, the fix is usually to remove it and retest.
