Thinning Hair

Rapid diffuse shedding after major illness, surgery, or severe stress warrants assessment even if spontaneous recovery is likely. Thinning alongside fatigue, cold intolerance, or weight change may indicate thyroid dysfunction. In younger women, thinning with menstrual irregularity and acne should prompt screening for PCOS. These are not reasons to panic — but they are reasons to see a qualified practitioner.

Minoxidil (topical or oral) is first-line for androgenetic alopecia with robust clinical trial support — worth discussing with a practitioner to assess suitability. Oral finasteride has strong evidence in men but carries a meaningful side-effect profile. Correcting iron deficiency, thyroid dysfunction, or zinc deficiency may support recovery of hair density where these are the underlying cause. Low-level laser therapy and platelet-rich plasma injections have emerging but more limited evidence.

Finasteride is absolutely contraindicated in women of childbearing potential due to teratogenic risk — this is a hard clinical boundary, not a precaution. He shou wu (fo-ti), used in traditional Chinese medicine for hair and ageing, has documented cases of serious liver injury. Anyone considering it should make an informed decision with awareness of this risk, ideally with practitioner guidance.

Ayurveda uses scalp oil treatments with herbs such as bhringraj, amla, and brahmi, alongside dietary support. Bhringraj has been studied in limited preliminary research, though evidence quality is low. Some preliminary research has compared rosemary oil applied topically to low-dose minoxidil, with mixed results — promising but not yet definitive. TCM approaches focus on systemic nourishment; he shou wu is traditional but carries hepatotoxicity risk requiring caution.

Telogen effluvium often resolves without intervention once the triggering stressor is addressed, typically within 6–12 months. Nutritional causes respond well to targeted supplementation when a deficiency is confirmed. Androgenetic alopecia is chronic and benefits from sustained evidence-based management. For complementary approaches, identifying whether thinning is effluvium, androgenetic, or nutritional in origin matters — the appropriate supporting strategy differs meaningfully by cause.

Many supplements marketed for hair growth — including high-dose biotin — lack robust evidence in people without a confirmed deficiency. PRP and LLLT show promise but study sizes remain small and protocols vary. Traditional herbal approaches are often under-researched by modern standards. Absence of strong evidence does not mean an approach is ineffective, but it does mean inflated outcome claims should be viewed critically.
