Blood Tests for Hair Loss

A doctor-led hair loss blood test in London at our Chelsea clinic identifies the medical drivers of thinning hair — iron, thyroid, hormones and inflammation — and turns them into a clear treatment plan.

What causes hair loss?

• Iron deficiency (low ferritin), the single most common cause of diffuse shedding
• Thyroid dysfunction
• Hormonal imbalance — androgens, oestrogen, perimenopause, post-partum
• Vitamin and mineral deficiencies — vitamin D, B12, zinc, biotin
• Chronic inflammation and autoimmune conditions
• Stress, illness or rapid weight loss (telogen effluvium)
• Insulin resistance and PCOS

What we test

Ferritin and full iron studies, full blood count, full thyroid panel with antibodies, vitamin D, B12, folate, zinc, magnesium, full hormone profile, HbA1c and fasting insulin, hsCRP and (where indicated) ANA.

Treatment

In-house options include scalp PRP, pharmaceutical-grade supplementation, hormonal correction, prescription topicals (minoxidil, finasteride/dutasteride where appropriate) and IV nutrient therapy.
