What blood tests can reveal
Nutritional deficiencies
Low ferritin, iron, zinc, vitamin D, and B12 are among the most common, and most treatable, causes of hair loss.
Hormonal imbalances
Excess DHT, elevated androgens, low oestrogen, and thyroid dysfunction all directly affect hair follicle health.
Thyroid dysfunction
Both overactive and underactive thyroid can cause significant shedding, yet are frequently missed without a full panel.
Autoimmune conditions
Scarring alopecias and alopecia areata require specific antibody and biopsy testing to diagnose accurately.
What happens after your results?
Your results are reviewed by a GMC-registered doctor who will flag any abnormalities, explain what they mean for your hair health, and outline clear next steps, whether supplementation, lifestyle changes, or further investigation.
