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.

Treatment, after the bloods

DHT-driven loss? WMG Meds picks up where the panel leaves off.

If your panel shows a DHT or nutritional cause we can treat, our sister service WMG Meds dispenses prescription hair-loss medication under continued clinical supervision from GMC-registered doctors at the same Harley Street group. No second consultation. No referral letter. The clinician who reads your results can hand the plan straight over.
