Hair, Skin & Nail Health

Hair thinning, brittle nails, or skin changes can be linked to underlying nutrient and hormone levels. Ferritin, vitamin D, and thyroid function all play a role in hair, skin, and nail health, and are simple to check with finger-prick blood tests.

Order your tests online, take a small sample at home, and post it to our UK lab using the prepaid envelope provided. Results are typically ready within days, with clear reference ranges to discuss with your GP.

Hair, skin, and nail changes have many possible causes, including genetics, stress, and underlying health conditions. These tests are designed to help identify physical contributors alongside your symptoms, not to diagnose the cause on their own.
