Hair Loss in Men – Could a Blood Test Reveal the Cause?
By Tharb Faisl
Losing Hair? It Might Not Be Just “Ageing”. While male pattern baldness is common, not all hair loss is genetic. Hormone changes, nutrient deficiencies, and thyroid imbalances can all cause or worsen thinning hair.
That’s why at Marylebone Diagnostic Centre, we offer targeted hair loss blood tests for men looking to understand what’s going on beneath the surface — and how to fix it.

Why Testing Matters Before Treatment
Most men jump straight into topical solutions or hair transplants — but without testing, you might be missing a treatable underlying condition.
By identifying deficiencies or imbalances, you may be able to:
- Prevent further hair loss
- Improve results from hair restoration treatments
- Feel better overall (boost in energy, focus, mood)
