Hair Loss and Blood Testing - What Can Your Results Reveal

Hair Loss and Blood Testing – What Can Your Results Reveal?

Losing Hair? It Might Be More Than Just Genetics

If your hair is thinning, shedding more than usual, or receding at the hairline – blood tests can help uncover the real cause.

At Marylebone Diagnostic Centre, we offer private blood testing for hair loss in Central London, just minutes from Harley Street, Marylebone, and Paddington.

Our hair loss blood panels explore key causes including:

  • Thyroid dysfunction (TSH, T3, T4)
  • Iron & Ferritin deficiency
  • Vitamin D, B12, and Folate deficiency
  • Hormonal imbalance (Testosterone, SHBG, DHEA-S, Oestradiol)
  • Autoimmune markers (if needed)

All tests are reviewed by expert clinicians under our Marylebone High Standard™.

It’s Not Just Hair. It’s Your Confidence.

Hair loss can be distressing — especially when it starts suddenly, worsens quickly, or you don’t know why it’s happening.

We support men and women of all ages facing:

  • Postpartum hair thinning
  • Male pattern baldness
  • PCOS or hormone-related hair loss
  • Stress-related telogen effluvium
  • Nutrient deficiencies and anaemia
  • Thinning due to long COVID or chronic illness

At our discreet, boutique clinic in Marylebone, you’ll be treated with respect, understanding, and expert care – with no judgement, no long waits, and no rushed appointments.

FAQs – Blood Testing for Hair Loss in London

Can blood tests really explain hair loss?
Yes — in many cases, underlying causes like low iron, vitamin D, thyroid imbalance, or hormones are revealed through bloodwork.
Is this for men and women?
Yes. We have tailored options for both, including PCOS screening for women and testosterone checks for men.
How soon will I get the results?
Most results return within 24–48 hours, some same-day.
What if everything is “normal”?
Even within normal ranges, we interpret levels functionally, not just diagnostically. We explain all results clearly.
Do I need a referral?
No referral needed — you can self-book directly.
Will someone explain my results?
Yes. You’ll get a personalised report and optional follow-up if required.
Can I get treatment from you too?
We can recommend evidence-based supplements, lifestyle adjustments, or refer you to a hair restoration specialist.
Can hair loss be reversed?
It depends on the cause — many forms are reversible with the right diagnosis and early intervention.
Is this covered by insurance?
Some international clients are reimbursed — we provide invoices for claims.
Is the service private?
100%. We are trusted by doctors, business professionals, and high-profile clients.
