Medical tests for hair loss, balding, thin hair, and Alopecia areata
Concerned about hair loss?
Hair loss can be distressing—but it can also be treatable when the cause is understood.
Whether you’re experiencing gradual hair thinning, early balding, sudden shedding, or patchy bald spots, the first step is identifying why it’s happening.At Regis Medical, we help you uncover the medical causes of hair loss through GP evaluation and targeted blood tests. We focus on diagnosing what’s beneath the surface—nutritional, hormonal, autoimmune, or stress-related factors—so you can take the right steps forward.
Why Get Tested for Hair Loss?
Hair loss isn’t just a cosmetic issue. It can be a symptom of deeper health concerns such as:
- Iron deficiency
- Thyroid dysfunction
- Vitamin D or B12 deficiency
- Hormonal imbalances
- Autoimmune conditions like Alopecia Areata
- Post-illness or post-pregnancy shedding
- Stress-related Telogen Effluvium
Treating the cause, not just the symptoms, can prevent further loss and support healthy regrowth.
What Tests Are Done for Hair Loss?
At Regis Medical, we offer a structured medical approach that includes GP evaluation and lab-based hair loss blood panels. These are designed to uncover the root causes of:
- Thinning at the scalp or part line
- Balding at the crown or temples
- Sudden hair fall or excessive shedding
- Patchy bald spots (suspected Alopecia Areata)
- Hair loss with fatigue, irregular periods, or weight changes

What to Expect During Your Visit
Step 1: Clinical Evaluation
Our GP will begin with a detailed consultation, reviewing:
- Pattern and duration of hair loss
- Recent illness, surgery, or emotional stress
- Family history of hair loss or autoimmune conditions
- Scalp condition (e.g. scaling, inflammation, scarring)
- Menstrual, metabolic, and dietary history (for female patients)
This helps us identify the likely cause of your hair loss, whether it is:
- Androgenetic alopecia (hereditary pattern hair loss)
- Telogen effluvium (stress-related shedding)
- Alopecia areata (autoimmune-related hair loss)
- Nutritional or hormone-related hair thinning
Step 2: Tailored Blood Test Plan
Based on your evaluation, the doctor will recommend a relevant blood panel. These tests can be done in-clinic or through our partner labs depending on your needs and timing.
Step 3: Results Review & Action Plan
- We explain your results clearly, without medical jargon
- If a deficiency or hormonal imbalance is found, we’ll guide you on next steps
- This may include nutrition advice, medication (e.g. iron or thyroid support), or a referral to a specialist
We don’t just test — we help you take the next step toward better hair and overall health.
Who Should Get Tested for Hair Loss?
Hair loss testing is suitable for individuals who may have underlying nutritional, hormonal, or autoimmune triggers. It is especially recommended for:
- Women with sudden hair fall or part-line thinning
- Men with early-onset balding or unexplained shedding
- Individuals recovering from COVID-19, surgery, or emotional stress
- People with patchy bald spots (possible Alopecia Areata)
- Those experiencing fatigue, cold sensitivity, weight changes, or other hormonal symptoms
It's also important to consult a GP if you notice any of the following signs:
- Sudden or excessive hair shedding
- Patchy or circular bald spots
- Thinning hair around the temples or crown
- Changes in scalp condition (redness, itching, scaling)
- Hair loss with fatigue, irregular periods, or unexplained weight changes
- A family history of autoimmune or hormonal conditions
Early evaluation helps identify reversible causes before they worsen—and gives you a clearer path to recovery.
