SelectedThe Male Hair Loss Profile is a comprehensive blood test designed to identify underlying medical causes of hair thinning or hair loss in men. While genetics play a role, many men experience hair loss due to hormone imbalance, nutrient deficiency, thyroid dysfunction, or metabolic stress.
This profile includes:
Hormones
Testosterone
Free Testosterone (calculated)
Sex Hormone Binding Globulin (SHBG)
Follicle Stimulating Hormone (FSH)
Luteinising Hormone (LH)
Prolactin
DHEA-S
Cortisol
Oestradiol
Thyroid Function
Thyroid Stimulating Hormone (TSH)
Free T4
Nutrients & Health Markers
Vitamin D
Vitamin B12
Folate
Zinc
Ferritin
Liver & Kidney Function
Comprehensive Liver Function Test (LFT)
Renal Panel (excluding potassium, sodium, chloride, bicarbonate)
Full Blood Count
Full Blood Count (FBC)
Together, these markers provide a holistic assessment of factors that influence hair follicle health, hormone balance, energy levels, and overall wellbeing.
Male hair loss is often attributed solely to genetics, but many treatable or modifiable factors can accelerate hair thinning or worsen pattern hair loss. Identifying these issues early allows for targeted intervention rather than guesswork.
This profile helps determine whether hair loss is driven by hormonal imbalance, nutrient depletion, thyroid dysfunction, stress hormones, or systemic health issues.
You may benefit from this test if you experience:
Receding hairline or crown thinning
Sudden or accelerated hair shedding
Thinning hair despite hair loss treatments
Low libido or erectile changes
Chronic fatigue or low energy
Increased stress or poor sleep
Weight or muscle mass changes
Family history of early hair loss
Identifies hormonal drivers of hair loss
Assesses androgens, oestrogen balance, and pituitary hormones.
Detects thyroid-related hair thinning
Thyroid dysfunction is a common but overlooked cause.
Assesses nutrient deficiencies
Zinc, ferritin, B12, folate, and vitamin D are critical for follicles.
Evaluates stress hormone impact
Cortisol imbalance can disrupt hair growth cycles.
Supports libido and energy assessment
Hormones affecting hair also influence sexual health and vitality.
Checks liver and kidney processing
Ensures hormones and nutrients are metabolised effectively.
Screens for anaemia or inflammation
FBC helps identify systemic contributors to hair loss.
Supports personalised treatment planning
Enables targeted medical or nutritional intervention.

Both services are available UK-wide.
Low ferritin, zinc, vitamin D, or B vitamins may impair hair follicle growth and regeneration. Hormonal imbalances such as low testosterone, elevated oestradiol, or abnormal cortisol may disrupt the hair growth cycle.
Thyroid dysfunction can also contribute to diffuse thinning or shedding.
UK reference interpretation:
Abnormal: Outside laboratory reference ranges
Results within range suggest that hair loss is less likely driven by nutritional, hormonal, or metabolic factors. Genetic or androgen sensitivity may be more relevant in this context.
These results help rule out medical contributors.
UK reference interpretation:
Normal: Within laboratory reference ranges
Many men show a combination of mild deficiencies and hormonal shifts rather than a single cause. Addressing these collectively often improves hair quality, energy, and overall health.
Clinical context is essential for interpretation.
UK reference interpretation:
Mixed: Some markers outside reference ranges

WhatsApp UsFollow these guidelines for accurate results
Where possible, attend your blood test between 7am and 12pm. Please wait until any short-term illness or infection has fully resolved before testing. Avoid intense exercise for 24–48 hours beforehand, as this can affect certain markers.
Fasting is not always required, but some tests may recommend it. If fasting is advised, avoid food for 8–12 hours before your appointment and drink water only. Stay well hydrated, as this helps with sample collection and accuracy.
Continue prescribed medications unless advised otherwise by your clinician. Avoid vitamin, mineral, or biotin supplements for at least 24–48 hours before your test, as these can interfere with results. If you are unsure about any medication or supplement, please let us know before your appointment.
For hormone-related tests, timing within your menstrual cycle may be important. If relevant, follow any specific guidance provided on your test page.
If you have any questions or special circumstances, our team is happy to advise before your appointment.
