Loading symptom information
Thinning, shedding, or bald patches on the scalp. Can be caused by genetics, hormones, stress, nutritional deficiencies, or autoimmune conditions.
There are several possible causes. Here are the most common ones:
Genetic hair loss — the most common type.
You might suspect this if you have:
Temporary shedding 2-3 months after a stressor.
You might suspect this if you have:
Low iron, zinc, or vitamin D can cause hair loss.
You might suspect this if you have:
Both hypo- and hyperthyroidism cause hair loss.
You might suspect this if you have:
Autoimmune patches of hair loss.
You might suspect this if you have:

Hair loss consultations have increased significantly in telehealth — likely because patients find it easier to discuss a sensitive topic from home. The diagnostic approach starts with the pattern: is it diffuse (all over) or patchy? Gradual or sudden? Diffuse gradual thinning in a typical pattern strongly suggests androgenetic alopecia (genetic). Diffuse shedding 2-3 months after a stressor (illness, surgery, childbirth, severe stress) is telogen effluvium — this is fully reversible. Patchy loss with smooth skin suggests alopecia areata. I always check for treatable causes: iron, ferritin, thyroid function, zinc, and vitamin D — these are all correctable and commonly overlooked. For androgenetic alopecia, the key message is that early treatment (minoxidil ± finasteride for men) is far more effective at preventing further loss than trying to regrow what's already gone.
Medical certificate guidance: Hair loss itself is unlikely to require a medical certificate, but the psychological impact can be significant. If hair loss is causing anxiety or depression that affects work, that is a legitimate reason for support.
All clinical decisions are made by AHPRA-registered doctors following our clinical governance framework. We never automate clinical decisions.
Yes. A doctor can identify the cause (blood tests for deficiencies, thyroid, hormones), prescribe treatments (finasteride, minoxidil, iron supplementation), and refer to a dermatologist if needed.
It depends on the cause. Telogen effluvium (stress-related) is fully reversible. Iron/thyroid-related hair loss reverses with treatment. Pattern hair loss can be slowed and partially reversed with early treatment but is progressive without it.
Minoxidil (topical, OTC), finasteride (prescription, for men), iron/vitamin supplements if deficient, and referral for PRP therapy or specialist treatments for resistant cases.
If your symptoms are keeping you from work or study, you can request a medical certificate through InstantMed. A doctor will review your symptoms and issue a certificate if clinically appropriate — typically for 1 to 3 days depending on severity. You don't need to be dramatically unwell; feeling genuinely too rough to function is reason enough.
Yes. Australian-registered doctors can assess your symptoms and issue valid medical certificates via telehealth. You fill in a detailed health questionnaire, a doctor reviews it, and if appropriate, your certificate is delivered digitally. No waiting room required.
You complete a structured health questionnaire covering your symptoms, duration, severity, and relevant medical history. The reviewing doctor uses this information — the same clinical reasoning they'd apply in a face-to-face consult — to determine whether a certificate, advice, or referral is appropriate.
A medical certificate covers the period stated on the document. If your symptoms worsen or don't improve as expected, you should see a GP in person or visit your nearest emergency department if it's urgent. Your certificate doesn't replace ongoing care — it's a point-in-time clinical assessment.
In some cases, yes. If a doctor reviewing your request determines that a common, non-restricted treatment is appropriate, they may issue a prescription as part of a consultation. Not all symptoms require or qualify for a prescription — the doctor will advise you on next steps.
Medical certificates are typically issued in under 30 minutes, available 24/7. Other requests are reviewed within 1–2 hours during operating hours (8am–10pm AEST, 7 days). You'll receive an email notification once your request has been reviewed.
If your symptoms suggest something that requires a physical examination, diagnostic tests, or specialist referral, the doctor will let you know and recommend appropriate next steps. Your safety is the priority — telehealth is a great option for many things, but it's not a replacement for hands-on assessment when that's what's needed.
No Medicare card is required for medical certificates. If you're requesting a prescription or consultation, a valid Medicare card is needed. Our service is private and does not attract a Medicare rebate, though any prescriptions issued can still attract PBS subsidies at the pharmacy.
Our Australian-registered doctors can assess your symptoms and provide advice, treatment, or medical certificates if needed.
