Female Hair Loss in Australia: Causes and Treatment Options
Hair loss is often thought of as a male issue. The data tells a different story. Around four in ten Australian women experience some degree of visible hair thinning by the age of fifty, and a significant proportion experience it earlier (Australasian College of Dermatologists, 2026). Despite that, it is one of the most under-discussed health concerns in Australian general practice. Women often live with it for years before raising it, partly because they assume nothing can be done, partly because they fear the conversation will be brushed aside.
The plain-English version is this. Hair grows in cycles. A growing phase, a transitional phase, and a resting phase, after which the hair falls out and the cycle starts again. Hair loss happens when the balance of these phases shifts, when the growing phase shortens, or when individual follicles begin to miniaturise and produce thinner hair. The cause can be hormonal, nutritional, autoimmune, stress-related, medication-related, or a combination. In many women, more than one factor is at play.
The most important thing to know is that female hair loss is investigable and, in most cases, treatable. Some patterns improve with simple changes. Others need ongoing treatment to slow progression. Either way, a GP is the right starting point. The window where treatment is most effective is usually earlier rather than later, which is why it's worth raising the conversation as soon as you've noticed a change.
This guide walks through the common patterns, the causes a GP will investigate, when to book an appointment, and the treatment options at the class level.

Female hair loss doesn't usually look like the male pattern. The mix below covers most of what Australian GPs see in practice.
Female pattern hair loss. The most common pattern, sometimes called androgenetic alopecia in women. Diffuse thinning across the top and crown, with the part line widening over time. The frontal hairline is usually preserved, which differs from the male pattern. Onset can be in the twenties, thirties, forties, or later, and there is often a family history.
Telogen effluvium. A diffuse shed across the whole scalp, usually two to four months after a trigger. Common triggers include childbirth, severe illness, surgery, COVID infection, rapid weight loss, iron deficiency, thyroid disease, and significant emotional stress. Telogen effluvium is typically reversible once the underlying cause is addressed, although it can take six to twelve months to recover visibly.
Postpartum hair loss. A specific form of telogen effluvium triggered by the hormonal changes after birth. Usually starts two to four months postpartum and resolves over six to twelve months. Common, distressing, and almost always self-limiting.
Alopecia areata. Patchy hair loss in well-defined circular or oval patches, usually on the scalp but sometimes on eyebrows or other body hair. Driven by an autoimmune process. The course is variable: some patches regrow on their own, others persist or progress.
Traction alopecia. Hair loss from sustained tension on the hair shaft, classically from tight ponytails, braids, weaves, or extensions. Most often along the frontal hairline and temples. Reversible if caught early; can be permanent if hair-pulling styles continue for years.
Scarring alopecias. A less common but important group of conditions where the follicle is destroyed and hair loss is permanent. Often presents with redness, itch, scaling, or tenderness of the scalp. Early diagnosis matters, because treatment can stop progression but cannot reverse what is already lost.
Mixed patterns. Many women have a combination, for example, female pattern hair loss running in the background with a recent telogen effluvium overlaid on top. Untangling the mix is part of what a GP does at the consult.
Hair has a long memory. By the time you notice a visible change, the trigger may have been months in the past. A good GP review takes that into account.
Iron deficiency. Common in Australian women, particularly those with heavy periods, restrictive diets, or recent pregnancies. Low ferritin (the body's iron store) is a frequent and easily correctable contributor to hair loss.
Thyroid disease. Both an underactive and an overactive thyroid can drive hair loss. A GP will usually check thyroid function as part of a hair loss workup, because the hair changes can be the first sign of thyroid disease in some women.
Vitamin B12 and vitamin D. Both can play a supporting role, particularly in women on restrictive diets, those with absorption issues, or those with limited sun exposure. A GP will assess whether testing is appropriate.
Hormonal contributors. The hormonal shifts of perimenopause, menopause, polycystic ovary syndrome (PCOS), pregnancy, and the postpartum period all influence hair growth. PCOS in particular is associated with female pattern hair loss in younger women, often alongside other features such as acne or irregular periods.
Stress and sleep. A reliable trigger for telogen effluvium, often three to four months after a high-stress period.
Crash diets and rapid weight loss. A reliable trigger of telogen effluvium. Bariatric surgery and very low-calorie diets are common precipitants.
Medications. A range of medication classes can contribute to hair loss. A GP will review your full medication list at the consult.
Recent illness or infection. COVID-19, in particular, has been a major driver of telogen effluvium in Australian women over the past few years.
Autoimmune conditions. Alopecia areata sits alongside other autoimmune conditions in some patients. A GP may screen if there are other features in the history.
Scalp conditions. Seborrhoeic dermatitis, psoriasis, and other inflammatory scalp conditions can cause hair loss in their own right, and can amplify other patterns.
A GP will not test for every possible cause. The investigations are matched to the history and the pattern of loss.
Some hair shedding is normal. Most people lose around fifty to one hundred hairs a day. The threshold for booking an appointment is when the change is noticeable to you, not when the pattern matches a textbook image.
Book an appointment if:
- You're noticing a wider part line or your ponytail feels thinner
- You're shedding more than usual for more than three months
- A patch of hair has appeared with no obvious cause
- You're postpartum and the shedding hasn't settled by twelve months
- You're seeing scalp redness, scaling, itch, or pain
- The change is affecting your mood, confidence, or daily life
See a GP sooner rather than later if:
- A scarring scalp condition is suspected (redness, scaling, scarring patches)
- The hair loss is rapid or severe
- You have other symptoms that suggest a thyroid issue, PCOS, or another underlying condition
- You're losing eyebrows or eyelashes as well as scalp hair
The reason for not waiting is straightforward. Treatment is more effective when started earlier. For inherited patterns, slowing progression is the realistic goal, and the earlier you start, the more hair there is to protect. For reversible causes, the longer the trigger sits unaddressed, the longer recovery takes.
An Australian GP is the right starting point for hair loss, and for most women they'll also be the right ongoing point of care. Specialist dermatology referral is reserved for scarring alopecias, treatment-resistant cases, and certain procedural options.
A consult typically includes:
A thorough history. A GP will ask about the timeline (when did you notice the change), the pattern (diffuse vs. patchy, frontal vs. crown), family history, periods and pregnancies, medications, recent illnesses, weight changes, diet, and stress over the past year. Hair loss has a delayed clock: the trigger is often months earlier than the visible change.
A scalp examination. A focused look at the scalp, the part line, the frontal hairline, and any patchy areas. Photos taken in good light from consistent angles are useful for ongoing review.
Investigations where appropriate. A standard workup often includes a full blood count, ferritin (iron stores), thyroid function, and vitamin B12, sometimes with vitamin D, and selectively, hormonal testing if PCOS or another hormonal condition is suspected. A GP will explain the rationale for each test.
Treatment categories at the class level. A GP will walk through the evidence-based options. Choices are discussed in categories rather than specific brands, because the right combination depends on the cause, the pattern, and your individual context.
- Treat the underlying cause first. Iron replacement for low ferritin, thyroid treatment for thyroid disease, vitamin replacement where indicated. In many women, this alone produces a significant improvement.
- Topical hair-growth treatments. A first-line class for female pattern hair loss, applied to the affected areas of the scalp daily. Used long-term, with results typically visible after three to six months.
- Oral treatment classes. Several oral medication classes are used for female pattern hair loss in particular contexts. Options vary depending on the cause, hormonal profile, and other health considerations, and a GP will discuss which classes are appropriate for you.
- Topical and intralesional anti-inflammatory treatments. Used in alopecia areata to slow patches and encourage regrowth.
- Procedural options. Platelet-rich plasma injections, low-level laser therapy, and hair transplantation are usually arranged through a dermatologist. Evidence and access vary; a GP can advise on whether referral is appropriate.
- Lifestyle and supportive measures. Gentler haircare, avoiding tight hairstyles, sensible nutrition, sleep, and stress management. Often unglamorous, often part of a plan that works.
Ongoing review. Hair grows slowly, which means treatment plans are reviewed in months, not weeks. A GP will usually book a follow-up at three months and again at six months to assess response and adjust.
Online appointments for hair loss care
Abby Health is an online-first clinic where Australian GPs see patients seven days a week. Hair loss is one of the most common reasons women book an appointment with us, and our clinicians take it seriously. It is not vanity, and we don't treat it as such.
The format suits this kind of care. Photos taken in consistent light, from consistent angles, allow a GP to assess the pattern and to track changes over time. Many women find the conversation easier from their own home. Continuity is built in: the next time you see an Abby GP, your previous photos, results, and plan are already in front of them, so you don't have to start the story again. Abby AI, our medical AI, supports the clinician by surfacing your history before the consult, and never replaces clinical judgment.
Where blood tests are needed, a GP can issue a request form so you can attend a local pathology collection centre. Where a prescription is appropriate, our clinicians can issue online prescriptions. Where a hands-on dermatology review is genuinely needed, a GP will say so and arrange referral.
Abby Health is bulk billed for eligible patients with a valid Medicare card. Strict eligibility criteria apply. To start, schedule an appointment.
Will I get my hair back?
This depends on the cause. Telogen effluvium typically resolves on its own once the underlying trigger has been addressed, with hair returning over 6 to 12 months. Female pattern hair loss does not reverse but can often be slowed or partially improved with treatment. Scarring alopecias cause permanent loss in the affected follicles, which is why earlier review matters. Your GP will discuss what is realistic for your specific pattern.
Are there blood tests I should ask for?
A standard workup includes full blood count, ferritin (iron stores), thyroid function, and vitamin D. Depending on your history, additional tests may be appropriate including hormonal tests, vitamin B12, zinc, or autoimmune markers. Your GP will tailor the panel to your situation.
Are over-the-counter treatments worth trying first?
Some are useful, others are marketing. A short conversation with a clinician before spending money on shampoos, supplements, or topical products is generally a good idea. Most over-the-counter hair products do not address the underlying cause, and supplementing iron, vitamin D, or other nutrients without testing first is not recommended.
Do I need to see a dermatologist?
Many cases are managed in primary care. A dermatology referral is appropriate where the diagnosis is uncertain, where scarring is possible, where standard treatment is not working, or where a more specialised workup is needed. Your GP will discuss whether a referral fits your situation.
Will medication for hair loss affect my ability to get pregnant?
Some hair loss treatments are not appropriate during pregnancy, breastfeeding, or for women planning a pregnancy. This is one of the most important reasons to have the conversation with a clinician before starting any prescription treatment. Your GP will discuss what is and is not appropriate given your current and planned circumstances.
