Androgenic Alopecia vs Telogen Effluvium — Understanding the Difference
Two of the most common causes of female hair loss in Australia are androgenic alopecia and telogen effluvium.
On the surface, they can appear similar — thinning hair, reduced density, a scalp that feels more visible than it once did. But beneath that similarity sit two very different conditions, with very different timelines and very different outcomes.
Understanding which one you are experiencing is the first step toward choosing the right solution — and avoiding unnecessary stress or incorrect treatment.
What Is Androgenic Alopecia?
Androgenic alopecia, often referred to as female pattern hair loss, is a hereditary condition that causes gradual, progressive thinning over time.
It is influenced by genetic and hormonal factors — particularly dihydrotestosterone (DHT), a hormone that binds to receptors in the hair follicle and slowly miniaturises it. As the follicle shrinks, it produces finer, shorter strands. Over time, growth slows significantly.
The thinning tends to concentrate across the crown and top of the scalp, while the frontal hairline often remains relatively intact in the earlier stages. Because it develops slowly — sometimes over years or decades — it can be easy to overlook at first. Many women don’t seek guidance until density has already noticeably reduced.
Androgenic alopecia is considered a chronic condition. Hair lost through follicle miniaturisation does not typically regrow without intervention, which is why early clarity makes such a difference.
What Is Telogen Effluvium?
Telogen effluvium is entirely different in nature.
Rather than a slow thinning process driven by genetics, it is a sudden and widespread shedding triggered by a specific event — illness, surgery, significant emotional stress, hormonal change, nutritional deficiency or childbirth.
Hair grows in cycles. The anagen phase is the active growth phase and can last several years. The catagen phase is a short transitional period. The telogen phase is the resting and shedding stage, lasting a few months before new growth begins.
When the body experiences significant stress, a large number of hairs can shift prematurely into the telogen phase at the same time. The shedding often becomes noticeable two to four months after the triggering event, which is why many women struggle to connect the hair loss with its cause.
Unlike androgenic alopecia, telogen effluvium typically presents as uniform shedding across the scalp. The hairline usually remains intact. It can feel dramatic — hair in the shower, on the pillow, caught in a brush — but in most cases, it is temporary. Once the underlying cause is addressed, the growth cycle gradually restores itself.
The Key Differences
Androgenic alopecia develops gradually and is driven by genetic and hormonal factors. It most commonly affects the crown and top of the scalp and is considered a chronic condition in which lost hair does not typically regrow without intervention.
Telogen effluvium appears suddenly following a trigger. It causes diffuse shedding across the entire scalp and is usually reversible once the underlying cause has resolved.
It is also possible for both to occur at the same time. A woman with underlying androgenic alopecia may experience a telogen effluvium episode that accelerates the visible thinning significantly. This overlap is one of the reasons professional assessment can be so valuable.
How Long Does Regrowth Take After Telogen Effluvium?
There is no universal timeline.
For many women, shedding begins to stabilise within three to six months once the triggering event has resolved. Visible regrowth typically follows in the months after that. Age, health, nutrition and the nature of the original trigger all influence recovery.
During this period, reducing additional stress on the hair — such as tight styling, chemical processing or overuse of heat — can support recovery. Some women choose to use a cosmetic hair solution while regrowth occurs, not as a permanent measure, but as a bridge that allows life to continue without constant self-consciousness.

Frequently Asked Questions
Can you have androgenic alopecia and telogen effluvium at the same time?
Yes — and it happens more often than most women realise.
A woman with underlying androgenic alopecia can experience a telogen effluvium episode triggered by stress, illness, surgery or hormonal change. The sudden shedding makes the thinning appear to accelerate dramatically. It can feel as though everything changed overnight.
When the two overlap, it becomes understandably confusing. The pattern looks different. The timeline feels unpredictable. And the emotional impact is often heavier.
The important thing to understand is that they are two separate processes happening at the same time — and they require different approaches. Treating one without acknowledging the other rarely produces clarity or the best result.
How do I know which type of hair loss I have?
The pattern and timing tell you a great deal.
Androgenic alopecia develops gradually. You may notice the crown thinning slowly over years. Density reduces subtly at first. The hairline often remains relatively intact in the early stages.
Telogen effluvium, by contrast, tends to feel sudden. Shedding increases noticeably, often two to four months after a physical or emotional event. The thinning is usually diffuse rather than concentrated in one area.
A dermatologist can confirm a diagnosis medically. In a private consultation at Frankie Hair Toppers Sydney, we look at the pattern, density and your timeline to determine what cosmetic solution will genuinely support you now — not what might have worked twelve months ago.
Will my hair grow back after telogen effluvium?
In most cases, yes.
Telogen effluvium is typically temporary. Once the underlying trigger has resolved, the hair growth cycle gradually stabilises. Shedding often begins to settle within a few months, with regrowth following over time.
The exact timeline varies. Age, overall health, nutrition and the nature of the original trigger all play a role. If shedding continues beyond six months without improvement, a medical review is advisable to rule out other contributing factors.
What matters most during this period is reducing additional stress on the hair — and on yourself.
Is androgenic alopecia reversible?
Androgenic alopecia is considered a long-term condition. Hair that has been lost through follicle miniaturisation does not typically regrow without medical treatment.
That said, progression can often be slowed. And the appearance of thinning can be significantly improved.
Many women with androgenic alopecia choose a premium human hair topper or lace wig to restore density and confidence while managing the condition long term. It is not about pretending it is not happening. It is about choosing a solution that allows you to move forward without constantly thinking about your hair.
The earlier you seek guidance, the more options remain available.
Can stress cause permanent hair loss?
Stress-related shedding — telogen effluvium — is not usually permanent.
However, ongoing, unresolved stress can trigger repeated shedding cycles. Over time, that repetition may contribute to reduced overall density, particularly if there is underlying androgenic alopecia present.
If stress is a recurring factor for you, addressing it at its source is as important as any cosmetic solution. Hair reflects what is happening internally. Supporting both makes the greatest difference.
