Androgenetic alopecia is gradual, pattern-based hair loss driven by genetics and the hormone DHT, while telogen effluvium is sudden, all-over shedding triggered by stress, illness, or a major life event. Androgenetic alopecia tends to progress without treatment; telogen effluvium is usually temporary, resolving within three to six months once its trigger is addressed.
What Is Androgenetic Alopecia?
Androgenetic alopecia, also called male or female pattern hair loss, is one of the most common types of hair loss in Singapore, developing slowly over months and years, not overnight. It is linked to genetics and to dihydrotestosterone, or DHT: an enzyme in the scalp converts testosterone into DHT, which binds to hair follicle receptors in people with a genetic sensitivity to it, shortening the follicle’s growth cycle. [1] Over repeated cycles, this “miniaturises” the follicle, so each new hair grows thinner, shorter, and paler than the last, until some follicles stop producing visible hair altogether. [1]
In men, this usually starts as a receding hairline forming an “M” shape at the temples, alongside crown thinning; left untreated, the two areas can meet into the more advanced “U” shape often associated with typical male baldness. [1] In women, the pattern is different: instead of a receding hairline, it typically shows up as diffuse thinning across the crown and mid-scalp, with the frontal hairline generally staying intact, described in dermatology literature as the Ludwig type, graded by severity on a three-point scale. [2] Many women first notice it as a widening centre parting rather than an obvious bald patch.
Left unaddressed, androgenetic alopecia is progressive: miniaturised follicles generally do not resume normal hair production on their own, and hair loss from this pattern is considered permanent without intervention. [1] This is exactly why earlier assessment matters, since the earlier a pattern is confirmed, the more follicles are still viable to support.
The TCM Interpretation: Kidney Essence
In TCM methodology, hair is regarded as an outward expression of kidney essence, or jing, the body’s deep reserve of vital energy that also governs growth, ageing, and reproductive health. Gradual thinning that tracks with age or family history is often understood in this framework as a sign of declining kidney essence, not a purely localised scalp problem, which is one reason our consultations look at sleep, stress load, and overall constitution, not just the hairline.
What Is Telogen Effluvium?
Telogen effluvium is one of the most commonly seen causes of sudden, diffuse hair loss in Singapore, alongside androgenetic alopecia. Unlike a slow, hormone-driven process, it is a temporary disruption that pushes an unusually large number of follicles into the resting, or telogen, phase at once. Weeks later, those resting hairs shed together, which is why the loss can feel sudden even though the trigger happened earlier.
It is typically set off by a significant stressor: a high fever or infection, major surgery, a crash diet or sudden nutritional deficiency, childbirth, a medication change, or intense psychological stress. [3] Thyroid imbalances are also a recognised trigger, and because thyroid, postpartum, and medication-related shedding can point to a condition needing separate care, it’s worth taking the time to consult a doctor if shedding is significant, ongoing, or paired with other symptoms. [3]
Unlike androgenetic alopecia, telogen effluvium does not follow a pattern: shedding is diffuse and all-over, most noticeable on top of the scalp, showing up as visibly more hair in the shower drain, on a pillow, or in a hairbrush. [3] There is no receding hairline and no localised bald patch, one of the clearest ways to tell the two conditions apart.
For most people, it is reversible. Shedding usually lasts three to six months, and once the trigger has resolved, regrowth follows in a similar timeframe, with most cases fully recovering within six to eight months. [3] Because the timeline runs to months, it is worth being patient once the underlying cause is addressed, rather than assuming the shedding will continue indefinitely.
The TCM Interpretation: Blood Deficiency and Liver Qi Stagnation
TCM methodology views hair as “the surplus of blood”, so a sudden shock, physical (illness, childbirth, crash dieting) or emotional (prolonged stress), is often framed as a depletion of blood or a disruption of liver qi. Liver Qi stagnation in particular is associated with the emotional strain that frequently precedes a telogen effluvium episode, which is why our approach here leans on replenishing and calming techniques, not the follicle-stimulation focus used for androgenetic alopecia; the underlying imbalance and the treatment target differ.
Head-to-Head Comparison
| Androgenetic Alopecia | Telogen Effluvium | |
| Onset | Gradual, over months to years | Sudden, weeks after a trigger |
| Pattern of loss | Localised (hairline, crown) | Diffuse, all-over |
| Trigger | Genetics and DHT sensitivity | Stress, illness, surgery, diet, postpartum, medication change |
| Reversibility | Progressive without treatment | Usually temporary, resolves in 3–6 months |
| Gender prevalence | Affects both, pattern differs by sex | Both, often linked to a specific life event |
| TCM treatment approach | Nourish kidney essence, reduce DHT-linked imbalance | Nourish blood, ease liver Qi stagnation. |
| Expected recovery | Requires ongoing management | Natural recovery once the trigger resolves |
Self-Diagnostic Checklist: Which One Do You Have?
Likely Androgenetic Alopecia If:
- Thinning is concentrated at the crown, temples, or hairline, not spread evenly across the scalp
- A parent or grandparent had a similar pattern of hair loss
- The change has been gradual, developing over several years rather than weeks
Likely Telogen Effluvium If:
- Shedding is sudden, noticeably heavier than usual, and affects the whole scalp evenly
- You can point to a stressful event, illness, crash diet, childbirth, or medication change in the last one to three months
- There is no family history of pattern baldness and no localised bald spot
Still Unsure?
Hair loss patterns can overlap, and a telogen effluvium episode can sometimes unmask androgenetic alopecia that was already present but not yet visible. If your pattern does not clearly match either list, the most reliable next step is a proper scalp and hair analysis rather than guessing from a checklist. Book a personalised consultation with our team before starting any treatment.
How Beijing 101 Treats Each Type
Androgenetic alopecia and telogen effluvium come from different root imbalances, so treatment differs for each, and 92% of customers agree Beijing 101 provides the most effective hair treatment because every plan starts with a personalised consultation to confirm which pattern, or combination of patterns, is actually present.
For Androgenetic Alopecia
Our approach is built around a herbal protocol targeting the scalp environment linked to DHT sensitivity, alongside treatments aimed at stimulating follicle circulation and encouraging remaining growth potential. Because this is a progressive, long-term pattern, we treat it as ongoing management, with plans reviewed and adjusted as the scalp responds. Results vary from person to person, depending on how advanced the thinning is when treatment begins.
For Telogen Effluvium
Here, the emphasis shifts to blood-nourishing herbs such as dang gui (Chinese angelica root) and red dates, paired with stress-reduction techniques and scalp circulation support for follicles already moving back towards their growth phase. Suitability depends on individual health history: dang gui is generally avoided during pregnancy or alongside blood-thinning medication [4], which is why our consultants assess each customer individually instead of prescribing a standard formula to everyone.
Why Correct Diagnosis Comes First
Treating telogen effluvium as androgenetic alopecia, or the reverse, wastes time while the real cause goes unaddressed: a protocol for long-term DHT-linked thinning will not resolve a stress-triggered shedding episode, and calming, blood-nourishing support will not slow a genuinely progressive pattern. Every consultation therefore begins with identifying which type is actually present.
Frequently Asked Questions
What is androgenetic alopecia?
Androgenetic alopecia is a common cause of hair thinning in Singapore, and the location is the giveaway: a receding hairline with crown thinning in men and all-over crown thinning with an intact hairline in women. It develops gradually from an inherited DHT sensitivity and does not resolve without treatment.
What is telogen effluvium?
Telogen effluvium is a temporary shedding phase, not permanent: a trigger such as illness, surgery, childbirth, or a medication change pushes many follicles into their resting phase together, with the loss visible weeks later. Most cases settle within three to six months once addressed.
Can telogen effluvium turn into androgenetic alopecia?
No: the two have different causes, so one does not turn into the other. A shedding episode can make an already-developing case of androgenetic alopecia easier to notice, since it draws attention to areas that were already thinning. If shedding has not settled after a few months, get the scalp rechecked instead of waiting it out.
What is the best treatment for alopecia in Singapore?
There is no single best treatment for alopecia in Singapore, since androgenetic alopecia and telogen effluvium respond to different approaches, and even two people with the same type can need different plans depending on severity and health history. At Beijing 101, we build a personalised treatment plan following a proper consultation, rather than applying one protocol to every customer.
How does TCM treat alopecia?
Beijing 101 develops its hair loss treatments using TCM methodology, which frames hair health as connected to the body’s broader internal balance, particularly kidney essence, blood, and qi. In practice, this means herbal formulations, scalp treatments, and stress-focused techniques chosen according to which imbalance is contributing to a customer’s hair loss, rather than treating every case of thinning the same way.
The Right Diagnosis Changes Everything
Knowing which type of hair loss you have is what makes any treatment plan worth starting.
Androgenetic alopecia and telogen effluvium can look similar in the mirror but come from entirely different causes, and mistaking one for the other means treating the wrong problem. If you are unsure which type you are experiencing, or whether both are at play, book a personalised hair and scalp consultation with Beijing 101 for a clear answer and a treatment plan built around your specific pattern, not a generic one.
