Key facts
- Ludwig scale
- Grades female pattern hair loss I–III: diffuse thinning over the crown with the frontal hairline typically preserved
- Norwood scale
- The male pattern — I–VII, receding temples and crown loss. Grading a woman on it usually misdescribes what is happening
- Hair cycle
- Each follicle cycles through anagen (growth, lasting years), catagen (transition) and telogen (rest) — normally most scalp follicles are in anagen at any one time
- Telogen effluvium
- A synchronised shift of many follicles into telogen after a trigger — illness, childbirth, crash dieting, major stress — producing diffuse shedding on a delay of months
- Ferritin
- The body’s iron store, measured in µg/L — low ferritin is a recognised contributor to diffuse hair shedding in women and is invisible without a blood test
- Thyroid function
- Both underactive and overactive thyroid states disturb the hair cycle — screened with TSH and related tests, not by looking at the scalp
- Diffuse vs patterned
- Widening part and preserved hairline suggests pattern loss; shedding evenly from everywhere suggests a systemic cause; patches suggest something else again
Women lose hair differently
Most of what is written about hair loss — and most of what is advertised about female hair loss in Singapore — borrows its mental model from men: a retreating hairline, a thinning crown, one dominant hormonal mechanism, graded on the Norwood scale from I to VII. Female hair loss rarely looks like that. The characteristic pattern in women is diffuse: the part line widens, the ponytail slims, overall density falls across the crown — while the frontal hairline usually holds its position. That pattern has its own grading system, the Ludwig scale, running I to III.
The distinction is more than terminology. A man with a receding pattern has, statistically, a short list of likely explanations. A woman with diffuse thinning has a long one — and several of the entries on that list are general medical conditions rather than scalp conditions. Treating the scalp before working through that list means, quite literally, treating a symptom without a diagnosis.
So the honest starting point for female hair loss is not a device, a serum or a package. It is the question: which kind of loss is this, and what is driving it?
The longer cause list
Female pattern hair loss — the hormone-related, gradual, patterned form — certainly exists and is common. But sitting alongside it are causes that mimic it closely. Thyroid disturbance in either direction disrupts the hair cycle and presents, from the outside, as thinning hair. Iron deficiency — and specifically depleted ferritin, the storage form of iron — is a well-recognised contributor to diffuse shedding in women, and can be present without anaemia and without symptoms beyond the hair.
Then there is telogen effluvium, one of the most misunderstood diagnoses in this field. Each follicle cycles independently through a growth phase lasting years, a brief transition, and a resting phase, after which the hair sheds. A major physiological trigger — childbirth is the classic one, but serious illness, surgery, crash dieting and severe stress all qualify — can push a large share of follicles into the resting phase at once. The result is heavy, frightening, diffuse shedding a few months after the trigger. Post-partum shedding is this mechanism, and its most important feature is that the follicles are resting, not dead.
Add hormonal transitions such as the years around menopause, restrictive dieting, and certain medical treatments, and the picture is clear: the list of things that thin a woman's hair is long, and most of it cannot be identified by looking at a scalp.
Why blood work belongs in the assessment
This is the point of the whole page. Several of the commonest drivers of female hair loss — thyroid disturbance, depleted iron stores, and other systemic contributors — are detectable on a blood panel and on nothing else. No scalp camera sees a ferritin level. No treatment device measures thyroid function. If a clinic examines your scalp, pronounces a diagnosis and recommends a programme without anyone asking about blood work — recent results from your GP count — then the assessment has skipped the step most likely to change the answer.
The sequence I use is deliberately unexciting. History first: when the shedding started, what happened in the months before it, pregnancies, diet, medications, family pattern. Examination second: the distribution of loss, the state of the hairline, the calibre of the hairs, the scalp itself. Blood work third, where the history and examination point to it — because a diffuse shedding pattern with a suggestive history makes laboratory screening part of basic diligence, not an optional extra.
Only after those three steps does treatment selection mean anything. This is the same logic set out across our hair loss treatment guide: the therapy is chosen by the diagnosis, never the other way round.
“If nobody ordered blood work before recommending a treatment, the assessment is incomplete.”
Dr Sin YongOn diagnosing female hair loss properly
Treating the scalp without the cause is treating the symptom
Consider what happens when this order is reversed. A woman with thyroid-driven shedding is sold a course of scalp treatments: the driver continues untouched, the shedding continues, and the conclusion drawn is that her hair loss is “stubborn”. A woman with post-partum telogen effluvium — a condition in which follicles are resting, not lost — is enrolled in an intensive programme, and the recovery that was coming anyway is attributed to whatever she happened to be paying for at the time. In both cases the scalp was treated. In neither case was the patient.
None of this means scalp-directed treatment has no place for women — it has an important one, once the diagnosis supports it. Where the finding genuinely is female pattern hair loss, options are laid out on the female hair loss treatment page, and regenerative approaches such as Regenera Activa are discussed where follicles are miniaturising but still active. Where the finding is systemic, the first prescription may be written by an endocrinologist or simply be iron — and a clinic should be comfortable saying so.
Response to any treatment varies with the cause, the duration of loss and the state of the follicles, which is exactly why it is assessed individually rather than promised in advance.
Why this page has no before-and-after images
Hair loss marketing runs on photographs, so their absence here deserves a direct explanation.
Under Singapore’s Healthcare Services Act, before-and-after imagery in advertising for licensable healthcare services is prohibited. There is no consent-form or disclaimer exemption, and after-only images fall under the same rule. The prohibition binds every licensed clinic in Singapore identically — a clinic showing such photographs is not showing stronger results, only weaker compliance. What replaces the photographs here is an assessment thorough enough to find the cause, which is worth more to your hair than any image.
What determines the cost
Prices for licensable healthcare services cannot be advertised in Singapore — no figures, ranges or “from” amounts — so none appear on this page.
What cost depends on can be described: the extent of the work-up the history calls for, what the assessment and any blood results actually find, whether treatment is directed at a systemic cause, the scalp, or both, and how a plan is staged and reviewed over time. A post-partum shedding pattern needing reassurance and monitoring, and established pattern loss needing a structured programme, are entirely different pieces of work. Fees are set out in full at consultation.
The part worth saying first
Female hair loss is not the female version of male hair loss. It has its own patterns, its own grading, and a cause list long enough that skipping the diagnostic step is not efficiency — it is guesswork with a programme attached.
If your part is widening, your ponytail has slimmed, or shedding has surged after childbirth, illness or a hard year, the useful first step is an assessment that takes the whole picture seriously — history, examination and, where indicated, blood work. Dr Sin Yong — MBBS (NUS), MRCS (Edinburgh), MSc Aesthetic Medicine (London), MSc Practical Dermatology (Cardiff) — assesses female hair loss personally at Orchard Road, and will tell you plainly what is driving yours before anything is recommended for your scalp.
