Receding or Maturing Hairline? Check It Feature by Feature
is my hairline receding or maturing
A maturing hairline and early pattern loss look similar in a mirror and behave completely differently over time. This does not tell you which one you have — nothing typed into a web page can do that. It takes the features our guides use to tell them apart, asks which ones you can actually see, and shows you the split, with the sentence behind every line.
Answer what you can above. Skipping a question is fine — an unanswered feature is simply left out of the count, which is more useful than a guess.
This one is for a dermatologist, not for a checklist
You ticked something that sits outside the receding-versus-maturing question. Patches, scalp symptoms, smooth scarred skin and sudden rapid loss are all reasons our guides give for having a scalp examined rather than watched, because they raise conditions that behave nothing like pattern loss. Here is the line behind what you ticked:
Patchy hair loss (suggests alopecia areata or other conditions)Signs of balding · DL01
Hair loss accompanied by scalp symptoms (itching, burning, scaling)Signs of balding · DL01
You have scalp pain, itching, or scarring (requires immediate evaluation)Androgenetic alopecia · C01
Rapid or sudden hair loss (not typical of pattern baldness)Signs of balding · DL01
Under 18: this comparison is not built for you
Both guides set their self-assessment aside for under-18s, and our guide on the signs of balding says directly that it is not the right reading if you are under 18 and worried about normal hairline maturation. A scalp seen by a clinician is worth more than any checklist here.

More of what you can see lines up with the maturing hairline our guides describe than with early pattern loss. That is a description of features, not a conclusion about your scalp — and the two are indistinguishable in a single sitting. Time is the test: a hairline that has matured stops.
More of what you can see lines up with the features our guides associate with early androgenetic alopecia than with a maturing hairline. That is a description of features, not a conclusion about your scalp; the same list is what a dermatologist works through, with instruments that see what a bathroom mirror cannot.
The features split evenly. That is a real result rather than a failure of the tool: early on, the two genuinely look alike, and what separates them is what happens next.
Too few features answered to show a split yet. Answer what you can see and leave the rest — the count only means anything when it is built from things you have actually looked at.

Line by line
Distance moved back
Fits a maturing hairline
Under a centimetre is inside — in fact short of — the small shift our guide describes when a hairline matures.
This typically involves minor recession of 1-2 centimeters and often corresponds to Norwood Stage 2.Signs of balding · DL01
Fits a maturing hairline
That is exactly the band the guide describes for a matured hairline, and the Norwood stage it corresponds to is explicitly not called pathological.

Adult hairline with slight temporal recession; not necessarily pathologicalAndrogenetic alopecia · C01
Fits early pattern loss
Past 2 cm is past the band the guide gives for maturation, and continuing beyond the mature hairline is the first of the three things it lists as taking recession out of that category.

Does not separate the two
Left out of the count, which is the right outcome — a distance you cannot measure is not evidence. An old head-on photograph is the only reference worth using.

Movement over 6–12 months
Fits a maturing hairline
A hairline that has stopped is the definition our guide gives for maturation. This is the strongest single line in the whole comparison — provided the comparison was made against a real photo and not a memory.
Maturation stops at a stable adult hairline. Pattern baldness continues progressing.Signs of balding · DL01
Fits early pattern loss
Continuing movement is what the guide uses to separate pattern loss from maturation. Untreated, the average rate it reports is small enough to be invisible month to month and obvious across years.

Not counted — but this is the question that settles the whole thing, so the useful move today is to create the baseline you are missing.

Fine hairs at the temples
Fits early pattern loss
Thin, short hairs growing where thick ones used to is miniaturisation, which the guide calls the hallmark sign; the variation between neighbouring hairs is what a clinician measures.

Hair shaft diameter variation greater than 20% is a clinical diagnostic criterion.Signs of balding · DL01
Fits a maturing hairline
A hairline that has moved back but is still made of uniformly thick hairs is missing the hallmark feature. A matured hairline is a lower line of normal hair, not a thinner one.

Honest answer, and not counted. Hair calibre is genuinely hard to judge by eye — magnification is what settles it, and it is unusually good at it.

The crown
Fits early pattern loss
The crown is the third item on the guide’s list of things that take recession past maturation. Maturation is a hairline event; it does not reach the crown.
When recession continues beyond the mature hairline, creates a pronounced M-shape with visible scalp at the temples, or is accompanied by crown thinning, it suggests pattern baldness.Signs of balding · DL01
Increased scalp visibility—especially in a pattern (temples, crown)—suggests thinning from pattern baldness.Signs of balding · DL01
Fits a maturing hairline
Recession confined to the temples with an untouched crown leaves one of the guide’s three markers absent.

Not counted. The guide’s own method for this is a photograph from directly above under a single overhead light, which is worth doing before you answer.

Symmetry
Does not separate the two
Even recession does not separate the two: the matured hairline our guide describes and the M-shape of early pattern loss are both two-sided. Neither guide offers symmetry as a distinguishing feature, so this moves neither count.

Also not counted either way — but a clearly uneven or patchy loss is on the guide’s list of findings that belong in front of a dermatologist, because it raises conditions other than pattern loss.

Age
Does not separate the two
You are inside the window in which our guide says hairlines normally mature, which makes maturation a live possibility rather than wishful thinking. It is not a feature of the hairline in front of you, though — your age would read the same whichever of the two is happening — so it moves neither count.

Does not separate the two
You are past the window in which our guide says hairlines normally mature. That is context rather than something you can see, so it moves neither count; what the line itself has done since is the question that separates the two, and it is counted above.

Worth flagging
Separately from the count: change before 21 is on our guide’s list of reasons to get a scalp looked at rather than watch it for another year.

Worth flagging
Context for the odds, not for your scalp: pattern loss is very common by this age, which is a reason to check features rather than assume either answer.

Family history
Does not separate the two
Family history is background risk, not a feature of the hairline in front of you — it cannot tell you which of the two you are looking at today, so it moves neither count.

What actually answers this
Not the count above. Photographs, taken now and again later, in the same light and at the same angle — because the one difference that holds is that maturation stops and pattern loss does not.

How this reading is put together
7 features, each taken from one of two guides on this site. Each answer you give is matched to a single sentence in one of them, and that sentence is printed next to the reading so you can check it. Features are counted, never weighted and never summed into a score or a percentage: there is no validated instrument behind a weighting, and inventing one would make this look more precise than it is. Each answer moves the count by at most one, and no answer is read twice.
3 of the 7 — symmetry, age and family history — count for neither side by design. None of them is something you can see at your temples, and the guides do not offer them as features that tell the two apart, so the tool refuses to pretend they do — even though family history is the thing readers most expect to be decisive, and age is the thing most readers hope will settle it.
