Measurement literacy
What a five-year projection is, and is not
A projection is arithmetic performed on a photograph. It has never met you, does not know your family, and cannot know what you will do. The useful part is not the number at the end — it is the distance between the two paths.
What it actually is
Crown returns three numbers, not one:
The current appearance reading from this photograph.
Where that appearance reading extrapolates to over five years if nothing about the situation changes. This is never higher than today's number.
The realistic upper end over the same five years with consistent care. For patterns that are early or crown-dominant this can sit above today's number; for more advanced patterns it sits between the no-change path and today.
That is the whole object. It is an extrapolation of one appearance measurement along two assumptions. Calling it a projection rather than a prediction is not legal throat-clearing — it is the accurate word for what the arithmetic is.
The four things it does not know about you
- Your history. It has one photograph. It does not know whether you have looked like this for six years or six months, and those are enormously different situations that produce the same image.
- Your family, your age, your biology. None of that is in a photograph, and Crown does not ask for it or infer it.
- What you are going to do. The "with care" path assumes consistency that may or may not happen. It is a scenario, not a plan, and Crown does not know if you will follow one.
- Whether the photograph was any good. A projection built from a photo taken under bad light carries that photo's error forward five years and compounds the confidence you place in it.
Read the gap, not the endpoint
Here is the part worth internalising. Both endpoint numbers are soft. The distance between them is the informative quantity.
A wide gap between the no-change path and the with-care path means the reading sits at a point where the two scenarios diverge substantially — the appearance measurement is somewhere that habits still have room to matter. A narrow gap means the two scenarios land in similar places, which is itself a real piece of information stated honestly rather than dressed up.
Neither number is a destination. The gap is a description of how much the scenarios differ from where you are standing. That is a legitimate thing for arithmetic on a photograph to tell you. "You will be a 61 in 2031" is not.
What Crown deliberately does not do with it
Two hard lines
Crown never specifies what "care" means. It does not name, recommend, evaluate, rank, sell or link to any product, supplement, device, clinic or procedure, and it earns nothing from any of them. The with-care path is a scenario about consistency, not an endorsement of anything in particular. What would actually be appropriate for you is a conversation for a qualified professional, and Crown deliberately stays out of it.
Crown never presents these numbers as a promise. They are illustrative extrapolations. A projection that improves is not a commitment that anything will improve, and Crown has no outcome data on you or anyone else to make such a claim from.
The projection is not a fixed thing
Worth noticing: your projection changes every time you scan. It is recomputed from the newest photograph, so it is a function of your latest image rather than a standing forecast that was issued once and is being tracked against.
This has a useful consequence. If your projection swings wildly between two scans a week apart, that is not the future being volatile — it is your photography being volatile, amplified, because an extrapolation magnifies whatever went into it.
How to use it well
A projection is a direction, not a destination
- Track your actual scores over months. That is your real data.
- Let the projection be the thing that moves when the trend moves. Its change over time is more meaningful than any single issue of it.
- Read the gap between the two paths, not either endpoint.
- Ignore any projection built on a photo you know was poor.
- Never make a decision on the strength of a projected number that you would not make on the strength of the photograph it came from.
That last line is the whole test. The projection contains no information that was not in the photograph. It has only been rearranged into a shape that feels more certain than the photograph was.
Common questions
Are hair loss predictions accurate?
A five-year figure from a photo app is an extrapolation from a single appearance reading, not a validated forecast about an individual. It has no information about your history, your family or what you will do, and it should be read as a scenario rather than an outcome.
What does Crown's five-year outlook show?
Three numbers: your score now, where it extrapolates to over five years with no change, and the realistic upper end over the same period with consistent care. It is labelled a projection throughout and is never presented as a promise.
Why does my projection change every time I scan?
Because it is recomputed from your newest photograph rather than issued once and tracked against. Large swings between scans taken close together usually reflect variation in the photographs rather than anything about the future.
What does 'with care' mean in the projection?
It is a scenario representing consistency over five years. Crown deliberately does not specify what it should consist of, does not recommend or sell any product or procedure, and earns nothing from any. What would be appropriate for you is a conversation for a qualified professional.
