Hair Loss Progression Estimator

Why this tool is deliberately general, not individually predictive

No calculator can tell you exactly how your specific hair loss will progress — individual variation in genetics, hormone sensitivity, and overall health is simply too large for that kind of precision to be honest. What this tool offers instead is a realistic, population-level pattern: what tends to happen, broadly, at each stage and treatment status, based on how genetic pattern hair loss is generally understood to progress (see our Norwood scale guide and complete diagnosis guide for the underlying mechanism).

Why untreated genetic hair loss tends to keep progressing

Unlike temporary shedding conditions that resolve on their own, genetic pattern hair loss is driven by an ongoing hormonal process (DHT acting on susceptible follicles — see our DHT explainer) that doesn't stop on its own. This is the key distinction from causes like telogen effluvium, and it's why "it might just resolve by itself" isn't a reasonable expectation once a genuine genetic pattern is established, even though the pace of progression varies hugely between individuals.

Why treatment changes the picture so significantly

Consistent treatment doesn't just slow a bad outcome — for many people, it meaningfully changes the entire trajectory, shifting the realistic expectation from "steadily worse" to "stable, with some improvement." This is exactly why dermatologists consistently emphasise earlier treatment over waiting — the difference between the treated and untreated projections in this tool is the single most important reason early action matters, more than any other single piece of information on this site.

What to do with either projection

If your projection shows likely continued progression, that's not a reason for panic — it's useful information to act on. See our treatment comparison guide to understand your realistic options at your current stage. If you're already treating and the projection shows stabilisation, that's genuinely good news worth staying consistent for — see our consistency tracker to help maintain that routine long enough to see it through.

Frequently asked questions

Q: Is this based on real clinical data?
A: It reflects generally understood patterns of how genetic hair loss and its treatment are documented to progress, simplified into an illustrative projection — not a dataset specific to you, and not a substitute for a clinical assessment.

Q: What if I'm already at an advanced stage — is it too late for treatment to help?
A: Treatment can still be worthwhile at advanced stages, often alongside a transplant to protect both transplanted and remaining native hair — see our transplant guide for what that combination typically looks like.

Q: Can I re-run this after starting treatment to see an updated outlook?
A: Yes — simply toggle the treatment answer and re-calculate to compare the treated versus untreated projection for your current stage directly.
