She started in the bottom 2 per cent. Here’s what happened next.

Not a study. Our own patients.

Almost everything written about exosome therapy for hair loss comes from somewhere else. A manufacturer’s trial, a small study in another country, a summary of a summary. Useful, but it is not us, and it is not you.

So we started keeping our own record. Every patient who has the treatment is scanned at the start and scanned again as they go, on the same machine, in the same clinic. We now have complete before and after scan data for 37 people.

This is one of their stories, told in the order it happened.

Chapter one: what the first scan found

This visitor came to us in December 2024. She is 49. She had thinning across the front and sides of her scalp, the hairline had pulled back above both temples, and the area over each ear had thinned to the point where the scalp showed through.

None of that is unusual. A lot of women live with it for years before asking anyone. It is easy to hide under a certain hairstyle and much harder to ignore in the mirror.

What was unusual is what the scanner said. Her overall scalp score came back at 55 out of 100. The scanner compares that against everyone else it has ever scanned in the same age band and sex, which at the time was 74,848 women aged 40 to 49. She ranked 73,573rd out of 74,848.

That puts her in the bottom 2 per cent. The average score for women her age is about 75. She was twenty points below it.

The scan also breaks the scalp down into separate measures. Three of them matter most for thinning, and all three were well below average:

This is the part of the appointment people find hardest, and we would rather show it to you than talk around it. You cannot decide what to do about a problem you have not measured.

One note on the table above. That detailed breakdown is produced by the full scan we run at the first appointment. What we track from then on is the overall score and the photographs, which is what the rest of this page shows.

Chapter two: what we did

She had seven sessions of exosome therapy between December 2024 and June 2025.

She took no hair medication alongside it. No dutasteride, no hair concentrate injections, no scalp botox. That matters when you read what follows, because it means the change came from one treatment rather than a combination of several.

Chapter three: what changed

By June her overall score had gone from 58.3 to 71.1, a rise of 12.8 points. These are the scanner images from her file, the front of her scalp in December and again in June.

You do not need to be a clinician to read that one. In December there are a handful of hairs with bare scalp between them. In June the same patch is covered in fine new growth.

The crown tells a quieter version of the same story.

And what it looks like without a microscope

The change is clearest along the temple and above the ear. In March there is a wide band of visible scalp running from the hairline back towards the crown. By June that band has filled in, and the hairline sits lower and looks less ragged at the edge.

One thing to be straight about: this pair covers March to June, not the full six months. Her earliest clinic photographs are not in our current records. The scanner images above do cover the whole period.

How we measured it, and where the measurement is soft

We use a scalp scanner in clinic called Becon. It takes magnified photographs at set points around the head, at the front, the crown, the back and both sides, then produces a single score out of 100 for the overall condition of the scalp and hair.

It is not a perfect instrument, and we would rather say so than pretend otherwise. When we went back through our own records, the same set of photographs re-analysed on different occasions came back up to 4 points apart. So we treat anything under about 4 points as too small to call a real change. That is the shaded band on the chart above.

Her 12.8 points is comfortably clear of it. Her result is real, not a rounding error.

What this does and does not tell you

Hair loss has a lot of causes, and what works for one person may do very little for another. Age, how long the thinning has been going on, the underlying reason for it and general health all make a difference. Nobody can look at someone elses numbers and tell you what yours would be.

What we can say is that we measure, we keep the records, and we will tell you honestly what we are seeing in your own scans as we go.

Frequently asked questions

What is the scalp score, and can I see mine?

It is a number out of 100 that our scanner produces from magnified photographs of your scalp taken at several points around your head. Higher is better. You can absolutely see yours. We scan at your first appointment and again as you go, and we will show you the comparison rather than just telling you it looks better.

How many sessions will I need?

She had seven over roughly six months, but there is no fixed number that suits everyone. It depends on how much thinning there is, how your scalp responds to the first few sessions and what we see on your follow-up scans. We would rather review as we go than sell you a package up front. At your consultation we will give you a realistic idea of what your own course might look like.

How soon would I see a difference?

Hair grows slowly, so this is not a quick fix. The photographs on this page show a visible change between March and June, which is roughly three to six months into her treatment. Most people should expect to wait several months before there is anything obvious in the mirror, and the scan will usually pick up a change before your eye does.

Are these results typical?

No, and we would not want to suggest otherwise. Her improvement sits right at the top of our records, among the largest of the 37 patients we have complete before and after scans for. We say “among” deliberately: one other patient scores either side of her depending on which of two re-analyses of the same photographs you take, so we would not claim a clear first place. The typical improvement across that group was around 7 points. Five people showed a change too small to count as real, and one got slightly worse. The chart on this page shows all of them.

Is this available on the NHS?

No. Exosome therapy for hair loss is a private treatment and is not available through the NHS. The NHS does provide support for some causes of hair loss, particularly where it is linked to an underlying medical condition, so it is worth speaking to your GP if you have not already. You do not need a GP referral to come and see us.

Do I need a referral from my GP?

No, you can book directly with us. That said, if your hair loss has come on suddenly, or alongside other symptoms such as fatigue or changes to your skin and nails, it is sensible to see your GP as well. Some causes of hair loss are worth investigating with blood tests, and we will say so if we think that applies to you.

Will my photographs be used?

Only if you say yes in writing. We take clinical photographs so that you and we can see what is changing over time. They stay in your record unless you give us specific written permission to use them elsewhere, and you can withdraw that permission at any time.
