The follicles were still there. They just were not doing much.

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

She came to us in October 2025. She is 48, and what she had noticed was her parting getting wider. Not patches, not a receding hairline, just steadily less hair where there used to be more.

Her overall scalp score came back at 66 out of 100. Against the 74,848 women aged 40 to 49 the scanner had on record, she ranked 65,275th. The average for her age group is about 75.

The breakdown is where this one gets interesting, and it is not what you would expect:

Look at the bottom row. Her follicle density was exactly average. She had as many follicles in the areas we measured as any woman her age.

What she did not have was output. Hair quantity at 58 against an average of 75 is a big shortfall, and it was happening from a normal number of follicles. In plain terms, the machinery was still there and it had gone quiet.

That is a better position to start from than the reverse. You cannot bring back a follicle that has gone, but a follicle that has stopped producing has somewhere to go.

One note on the panel above. That detailed breakdown comes from the full scan we run at the first appointment. What we track from then on is the overall score and the photographs.

Chapter two: what we did

She had three sessions of exosome therapy between October and December 2025. That is the fewest of any case study on this site.

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

Ten weeks later, on 11 December, her overall score had gone from 67.9 to 75.9. A rise of 8.06 points, which is roughly double the margin we treat as measurement noise.

Her scans are the clearest pair of matched improvements in our records. Both the front and the crown moved in the same direction, which is not something we can say about every patient.

This pair is about calibre rather than count. In October the hairs are fine, pale and wispy. In December they are thicker and darker. Those are largely the same follicles, producing better hair.

The crown shows the same shift.

And what it looks like without a microscope

The parting is the thing she came in about, and it is the thing that changed. It reads narrower and the scalp shows through less.

One caveat on this pair, because we would rather say it than have you wonder. The second photograph is dated 11 December, the same day as her second scan. The first is from the start of her course but we do not have an exact date recorded against it, so we have not put one on it. The scan figures either side of it are precisely dated.

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 8.06 points is about double that, and both of her scan pairs move the same way, which makes it harder to explain as a measurement artefact.

What this does and does not tell you

Ten weeks is a short window, and three sessions is a short course. This is an early result, not a finished one, and we do not know from this record where it settled afterwards.

Her starting position was also more favourable than it looked. A normal follicle count with poor output is not the same problem as a scalp that has lost follicles, and it does not necessarily respond the same way. Two people with the same overall score can be in quite different situations underneath it, which is the entire reason we scan before we treat.

Nobody can look at her numbers and tell you what yours would be.

Frequently asked questions

Is three sessions enough?

It was enough to produce a measurable change in her case, but she is one person and her starting position was unusually favourable. There is no fixed number that suits everyone. We would rather review as we go, using your own follow-up scans, than sell you a package up front.

What does it mean if my follicle density is normal?

Broadly, that the follicles are still present in the areas measured even though the hair has thinned. That is generally a more workable starting point than low density, because the aim is to get existing follicles producing better hair rather than to replace ones that have gone. It is not a guarantee of anything, but it is one of the things we look at when talking through what is realistic for you.

How soon would I see a difference?

She showed a clear change at ten weeks, which is at the quick end. Another patient in our records had gained too little to measure at his ten-week scan and ended up with a larger change than hers by eight months. Early scans are not very predictive in either direction, and we will say so rather than reading too much into your first follow-up.

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.

Are these results typical?

Hers is above average. Across the 37 patients we have complete before and after scans for, the typical improvement was around 7 points. Five 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.

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. Where we do publish them, we obscure the face.
