43,011th out of 43,605. Then this.

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 one started further back than anybody else in it.

Chapter one: what the first scan found

She came to us in January 2025. She is 60, and the thinning had been going on long enough that she had stopped expecting anything to change it.

Her overall scalp score came back at 52 out of 100. The scanner compares that against everyone it has scanned in the same age band and sex, which for her was 43,605 women aged 60 to 69. She ranked 43,011th.

That is the bottom 1.4 per cent, and it is the lowest starting score of anyone we have written up. The average for women her age is about 71.

The thickness of her individual hairs was almost normal. What had gone was the follicle density: 39 against an average of 69, the largest single shortfall in any of our case studies.

Put plainly, the hairs she still had were reasonable hairs. There were just far fewer follicles producing them than there should have been.

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 six sessions of exosome therapy between January and June 2025.

She took no hair medication alongside it. No dutasteride, no hair concentrate injections, no scalp botox.

Chapter three: what changed, and why we will not give you one number

Her second scan, on 26 June, has been analysed twice by the scanner from the same set of photographs. One analysis puts her at 73.5. The other puts her at 72.5.

So her improvement is either 13.3 points or 12.3 points, from an unchanged starting figure of 60.2. Same photographs, same dates, two different answers a point apart.

We could have picked the higher one. It would have made her our single best result and nobody would have known. We have shown you both because the gap between them is the honest size of what this machine can tell you, and because a clinic that only ever quotes its higher number is not one you should trust with anything else it says.

Either way she moved from the bottom 2 per cent of women her age to somewhere near the middle, over five months, and either way it is a bigger change than the scanner’s own uncertainty by a factor of three.

The crown, January and June

Her follicle density was the number that stood out, so the crown is where you can see what that actually meant.

In January you can count the hairs in the frame. Most of what you are looking at is scalp. By June the same patch is covered.

We do not have clinic photographs covering her treatment period, only ones taken months afterwards, so there is no head-and-shoulders pair on this page. The scans cover the five months and the photographs do not, and we would rather show you the one that does.

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, then produces a single score out of 100 for the overall condition of the scalp and hair.

It is not a perfect instrument. Her record is the clearest illustration of that on this whole site: the same photographs, analysed twice, a point apart. Across our records we have seen that gap reach 4 points, which is why we treat anything under about 4 as too small to call a real change.

Her change is three times that whichever analysis you use. The uncertainty is real and it is also much smaller than the result.

What this does and does not tell you

Starting very low is not the same as being beyond help, and this page is the clearest example of that we have. But it does not work the other way round either. A low score does not predict a big improvement, and we have patients who started low and moved very little.

Hair loss has a lot of causes, and what works for one person may do very little for another. Age, how long it has been going on, the underlying reason for it and general health all make a difference. Nobody can look at her 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, including when the answer is that we cannot yet tell.

Frequently asked questions

Why does the same scan give two different scores?

The scanner works out its score by analysing the photographs it takes, and running that analysis again on the same images can produce a slightly different answer. On her record the two came out a point apart. Across our records we have seen the gap reach 4 points. It is a limitation of the instrument, not a sign that something went wrong, and it is the reason we ignore small changes rather than celebrating them.

Is a low starting score a good thing, then?

No, and we would not want anyone reading it that way. There is more room to move when you start low, but starting low also means more has already been lost. We have patients who began with low scores and improved very little. Her result shows what is possible, not what is likely.

Am I too far gone for this?

That is not something anyone can answer from a photograph or over the phone. It is what the first scan is for. She was in the bottom 2 per cent for her age and still responded, so a low number on its own does not rule anything out. If we think treatment is unlikely to help you, we will say so at the consultation rather than take your money.

Why are there no photographs of her hair?

We took clinical photographs of her, but the ones we still have on file are from months after this treatment period rather than during it. Showing those next to a January scan would be comparing two different things. The scanner images on this page cover the actual five months, so those are what we have used.

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.

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.
