Most people spot hair thinning at the crown in a photograph taken from behind. Or under a bright bathroom light, rather than in the mirror. It creeps up, so it can go unremarked for a year. By the time you start looking at clinic treatments for hair thinning at the crown, three injectable options keep coming up: PRP, exosomes and polynucleotides.
None of the three cures anything, and a clinic telling you otherwise is overselling. PRP has been around longest and uses a sample of your own blood. Exosome and polynucleotide treatments arrived later. Both run as a course, and people often pick them as an alternative to PRP, or after a PRP course that fell short. They suit different people at different stages. So this article compares them rather than crowning a winner.
Crown hair loss, or shedding all over?
This distinction matters more than the hunt for a single best treatment. Hair thinning at the crown behaves differently from hair that came out in handfuls after an illness, a pregnancy or a stressful year. A parting that has quietly widened belongs in the first group. Sudden shedding usually has a cause worth identifying first, and often worth a word with your GP before anyone injects anything.
Timing matters too. These treatments aim at hair that is still there but weakening. Hair thinning at the crown that you catch early is a better starting point than a patch that has been bare for years. Once a follicle has gone that long, no injectable course brings it back. We would say so at the consultation rather than sell you a course that cannot deliver.
What is PRP, and why is it still the default?
PRP for thinning hair starts with a small sample of your own blood. We process it on site and inject the plasma portion into the scalp. The material comes from you, so nothing foreign goes in, and that reassures a lot of people. The clinic runs it as a course of sessions rather than a one-off.
We usually start with three or four sessions about a month apart, then maintenance visits a few times a year. Plans vary, so ask for the number before you start. Progress is slow and undramatic. Most people who respond notice the shedding settling first, long before anything looks thicker. Photographs of the crown at the start beat memory when you judge results months later. Take them, even if you would rather not.
Where do exosomes come in?
Exosome hair treatment is the newer option and skips the blood sample. That is the practical difference most people care about. It runs as a course rather than a one-off, in much the same way.
It comes up in conversation for two reasons. Some people cannot have blood drawn, or would rather not. Others have finished a PRP course and want to try something different.
Worth being straight about the evidence. Clinics have used PRP for well over a decade, and it carries much the largest research base of the three. The findings in it are mixed rather than emphatic. Exosome and polynucleotide treatments are newer, and the published evidence behind them is thinner. That does not make them ineffective. It makes them less proven, and the two are not the same thing. Anyone quoting you a precise regrowth percentage is inventing it.
And polynucleotides?
Polynucleotide treatment for the scalp is the third option, again a course of injections over several weeks. Like exosomes, it needs no blood sample.
People often ask which of the two newer treatments is better. That question has no clean answer, and we are suspicious of anyone who gives one. In practice it comes down to a few things. What your scalp looks like now, what you have already tried, and how many appointments you can realistically commit to. Cost matters too, judged across a full course rather than per session. Our prices page lists the current figures so you can do that sum properly.
How do they compare on the things people actually ask about?
- Blood sample needed. PRP yes, exosomes no, polynucleotides no.
- Appointment length. PRP takes longer. We have to draw and process the sample first.
- How quickly you would know. Months rather than weeks, for any of them.
- Track record. PRP has the longest history in clinics. The other two are newer.
- Where they go. All three go into the scalp. We cover the crown, the parting and the temples in one visit.
Treating hair thinning at the crown: what to expect
A course, not an appointment. Slow change that photographs catch before the mirror does. That goes double for the crown, because you cannot see it without help. A maintenance plan afterwards, because stopping altogether tends to drift you back towards where you started. And a real chance that you are one of the people who responds very little. Better to hear that before you commit than after session four.
Scalp treatments also work better as part of a plan than on their own. If nobody has looked for an underlying cause, or a medication or deficiency sits in the picture, that deserves attention alongside anything we do in the clinic.
Choosing a treatment for crown hair loss
A consultation starts with a look at the scalp. Then your history, and an honest read on what stage things are at. Sometimes that conversation ends with a recommendation for one of these three. Sometimes it ends with us pointing you to your GP first, or suggesting you hold off because the timing is wrong.
If hair thinning at the crown has been on your mind for a while, book your free consultation. We can work out which of the three fits your situation. For the wider picture, our hair loss treatment page covers what the clinic offers.
