Hair PRP for Thinning and Hair Loss: How Your Own Blood Can Rebuild Density

Hair loss rarely announces itself. It creeps in at the temples, thins across the crown, or shows up first in the way you start parting or styling your hair to hide what is happening underneath. By the time most people book an appointment, they have already spent months quietly watching the mirror and wondering whether anything can actually be done.

One of the treatments I return to again and again for thinning hair at Wellface is PRP, short for platelet-rich plasma. It uses a small sample of your own blood, spun down to concentrate the parts that drive healing and repair, then delivered back into the scalp to wake up tired follicles. No donor material, no synthetic actives, nothing borrowed from anyone else. Just your own biology, put to work where it is needed.

A recent patient captured the point beautifully. A fit and healthy man in his twenties with male pattern baldness running through his family, he had already undergone a hair transplant abroad. His donor area at the back looked perfect, but the front stayed stubbornly thin, and there was a visible mismatch between his natural hair, the thinning zone and the transplanted line. He had done PRP before with good results, and he came back for maintenance. That word, maintenance, is the heart of what PRP does well, and it is worth understanding why.

What PRP actually is and how it works on the scalp

PRP stands for platelet-rich plasma. The process starts with a simple blood draw, much like the one you would have for a routine blood test. That sample goes into a centrifuge, which spins at speed and separates the blood into layers by weight. The red blood cells and white blood cells settle at the bottom. What we want sits above them: the plasma, rich in platelets.

Platelets are best known for helping blood to clot, but they are also tiny reservoirs of growth factors. These are signalling proteins with names like platelet-derived growth factor, vascular endothelial growth factor and insulin-like growth factor. In plain terms, they are the messengers your body uses to trigger repair and to build new blood supply. When I draw the plasma off, I keep the part of the blood that carries the healing cascade and leave behind the red and white cells that do not contribute to that process.

Injected into the scalp in small amounts across the thinning areas, this concentrated plasma does a few things at once. It improves blood flow to the hair follicles, it nudges dormant follicles out of their resting phase and back into active growth, and it supports the surrounding tissue so that hair grows in thicker and more resilient. The exact mechanism is still being studied, but the working principle is well established: give the follicles a concentrated dose of your own growth factors, and many of them respond.

It is worth being honest about one limit. PRP works on follicles that are still alive, even if they are miniaturised and producing fine, wispy hairs. It cannot conjure hair from skin that has been completely bald for years, because there is nothing there to stimulate. That is why the treatment suits early to moderate thinning so well, and why it pairs so naturally with a hair transplant rather than competing with one.

What a hair PRP session at Wellface involves

The appointment itself is more straightforward than most people expect. It usually runs somewhere between forty-five minutes and an hour and a half from start to finish, and the vast majority of that time is preparation rather than the injections.

First, I take a small sample of blood from your arm. That tube goes straight into the centrifuge while I get the scalp ready, often with a numbing cream to keep the injections comfortable. Once the plasma has separated, I draw it into a syringe and inject it in tiny quantities across the areas of thinning, working methodically so the growth factors are spread evenly through the zones that need them. Because the volumes at each point are so small, the treatment covers a lot of ground with many little injections rather than a few large ones.

Most people describe the sensation as a series of quick pinches or a tingling across the scalp. It is very tolerable, and because the plasma comes from your own body there is no risk of an allergic reaction to a foreign substance. You walk out the same day and get on with things. Some tenderness, mild redness or a feeling of tightness across the scalp is normal for a day or so, and it settles quickly.

How the treatment plan usually runs

PRP is not a single-visit fix, and it was never designed to be. The standard approach is a loading phase followed by maintenance. In the loading phase, most patients have a course of three to four sessions spaced roughly four to six weeks apart. That spacing is deliberate. It mirrors the natural hair growth cycle and gives newly stimulated follicles time to respond before the next round of growth factors arrives.

After the initial course, results are maintained with top-up sessions, often every six to twelve months depending on how your scalp responds and how aggressive the underlying thinning is. This is exactly what my returning patient was doing. He had built his foundation with earlier treatments, seen a good response, and come back to keep the follicles supported so the gains did not quietly slip away.

Who tends to benefit most

The best candidates are people in the early to middle stages of thinning who still have living follicles to work with. That includes men with early male pattern hair loss, women noticing diffuse thinning across the crown or a widening part, and anyone whose hair has lost density and body without going fully bald in the affected areas.

PRP is also a genuinely useful partner to hair transplant surgery. A transplant relocates follicles into thinning zones, but it does nothing for the native hair around them, and that surrounding hair often keeps thinning on its own timeline. That is precisely the mismatch my patient described: a crisp transplanted line at the front, perfect hair at the back, and a band of fine, thinning native hair caught in between. PRP works on that native hair, helping to blend the result and support the follicles the surgery never touched.

There are situations where PRP is not the right call, or where I would want a fuller conversation first. Completely bald areas will not respond, because there is nothing left to stimulate. People with certain blood disorders, active scalp infections or particular medical conditions may not be suitable, and some medications can affect how well the plasma performs. This is why every course starts with a proper consultation and, where needed, a look at the wider picture of why the hair is thinning in the first place.

What results look like and when to expect them

Hair grows slowly, and PRP works with that biology rather than against it, so patience is part of the deal. You will not walk out with thicker hair that afternoon. What tends to happen is more gradual and, for that reason, more natural-looking.

In the first weeks, some patients notice less shedding, which is often the earliest sign that the follicles are responding. Visible improvements in thickness and density usually start to show around the three to six month mark, as the stimulated follicles produce stronger hairs and the growth cycle shifts in your favour. Because the effect builds session on session, the picture generally keeps improving across a full course rather than peaking early and fading.

The results are not permanent, and I would never promise that they are. The growth factors do their work and then diminish over time, and the underlying tendency towards thinning does not disappear. Left entirely alone, treated follicles can gradually drift back towards their previous state. That is the whole reason maintenance matters, and why my patient framed his visit the way he did. As I put it to him, it is a great positive start, and there is still more that can be done from here.

Combining PRP with other approaches

PRP often performs best as part of a broader plan rather than in isolation. For hormonally driven hair loss, prescription medications that tackle the root cause can work alongside PRP, which stimulates the follicles directly. Microneedling is another natural partner, since it encourages growth factor release in its own right and helps the plasma reach the follicles. And for people who have had or are considering a transplant, PRP supports both the transplanted and the surrounding hair. I will talk through which combination makes sense for your particular pattern of thinning.

Common questions about hair PRP

Is PRP painful?

Most people find it very manageable. I usually apply a numbing cream to the scalp beforehand, and the injections are small and quick. The most common description is a brief pinching or tingling sensation. Because the treatment uses your own blood, there is no risk of reacting to a foreign product.

How many sessions will I need?

A typical starting course is three to four sessions spaced about four to six weeks apart, followed by maintenance top-ups every six to twelve months. The exact plan depends on how advanced the thinning is and how your follicles respond, which is something I will assess as you go.

Can PRP regrow hair on a completely bald scalp?

No, and it is important to be clear about that. PRP stimulates follicles that are still alive but underperforming. Where an area has been fully bald for a long time, the follicles are no longer there to respond, and a surgical option like a transplant is the more realistic route. PRP can then help support the surrounding hair.

Is there any downtime?

Very little. You can return to your day straight away. It is normal to have some redness, mild tenderness or a tight feeling across the scalp for a day or so. I usually suggest avoiding vigorous exercise, swimming and harsh hair products for the first day to let the scalp settle.

Does PRP work for women as well as men?

Yes. Female thinning, which often shows as reduced density across the crown or a widening part rather than a receding hairline, responds well to PRP when the follicles are still active. The same loading and maintenance principles apply.

Talk to me about your hair

Thinning hair is one of those concerns that feels much bigger in private than people let on, and the earlier it is addressed, the more there is to work with. If you have noticed less density, more shedding or a hairline that no longer sits where it used to, a consultation is the sensible first step. I will look at what is actually driving the change, tell you honestly whether PRP is likely to help, and build a plan around your hair rather than a template.

You will find us at our clinics in Cobham, Esher and Wimbledon. Book a consultation with me and we can talk through PRP, how it might fit alongside anything you have already tried, and what a realistic result looks like for you.
