Hair PRP with Exosomes for Thinning Hair: Inside a Wellface Treatment

Thinning hair rarely arrives overnight. Most people notice it slowly, in the width of a parting, the amount left on a pillow, or the way a hairline photographs differently than it used to. By the time it becomes obvious, the follicles have often been quietly shrinking for years. That gradual timeline is exactly why regenerative treatments like Hair PRP with exosomes have become so popular, because they work best when there is still healthy follicle activity to protect and encourage.

One of our patients, Stewart, recently spoke to me about his experience after his fourth round of treatment at Wellface. He has it roughly once every six months, and his reason is simple. He wants to maintain the density and thickness of his hair as he gets older, rather than wait for a problem to become dramatic. His verdict on the process was honest and reassuring in equal measure. There is a little discomfort during the injections, but it is mild, manageable, and in his words, worth it in the end.

That combination of maintenance thinking and a good in-clinic experience sums up what this treatment is really about. Below, I explain how it works, what a session involves, who it suits, and what you can realistically expect.

What Hair PRP with exosomes actually is

There are two components working together here, and it helps to understand each one separately before seeing why they pair so well.

PRP stands for platelet-rich plasma. It is drawn from your own blood, so it is entirely autologous, meaning nothing foreign is introduced. A small sample is taken, much like a routine blood test, then spun in a centrifuge to separate the platelet-rich portion from the rest. Platelets are far more than clotting cells. They are packed with growth factors that the body uses to signal repair and regeneration. When this concentrated plasma is injected into the scalp, those growth factors reach the hair follicles and prompt them to behave more like younger, healthier follicles, improving blood supply and encouraging the growth phase of the hair cycle.

Exosomes take that signalling further. They are tiny vesicles, essentially microscopic delivery packages, that cells naturally use to communicate with one another. The exosomes used in hair treatments are rich in growth factors, cytokines and other messaging molecules, and they carry instructions that tell follicle cells to wake up, repair and grow. Where PRP relies on the growth factors your own platelets happen to contain, exosomes deliver a highly concentrated, standardised dose of regenerative signals directly to the follicle.

Used together, the two complement each other. The PRP creates a favourable, well-supplied environment around the follicle, and the exosomes amplify the regenerative message. Research into this area is still developing, but the underlying biology, stimulating dermal papilla cells, prolonging the growth phase and reversing the miniaturisation that causes hair to become finer, is consistent across the studies I follow.

How it differs from a hair transplant

It is worth being clear about what this treatment does and does not do. Hair PRP with exosomes is non-surgical and regenerative. It works on the follicles you still have, strengthening and reviving them. It does not relocate hair or create new follicles where none remain, which is what a surgical transplant is designed to do. For someone with early to moderate thinning, or someone who wants to protect a good head of hair as they age, the regenerative route is usually the sensible first step. It carries no scarring, no incisions and no lengthy recovery.

What happens during a session at Wellface

A typical appointment is straightforward and takes around forty-five minutes to an hour, depending on the size of the area being treated. The first step is a proper consultation. I will look at your scalp, ask about how long you have noticed changes, your family history, any medications and your general health, because hair loss can have several overlapping causes and the plan should reflect that.

If PRP is part of the plan, a small amount of blood is drawn and placed in the centrifuge to prepare the plasma. While that is spinning, the scalp is cleansed and, where needed, numbing cream is applied to keep you comfortable. The prepared PRP and the exosome solution are then introduced into the thinning areas through a series of fine injections just beneath the surface of the scalp.

This is the part Stewart described as mildly uncomfortable, and he is being fair. The scalp is sensitive, and a series of small injections can sting a little, rather like the sensation people describe with mesotherapy. It is brief, it is manageable, and numbing makes a real difference. Most people find that knowing what to expect the second and third time round makes it easier still.

Afterwards you can get straight on with your day. There is no dressing, no need to hide away, and the scalp may feel slightly tender or look a touch pink for a few hours. That settles quickly.

Downtime, aftercare and looking after your results

One of the genuine advantages of this treatment is how little it disrupts normal life. Most people are back at their desk the same afternoon. The main aftercare points are sensible rather than restrictive.

I usually advise leaving the scalp alone for the rest of the day, which means avoiding washing your hair, heavy sweating, saunas, swimming pools and vigorous exercise for around twenty-four hours, so the treated area is left undisturbed while it settles. Harsh styling products and very hot water are best avoided for a day or two. Alcohol and anything that thins the blood are worth skipping immediately before and after, as they can increase the chance of minor bruising. Beyond that, there is little to think about.

Side effects are generally limited to mild tenderness, small areas of redness or the occasional tiny bruise at an injection point, all of which resolve within a day or two. Because PRP uses your own blood, the risk of a reaction to it is extremely low.

When you will see results and how long they last

This is where patience matters. Hair grows on its own biological timetable, and no injection can override that. The treatment is planting the signals for healthier growth, and the follicles then respond over the following months as they move through their natural cycle.

Most people begin to notice changes somewhere between two and three months after starting, with reduced shedding often the first sign, followed by improvements in density and in the calibre, or thickness, of individual hairs. Results tend to build with successive sessions and are usually at their best around the six-month mark of a course.

Because the treatment supports your own follicles rather than permanently changing them, the effect is not indefinite. Hair loss is a progressive, ongoing process, so maintenance keeps you ahead of it. This is exactly the approach Stewart takes. His twice-yearly appointments are not about fixing a crisis, they are about holding onto the density he already has as he gets older. For many patients, a top-up every six months or so is the rhythm that keeps things looking their best.

Who the treatment suits

Hair PRP with exosomes tends to work best for people with early to moderate thinning who still have active follicles to encourage. It is used for both men and women, and it is a common choice for age-related thinning and pattern hair loss, as well as some other non-scarring types of shedding.

It suits people who want a non-surgical option, who are comfortable committing to a short course followed by maintenance, and who have realistic expectations about the gradual, natural-looking nature of the results. It is less suitable for someone who has been completely bald in an area for many years, where there is little follicle activity left to revive, and in those cases I will always say so honestly and talk through the alternatives.

As with any medical treatment, there are situations where it is not appropriate, including certain blood disorders, active scalp infections and some other health conditions. That is why the consultation matters, and why this treatment sits within a doctor-led clinic rather than being offered casually.

Common questions about Hair PRP with exosomes

Does it hurt?

There is some discomfort during the injections, which most people describe as a mild stinging on the scalp. Numbing cream is used to keep it manageable, and, as Stewart put it, it is a brief and bearable trade for the result.

How many sessions will I need?

A typical starting course is around three to four sessions spaced a few weeks apart, which respects the natural hair growth cycle. After that, most patients move onto maintenance, often every six months, to keep protecting their density. Your exact plan depends on your scalp and how you respond, which is agreed at consultation.

Is it safe?

The PRP element uses your own blood, so it is very well tolerated, and exosome therapy has a strong safety profile with side effects that are usually limited to mild tenderness or redness. Performed by a doctor who has assessed your suitability first, it is a low-risk treatment.

Can I combine it with other hair treatments?

Often, yes. Regenerative scalp treatment can sit alongside medical approaches to hair loss, and I will advise on what makes sense for your particular pattern of thinning. Everything is decided together based on a proper assessment.

When is the best time to start?

Earlier is almost always better. The treatment relies on there being healthy follicle activity to encourage, so acting when you first notice thinning gives you far more to work with than waiting until the change is advanced.
