PRP or exosomes for hair loss: how the sessions differ

TL;DR

• PRP (platelet-rich plasma) is made from a small sample of your own blood, spun in a machine in the clinic while you wait, then applied to your scalp.
• Exosome hair treatment uses a ready-made product applied to the scalp, so no blood sample is needed.
• At Revitalise Clinic in Halifax, PRP is £150 for one hour. Exosome sessions are £150, £300 or £500, and the two combined are £270.
• Nobody can promise what either will do for your hair, and the clinic does not. Evidence and regulation for exosome products are still at an early stage.
• Every hair session starts with a free 30 minute consultation, in person or by video, at a pharmacist-led clinic.

PRP and exosomes are two different hair loss sessions. PRP is made from a small sample of your own blood, prepared in the clinic while you wait. Exosomes come as a ready-made product. The sessions differ in what happens, how long they take and what they cost.

This guide explains what each one is, how a session runs at Revitalise Clinic, 4 Hopwood Lane, Halifax, and what is known about how each is regulated. It is general information about the appointments. It does not tell you what either will do for your hair, and it is not advice about your own health.

What is PRP for hair?

PRP stands for platelet-rich plasma. Plasma is the pale yellow liquid part of your blood, and platelets are tiny cells within it. PRP is made from your own blood, so nothing from another person or animal is used.

At the start of the appointment a small sample of blood is taken from your arm, in the same way as a routine blood test. The tubes go into a machine called a centrifuge, which spins them fast. This separates each tube into a yellow layer of plasma on top and red blood cells underneath. The plasma is then drawn off and applied to the agreed areas of your scalp with a fine handheld injector.

There is no single agreed way to prepare PRP. A 2020 scoping review of PRP methods found that universal standards for preparing it are still lacking, with great variety in how fast and how long the blood is spun and what is added to it. That is a fair question to ask any clinic: how do you prepare it?

What are exosomes?

Exosomes are tiny particles released by cells, far too small to see. A 2023 review of exosomes in aesthetic surgery describes them as small sacs wrapped in a membrane, which cells use to pass signals to each other. The products sold to clinics are made from different sources, including bone marrow, placental, fat and umbilical cord tissue.

For hair, exosomes come as a ready-made product that is applied to the scalp. No blood is taken. Revitalise offers three, listed in the online diary by product name:

• Mesoestetic exosomes: 45 minutes, £150.
• Purasomes HSC50+: 30 minutes, £300.
• 200 billion exosomes: one hour, £500.

The products differ in what is in them and how long the session takes. The difference is explained at the consultation, including what each product is made from.

How do PRP and exosome sessions differ?

The biggest difference is where the material comes from: your own blood for PRP, a ready-made product for exosomes.

	PRP	Exosomes
What is used	Plasma from your own blood	A ready-made product
Blood sample?	Yes, from your arm	No
Prepared in the clinic?	Yes, spun in a centrifuge while you wait	No, it arrives ready to use
Session length	1 hour	30 minutes to 1 hour, by product
Price at Revitalise	£150	£150, £300 or £500

You can also have both in one session. PRP and exosomes combined is booked as one hour and costs £270.

What happens at a hair session at Revitalise?

A hair session follows the same steps each time, with one extra step for PRP.

1. Free hair loss consultation

Every hair treatment starts with a free 30 minute consultation, in person or by video. Your practitioner looks at your scalp and asks about your hair, your general health and any medicines you take. They explain what PRP and exosome sessions involve and cost, and whether either is suitable is decided with you. You will be told if neither is.

2. Blood sample (PRP only)

For PRP, a small sample of blood is taken from your arm. You feel a sharp scratch, like any blood test. The tubes are spun while you wait.

3. Treating the scalp

The prepared plasma, or the exosome product you chose, is applied to the areas agreed at the consultation. Your practitioner tells you what is happening as it goes. The scalp can feel uncomfortable during this part, so say if you need a pause.

4. Aftercare and home

Before you leave, your practitioner explains how to look after your scalp over the next few days, including when you can wash your hair. Any advice before a session, who should not have PRP or exosomes, and any downtime are covered at your consultation before anything is given.

Who carries out hair sessions at Revitalise?

Revitalise Clinic is owned and run by Adil Mahmood, a pharmacist registered with the General Pharmaceutical Council (GPhC 2076427). Hair sessions are given by the clinic team. Mohammad Subhan Anwar Khan, a pharmacist independent prescriber (GPhC 2078837) and co-director, has clinical oversight. Sophia Shah, who has 16 years’ experience in healthcare, gives treatments under Subhan’s oversight. You can read more about the clinic and check both pharmacists on the GPhC register. Treatments are for adults 18 and over.

One patient wrote on Google:

“I had combined session of excosomes and prp after a hair transplant, very professional and great service.”

Does PRP or exosome treatment regrow hair?

Nobody can promise that, and Revitalise does not. The NHS hair loss page notes that no hair loss treatment is 100% effective. The 2023 exosome review found that clinical studies in aesthetics were limited to anecdotal reports.

What the clinic can tell you is what happens in each session, who does it, how long it takes and what it costs. At the consultation your scalp is looked at and you get an honest view on whether a session is suitable for you at all. You are never asked to commit to a course before your first session.

The NHS also suggests seeing a GP to find out what is causing your hair loss before going to a commercial hair clinic. Some hair loss has a cause a GP can look into, such as illness, stress or low iron. That is good advice, and the team may suggest it too.

How are PRP and exosome products regulated?

PRP and exosomes sit in different places, and the rules for both are still being settled.

Exosomes. In the US, the FDA consumer alert states that there are currently no FDA-approved exosome products, and that exosome products meant to treat diseases or conditions need its approval. The 2023 review says the same of the US market. If you are thinking about exosomes anywhere, ask what the product is, who makes it and what it is made from.

PRP. In England, the government consulted in 2023 on licensing non-surgical cosmetic procedures. Its consultation response, published in August 2025, shows the original proposal placed “platelet rich plasma (PRP) therapy for cosmetic purposes” in its middle-risk group. Many respondents asked for it to move to the highest-risk group. The response makes clear the regulations are still to come, so none of this is in force yet.

Whoever you choose, it is reasonable to ask:

• Are you registered with a professional body, and what is your number?
• For PRP, how is it prepared, and is the kit single use?
• For exosomes, what is the product and where does it come from?
