Twelve reasons to decline, or to wait
A refusal list. Twelve circumstances in which the reasonable answer to an exosome treatment offer is no, or not yet, each with what it would take to turn it into a yes.

Most decision guides tell you how to choose well. This one lists the circumstances in which the correct decision is not to proceed, or not to proceed yet. Any single item here is enough to pause on, and several of them are enough to walk away from regardless of how the rest of the offer looks.
None of these is a judgement about the treatment as a category. Each is a statement about the specific offer in front of you, and most of them can be resolved by the provider supplying something they should already have.
How to use this list
A refusal list works differently from a checklist of good signs, because good signs can be manufactured and absences cannot. Each item below is either true of the offer in front of you or it is not, and most of them are settled by a single question with a factual answer.
Three of them, marked as hard stops, are reasons not to proceed at all with that provider. The rest are reasons to wait until something has been supplied or clarified. Waiting costs nothing in a category where nothing is urgent.
The twelve
| No | The circumstance | What would resolve it |
|---|---|---|
| 01 | The product cannot be named, or the manufacturer will not be stated. HARD STOP | Nothing. A product that cannot be named cannot be checked by anyone |
| 02 | An outcome is guaranteed, or a specific percentage improvement is promised. HARD STOP | Nothing. The claim cannot be supported and should not have been made |
| 03 | You are pressed to decide today, or a price expires when you leave. HARD STOP | Nothing on the day. A price held for a week turns it into an ordinary offer |
| 04 | You cannot find out whether anything will be injected | A direct yes or no, before the appointment rather than in the chair |
| 05 | The person administering it is not named, or their registration is not given | A name and a register you can check yourself |
| 06 | No study design can be described for your indication | A named design and where it was published, even if the design is weak |
| 07 | The price is a single figure covering a paired treatment as well | An itemised price, including what the paired treatment costs on its own |
| 08 | There is no written plan for what happens if there is a reaction | A written plan naming a person and an out of hours route |
| 09 | Consent is presented as a form to sign on the day, with no time to read it | The consent document sent in advance, read away from the clinic |
| 10 | Your hair loss or skin concern has not been diagnosed by anyone | An assessment first. A treatment chosen before a diagnosis is a treatment chosen blind |
| 11 | A licensed option for your condition has never been discussed | A conversation with a prescriber about what is licensed for what you have |
| 12 | You are being asked to commit to a multi session course before session one | A single session, or a course you can stop, with the terms in writing |
The three hard stops, and why
The product cannot be named. If a clinic will not tell you what the product is and who makes it, there is nothing you or anybody else can check. Regulatory status, composition, storage requirements and the manufacturer's own instructions for use all depend on knowing what it is. A refusal to name it is not commercial confidentiality, because the person receiving it is entitled to know what is being put into them.
A guarantee is offered. Outcomes in this category cannot be guaranteed, and a provider who guarantees one is either not aware of that or is willing to say things that are not supportable. Both are disqualifying, and a claim that cannot be substantiated is also a matter for the Advertising Standards Authority.
Pressure to decide on the day. A discount that expires when you leave the building is a technique, not an offer. Nothing in this category is time critical, and no clinical decision improves under a deadline set by the seller. A provider confident in the offer will hold the price for a week.
Turning a not yet into a yes
Most items on the list are informational rather than final. They describe an offer that has not yet been made properly, and they resolve when the provider supplies something they should have had ready: a product name, a named practitioner and their registration, a written plan for complications, an itemised price, or a straight answer about what evidence exists.
Asking for those things is neither rude nor unusual, and the reaction to being asked carries information of its own. A provider who supplies them without friction has demonstrated something about how they will behave if a problem arises later, which is the only part of this that is difficult to assess in advance.
If you get to the end of the list with no item triggered, you have not established that the treatment works. You have established that the offer is being made properly, which is a different and more modest thing. What the evidence does and does not support is covered on the study design page and on the evidence page.
What this page does not cover
This is a general reference for assessing an offer. It is not medical advice, it is not a contraindication list, and it cannot tell you whether a treatment is suitable for you, which requires somebody who can examine you and take a history. It names no clinic, practitioner, product, manufacturer or price, and it makes no claim about any specific provider. It does not cover the biology or manufacture of extracellular vesicles, which belong to Exosomal Therapy. Where a treatment has already gone wrong, the routes for raising it are with the provider first, then the relevant professional regulator or the Care Quality Commission, and complaint handling in cosmetic treatment is the territory of Clinic Insider rather than this site.
Common questions
Is it unreasonable to ask a clinic for a product name
No. It is the most basic question available, and the person receiving a treatment is entitled to know what is being used. Without it, regulatory status, composition and the manufacturer's own instructions cannot be checked by anybody.
Why is a guaranteed result a reason to walk away
Because outcomes in this category cannot be guaranteed, so the guarantee is either uninformed or unsupportable. A claim that cannot be substantiated is also a matter for the Advertising Standards Authority.
What is wrong with a discount that expires today
Nothing in this category is time critical, so a deadline exists to prevent you thinking about it. A provider confident in the offer will hold the price long enough for you to read the consent form away from the building.
Should I be committing to a course of sessions up front
Not before the first one, and not without written terms covering what happens if you stop. A course purchased in advance transfers the risk of it not suiting you onto you, entirely.
What if my hair loss has never been diagnosed
Then any treatment choice is being made blind, because different types of hair loss behave differently and some resolve without intervention. Diagnosis comes first, and it usually changes the conversation.
If none of the twelve applies, does that mean it works
No. It means the offer is being made properly, which is about the provider rather than the treatment. What the evidence supports is a separate question and is covered elsewhere on this site.
Where do I complain if something goes wrong
With the provider first, then the relevant professional regulator for the person who treated you, and the Care Quality Commission where it applies. Keep dates, names and the product details you were given.
