Before any extensions are actually applied, you will have a consultation with the therapist. At that stage, you will/should receive a patch test (see below). At the consultation, the therapist will have to go through a longish list of possible infections or medical conditions which would be ‘contra-indications’. Contra-indications are circumstances which, for medical reasons, would mean:
- you cannot have eyelash extensions at all, (or, at least, not without specific written confirmation from your doctor), or
- you can go ahead, as long as you sign an ‘informed consent form’ to confirm that you had the risks and potential effects fully explained to you and were still willing to go ahead without getting permission from your doctor.
Obviously, if you have got some specific medical problems such as a stye or inflammation of the eyelid due to bletharitis, then you can’t have treatment while that persists.
Some people have conditions like dry eye syndrome, where the tear glands produce fewer tears, and if you have that you would need to have your GPs confirmation that it is safe to have eyelash extensions. The opposite is watery eyes, where your eyes water excessively, and then you wouldn’t be able to have eyelash extensions simply because the glue wouldn’t be able to set properly.
These and other issues will be discussed during the consultation. Hopefully, there are no problems, and you can go ahead.
The patch test
Before the full set of extensions are actually applied, you will have a ‘patch test’. (It’s called that, but it doesn’t actually involve a patch.) This is a test using a small number of extensions to make sure that you won’t react allergically to the products which are going to be used – most particularly, the adhesive. If you do react adversely the test lashes can be removed immediately.
