Allergic Reactions

The science behind allergic reactions is very important for you and for your client to fully understand.

Firstly you must understand that ALL lash extension glues (no matter what brand they are) are part of the Cyanoacrylate Family of glues. Cyanoacrylate simply is the scientific or chemical name for a family of glues, which is more commonly known as the ‘super glue family’. Part of this family is our lash glue, super glue, some carpentry glues etc. 



This family of glues follow an exact recipe. They will have different quantities of ingredients and other added ingredients/chemicals to make it into different types of this family, but the basic structure is all the same. For example some brands will have differing ‘ingredients’ to make the glue thicker or thinner or slower or faster drying times. But the basic chemical structure is exactly the same. 

Histamine is a chemical the immune system uses to help protect the body's cells against infection. The immune system is the body's natural defence against illness and infection.

If the immune system detects a harmful foreign object, such as bacteria or a virus (or our lash extension glue in this case) it will release histamine into nearby cells. The histamine causes small blood vessels to expand and the surrounding skin to swell. This is known as inflammation.



Histamine is usually a useful substance. Allergic reactions occur when your immune system mistakes a harmless substance, such as pollen, for a threat. Quiet often a client can go for years and the body never ‘detects’ that the glue is a foreign substance, so never sends any histamines to ‘fight it’. But then for some reason, one day it decides that it is actually foreign and must be fought - so will send histamine to fight it. 

Unfortunately when your body has decided that the glue is a foreign substance that needs fighting, it will remember this & do this every single time the client goes near the glue. But remember that all brands of lash extension glue have the same chemical foundation in them, so trying different brands or ‘sensitive’ glues, will not make any difference. Your client is allergic to the lash glue and will continue to be so.

If this does happen to you, it is advised that you send your client immediately to the doctor or healthcare professional. You are not a medical doctor, so should not give any advise on treatment. 

Only remove once the inflammation has gone down.

You could offer your client a lash lift and tint and some growth serums to help her get her natural lashes to SLAY!
