Let’s say, you have just applied some gorgeous lash extensions on a client, to see that the same client comes back in just a few hours. The reason? The lashes have become brittle, dry and there’s some type of white residue on the lash line! If you have been in a similar situation, then you’ve encountered what’s known as Shock Polymerization, also referred to as ‘blooming’. But many beginner lash technicians don’t have any experience with this phenomenon. In today’s article, we want to break down and explain what Shock Polymerization is, why it occurs and share a few tips to avoid this event from happening.
What Is Shock Polymerization?
First things first, let’s describe what is Shock Polymerization. Even though this word may sound confusing at first, once you know the science behind it, it becomes very clear and simple. Shock Polymerization is basically a chemical reaction that takes place when the cyanoacrylate glue, or the lash extensions adhesive, cures and dries too quickly. This process then causes the black glue to frost and turn white around the lash line. While ‘blooming’ isn’t as scary as it may sound, it may cause some problems for lash extensions.
Why Does It Occur?
Now that we know the definition, let’s discuss why the chemical reaction occurs. Shock Polymerization happens when the cyanoacrylate glue is exposed to too much moisture, making it dry way too quickly. Lash pros know that a bit of moisture is needed for the liquid lash glue to turn solid. But excess moisture can actually cause micro shatters and make the glue connection between a natural lash and a lash extension weak. Meaning, the glue turns brittle, and the connection won’t be as flexible as we initially wanted it to be.
How To Avoid It
The next point is how to avoid ‘blooming’. As we’ve mentioned, Shock Polymerization happens because of too much moisture. Therefore, the first reasonable tip is to ensure that the lash line is completely dry. If your client’s eyes get watery, make sure you dry the lashes as soon as possible using blotting paper. Another great tip is to start attaching the lash extensions to the outer corners of the lash line. Why? Well, as the hours go by, eyes can get irritated under the bright lights. By beginning on the outer corner, you’ll save yourself some time for the glue to cure properly without too much moisture. These are the main ways you can avoid Shock Polymerization or ‘blooming’.
