Do semi permanent lash extensions damage the natural lashes?

Posted on June 26, 2018 at 11:15 AM

This is a question I get asked on a regular basis by clients and students alike. The correct answer is both yes and no! This is because there are many things that can go wrong with a semi permanent lash treatment if it is not carried out in the correct way. And let's be clear, we are talking about the kind of lash extensions that are applied 1:1, not clusters or party lashes. Proper semi permanent lashes are applied with one individual lash extension to one natural lash. So what is it about this treatment that can cause damage?

1. Using too much adhesive.

This is a really common mistake among new lash artists, as they tend to think that more adhesive equals longer lasting lash extensions. Yes, the extensions will last longer but only because they are stuck to 2 or 3 natural lashes (or more) per lash extension. When a tech uses too much adhesive it takes longer to dry, meaning that the lash technician has to hold the isolation for much, much longer. Most techs won't take the time to hold the isolated lash for the full time it needs to dry so instead let go and move onto the next lash. This means that the natural lashes around the extension stick to the still-wet adhesive and end up clumped together.

When lashes are stuck together it causes discomfort and damage for the client. They may not notice it at first but once the lashes start to grow they may get a bruised, uncomfortable feeling on the lash line. This is caused by the lashes that are growing dragging out the lashes that are stuck to them, resulting in premature loss of lashes and bald patches.

2. Not isolating the natural lashes correctly.

When the natural lashes are not isolated correctly during the application of the extensions, the same thing happens as when you use too much adhesive. If there is more than one lash stuck to an extension, this can cause pain and discomfort, and eventually premature loss of lashes and bald patches.

Correct isolation means applying one extension to only one natural lash.

3. Applying lash extensions that are too heavy.

This is something I see a lot. I regularly have clients coming to me with damaged lashes after going to someone who has applied thick, long lashes on top of their fine, short natural ones. For a semi-permanent lash treatment a tech should never use heavier than a 0.15 thickness, or go more than 1/3 of the natural lash length. Clients with very fine lashes would be better suited to no more than a 0.12 thickness, or 0.15 thickness in flat or cashmere lashes (as these weigh less than a traditional lash extension).

Applying anything heavier will result in premature loss of the lashes, so go easy on them! 

If a client wants something fuller, they would be better suited to having Russian Volume Lashes. This way they get the fullness without the damage as RV lashes are much, much finer.

So the verdict is, if lashes are performed using the mistakes above then yes, they are damaging

However, if the lash tech was to use minimal adhesive, isolate the natural lashes correctly, and apply extensions that will not add excess weight to the natural lashes, then the answer is NO, semi permanent lash extensions are NOT damaging to the natural lashes.
