How Long do Eyelash Extensions Last?

Are you interested in getting eyelash extensions for the first time? One thing that you need to know is how long you can expect your extensions to last.

There are a number of factors that determine how long your extensions will stay on, but the general average is about 2-4 weeks.

In this post, we'll discuss what causes lashes to last and how they interact with natural lashes.

The Type of Extension and How Long They Last

As we wrote about in other posts, there are 2 types of lashes. There is natural mink fibers made from real hair from the mink animal. Then there is synthetic lashes which are divided into two subsets of faux mink lashes and silk lashes.

The natural mink lashes will be heavier and not perfectly curved so it will put a lot of strain on your actual eyelashes when glued on. The strain of the heavy natural fibers can cause your real lashes to fall sooner than expected so you can hope for about 2-3 weeks with these depending on how strong your actual lashes are.

The synthetic lashes of faux mink and silk are extremely lightweight so they won't be as much a burden on your real lashes. Because they aren't as heavy as natural mink fibers, you can expect the synthetics to last about 3-4 weeks, again depending on how strong your actual lashes are.

The Length of the Eyelash Extension

As we just mentioned previously, the strength of your actual real lashes play a big part in how long extensions last. If you have short, weak lashes, you don't want extensions too long or they will strain your real lashes.

The general idea is your extensions shouldn't be more than twice the length of your real lashes. If you follow this rule, you can expect to get about 3-4 weeks out of your extensions.

The Hair Cycle Stages

Our hair is constantly falling out and growing back. That is a natural process of the living human body. Just like with any hair on your body, your lashes also fall out and grow back.

There are three phases of this life cycle to know:

Anagen: This is the primary growth phase.
Catagen: This is the transitioning phase.
Telogen: This is the resting phase.

It's not really feasible to tell which phase we are at in a given time, but understand that this can affect the duration of your lashes.

For example, if your hair happens to be in the Catagen phase, it means your hair has stopped growing temporarily. Your lashes might last a while like this. Conversely, if you're in the Telogen phase, your hair is beginning to shed so your lashes might fall off sooner than expected.


There are so many factors that determine how long lash extensions will last. Consequently, it comes down to how well your extensions work with your body. If you have naturally strong lashes, you'll probably see your extensions last for 3-4 weeks.

The concluded average is about 2-4 weeks for most people. So don't be surprised if yours last longer or shorter than expected.
