lash porosity and lash PRIMING 101

Priming your clients can go one way or another, it'll either result in amazing retention or they'll all fall off quickly. In this blog, find out why you shouldn't prime all of your clients and learn why, in depth, but quickly.


First, let's get into what our eyelashes look like- up close and personal!


What is lash porosity? It's the ability of the natural lash to absorb moisture and retain it.


Porous natural lashes are liable to dryness and are more able to absorb products. (The more porous the natural lash, the better retention will be.)


Un-porous (silky/oily) results in less moisture, thus meaning worse retention than porous.


The more moisture that can be absorbed, the better the adhesive will bond to the natural lash.

what does priming actually do?

Prepares the surface of the natural lash before application and provides an optimal PH level, which is needed for good retention.


Also strips the natural lashes of natural oils and residue.

What does cleansing do?

Removes dirt, make up, bacteria and any imperfections.


It also helps prevent inflammation.

when to prime

When lash porosity is low (oily clients) priming will open the cuticles and be susceptible for better retention.


Priming on all clients can potentially do more harm than good!


Primer optimises the pH of the NL, so if you're using this on non-oily lashes this can cause poor retention as the pH levels will be off for bonding.


It helps achieve a faster attachment time by dissolving any natural oil or makeup residue on the natural lashes and opening the cuticles.

when to cleanse

You should always cleanse your clients lashes before their appointment, this will remove dirt, make up and bacteria off the NL removing any potential barriers for good retention.


Clients should also be cleansing their lashes daily, regardless of their lifestyle. Even if they don't go to the gym, sweat, wear make up etc, bacteria will still make it's way to their extensions.


Cleansing your lashes obviously cleans them, reducing the chance of inflammation e.g blepharitis

how do i know if my client has oily lashes?

Simply, if they have oily skin- they're more than likely going to have oily lashes. Having o skin is NOT a contraindication (a symptom or condition that makes a treatment risky) to lashes. You'll just need to prime and ensure they're following the correct aftercare inbetween infills.
