Lash extensions are a semi-permanent beauty treatment that enhance the length, curl, fullness, and thickness of natural eyelashes. The lashes are applied one by one to the natural lash line with a surgical-grade adhesive, which lasts for the length of the natural lash cycle (typically six to eight weeks) until they naturally shed. Lash extensions are popular among celebrities and everyday women who desire long, luscious lashes without having to use mascara or other temporary cosmetic solutions.

If you’re interested in becoming a lash extension technician, also known as a lash artist, there are a few things you should know. This guide will give you an overview of what is required to become a lash extension technician, including the necessary training, certification, and business start-up considerations.

What are Lash Extensions?

Lash extensions are a semi-permanent way to achieve longer, fuller lashes. The lashes are applied one by one to your natural lashes to give you the look of having mascara on without the worry of it smudging or running. Lash extensions can last anywhere from 2-4 weeks with proper care and are relatively low maintenance.

Classic Lashes

Classic lashes are single lash extensions applied to one natural lash at a time. They are semi-permanent, lasting 6-8 weeks with proper care, and can be applied to achieve a number of different looks. If you’re new to lash extensions, classic lashes are a great place to start.

Volume Lashes

Volume lashes, also called Russian volume or multi-lash, are very trendy right now. They give the illusion of a thicker, fuller lash line. A full set of volume lashes can take up to 2 hours to apply because each natural lash gets 3-5 individual synthetic lashes applied to it.

The Lash Extension Process

If you are thinking about becoming a lash extension technician, there are a few things you should know about the process. First, you will need to choose the type of lash extensions you want to use. There are synthetic, mink, and silk lashes, and each type has its own set of benefits. Once you have chosen the type of lashes, you will need to measure and cut them to the length that you want.


The consultation is where you will discuss the look your client is hoping to achieve. It’s important to find out what kind of lash style they are looking for and if they have any lash concerns. You will also want to find out if your client has any sensitivities or allergies. During the consultation, you will want to:

-Discuss the different lash extension styles and find out which style your client is hoping to achieve.
– Ask if your client has any lash concerns, such as Lash shedding, loss of length, etc.
– Determine if your client has any sensitivities or allergies.
– Choose the right type of lash extension based on your client’s natural lashes.

Patch Test

A patch test is a quick and easy way to ensure that you are not allergic to the lash extension adhesive. The test should be performed at least 48 hours before the application. It involves applying a small amount of adhesive to the inside of your wrist and observing the area for any signs of irritation, redness, or swelling. If you experience any adverse reaction, do not proceed with the lash extension application.

Preparing the Lashes

Before anything else, your natural lashes must be cleansed of all oils and makeup. Next, a primer is applied to the lash line to cleanse and disinfect the lashes and to help the bond between natural lash and extension last longer. Once the primer dries, it’s time to start lashing!


Applying lash extensions is a delicate process that requires a steady hand, good eyesight, and a lot of patience. The lash extension technician will start by carefully measuring the length and width of the natural lashes and selecting the appropriate size of lash extension. Once the lashes are selected, the technician will then use a thin layer of glue to attach the lash extension to the natural lash. The extensions are applied one at a time and can take anywhere from 45 minutes to 2 hours to apply a full set of lashes.


As a lash extension technician, you will be responsible for providing your clients with aftercare instructions. It is important to educate your clients on how to take care of their lashes so that they can maintain the look and feel of their extensions. Aftercare instructions may vary depending on the material used for the lash extensions, but there are some general tips that you can share with your clients.

Here are some aftercare tips to share with your clients:

– Avoid getting the lashes wet for 24 hours after the lash application.
– Gently brush the lash extensions with a clean mascara brush daily.
– Be careful when using oil-based products near the lash line, as this can break down the adhesive bond and cause the lashes to fall out prematurely.
– Do not use waterproof mascara on the lash extensions, as this can be difficult to remove and can cause breakage.
– Schedule touch-up appointments every 2-4 weeks to maintain the look of full, luscious lashes!


There are several ways to remove lash extensions, but the most common is with a special adhesive remover. This can be applied with a brush or cotton swab, and will dissolve the bond between the extension and your natural lash. Once the majority of the adhesive has been removed, the extensions will simply fall off.

If you go to a professional to have your lash extensions removed, they will likely use an ultrasonic device to break up the bond before carefully removing each individual extension. This is generally a painless process, but it can be slightly uncomfortable if you’re sensitive to sound.


As you can see, there are many steps involved in becoming a lash extension technician.

You will need to complete a training program, obtain a license, and insurance. You will also need to purchase the right supplies and equipment.

With the right training and supplies, you can become a lash extension technician and provide this beauty service to clients.
