Just finished your training as a lash extension artist? Congrats! Starting your journey in this field is super exciting. Of course, you want every client to leave with beautiful lashes—and the good news is, you don’t have to learn everything the hard way. Every experienced lash artist was once in your shoes, and they’ve made mistakes you can now avoid.
We’ve put together 10 helpful tips to guide you through your early days, so you can avoid common slip-ups and build good habits from the start. Let’s dive in!
1. Don’t Spend Too Long Looking for the “Perfect” Lash
When you’re just starting, it’s easy to overthink every move—especially when isolating lashes. You might find yourself spending too much time trying to pick the “perfect” one. But the truth is, all lashes will need extensions, so don’t over-focus on one.
Pro tip: Start with the smallest, trickiest lashes first (like the baby lashes), and save the easier ones for last. That way, when you’re getting a bit tired near the end, the rest will feel easier to manage.
2. Learn to Place Eye Patches the Right Way
Getting the eye patches placed properly takes a little practice. If they’re too close to the eye, they can cause irritation or even bruising. They should never touch the waterline.
Pro tip: Place the patch at the inner corner first, then gently press it along the rest of the eye. This helps make sure it’s smooth and secure.
3. Always Use a Lash Map
A lash map helps you plan where each lash extension will go. Without a map, it’s easy to lose track and end up with uneven lashes. It’s also a great way to learn how to work with different layers of natural lashes.
Pro tip: Ask your client to open their eyes for a second so you can mark the center point. When their eyes are closed, it’s harder to tell where the center is.
4. Use the Right Amount of Glue
Too little glue, and the lashes won’t stay on. Too much, and the extensions might weigh down the natural lashes. You want to use just enough to hold without overdoing it.
Pro tip: Don’t dip the extension straight in. Try scooping it gently into the glue. If you see a small bead of adhesive, you’re good to go.
5. Never Skip the Pre-Treatment
Even if your client shows up with clean lashes, always follow your full pre-treatment routine. Skipping this step can make lashes fall out faster.
Pro tip: Use lash shampoo or protein wipes to clean the eye area, then go in with a primer. Even if they didn’t wear makeup, there might still be oils or dust on their lashes.
6. Watch the Direction of the Lashes
Getting the lashes to point in the right direction is one of the trickier parts of lash application. The corners should fan out naturally, like the rays of a sunrise. If the lashes go in different directions, the final look can seem messy.
Pro tip: Use a small mirror under the lashes to check their direction while your client’s eyes are still closed.
7. Avoid Stickies
Stickies happen when two or more lashes get glued together. It’s a common mistake, especially for beginners, but it can be fixed. Stickies usually happen if the glue hasn’t dried properly before the next lash is added.
Pro tip: At the end of every appointment, spend at least 10 minutes checking for stickies with your tweezers. Gently separate any lashes that are stuck together.
8. Choose the Right Style for Each Client
Not every lash style suits every client. Even if someone asks for a cat-eye look, it might not match their face shape, eye size, or natural lash growth.
Pro tip: Don’t be afraid to recommend a style that suits them better. And remember—not every client needs thick or heavy lashes. Save the bold looks for special occasions.
9. Talk to Your Client and Keep a Client Card
Always have a short chat before the appointment to understand what your client wants and what will work best. This also helps you manage expectations and make sure everyone’s on the same page.
Pro tip: Keep a client card for everyone. Write down what style, curl, and length you used. Update this at least once a year.
10. Don’t Place Extensions Too Close to the Eyelid
If the extension is too close to the eyelid, it can cause irritation. If it’s too far, it won’t last long or may look odd. You’ll get the hang of the right distance with time.
Pro tip: Aim for a gap of about 0.5 to 1 millimeter from the skin. When in doubt, place it a little further away rather than too close.
Final Thoughts
Learning to apply lash extensions takes time and patience, but every day is a step forward. Stick with these beginner tips, keep practicing, and you’ll improve with every set you do.
