Lash Like a Pro: 10 Common Mistakes Beginners Make (And How to Fix Them)

on July 05, 2025

Whether you're just starting your journey as a lash artist or experimenting at home, mastering lash extensions takes time, patience, and the right tools. Even seasoned professionals once made the same mistakes most beginners face today. But don’t worry—we’ve got your back (and your lashes). Below, we’ll walk through 10 common beginner mistakes and how to fix them, plus product recommendations from GladGirl to help you lash like a pro.

1. Skipping Proper Lash Cleansing

Issue: Failing to clean the natural lashes before application leads to poor retention. Oils, makeup, and debris prevent adhesives from bonding properly.

Fix: Use a lash-safe cleanser like GladGirl Lash Shampoo and Cleansing Brushes to prep lashes thoroughly.

2. Using Too Much Glue

Issue: More glue doesn’t mean better hold—it can actually cause clumping or slow drying.

Fix: Use GladGirl Professional Lash Adhesive with micro brushes or glue rings for precise control.

3. Incorrect Isolation

Issue: Not isolating natural lashes properly can cause lash sticking and discomfort for the client.

Fix: Practice your isolation technique with fine-tipped isolation tweezers, and be patient.

4. Poor Lash Placement

Issue: Applying lashes too close to the eyelid or too far away can lead to discomfort and premature shedding.

Fix: Lashes should be placed 0.5–1mm away from the lash line for a safe and natural look.

5. Choosing the Wrong Lash Style

Issue: Not all lashes fit every eye shape. A dramatic D curl might overwhelm hooded eyes, while J curls may look too subtle on almond eyes.

Fix: Use the GladGirl Lash Trays with a variety of curls and lengths to customize every set.

6. Ignoring Aftercare Instructions

Issue: Many clients unknowingly ruin their extensions by exposing them to steam, oil, or makeup removers.

Fix: Send clients home with an aftercare kit, including Lash Shampoo, spoolie brushes, and a printed care card.

7. Not Refilling Your Tools

Issue: Using old, dried-out glue or dull tweezers can sabotage your work.

Fix: Always replace adhesive every 4–6 weeks and keep backup application tools on hand.

8. Rushing Through the Process

Issue: Speed comes with experience. Rushing can lead to messy placement, uneven sets, and unhappy clients.

Fix: Focus on quality over speed. A beautiful, clean set is always worth the extra time.

9. Neglecting Lash Mapping

Issue: Freestyling might work for some, but mapping ensures symmetry and a flattering design.

Fix: Use GladGirl Under Eye Gel Pads and lash mapping markers to sketch out your design before you begin.

10. Not Practicing Regularly

Lashing is a skill that improves with repetition.

Fix: Practice on mannequin heads, friends, or even strip lashes to keep sharpening your technique.

• Clean lashes thoroughly before application
