How to Correctly Attach Lash Extensions

2025.08.21

Every lash artist wants to achieve that perfect bond between natural lashes and extensions. But even the best consultations and the perfect design can end with premature shedding. This stressful side effect can leave any lash artist feeling frustrated and confused.

If you’re struggling with eyelash extension retention for your clients, you’re not alone. To help bring you peace of mind, our experts have put together key lash attachment and placement tips for clients.

 

Attach Lash Extensions

Attach Lashes 0.5mm Away from the Skin Along the Lash Line

Importance of Proper Distance from the Eyelid

Extensions must be placed along the natural eyelash, 0.5mm away from the skin along the lash line. This specific distance is essential to prevent any contact between adhesive and delicate eyelid skin.

Preventing Irritation and Ensuring Comfort

If the extensions are not correctly placed at the distance required, this can result in two issues: placing lashes too close can cause glue to seep into the skin, leading to pain, swelling, redness, and puffiness. Additionally, the lash can rub every time that the client opens and closes their eye. On the other hand, attaching lashes too far out leaves a visible gap where dirt and oils can become trapped underneath the lash extension.

Tools and Techniques for Measuring 0.5mm Accurately

To ensure precise placement at 0.5mm from the eyelid, lash artists often use magnifying glasses or LED lamps with adjustable focus. Fine-tipped isolation tweezers also help maintain control during attachment. Practicing on mannequins can enhance accuracy before working on clients.

Make Sure the Base of the Extension is Fully Attached

Achieving Full Bond Between Natural Lash and Extension

No matter what curl, length, the direction you use, it’s important to make sure the base of the lash extension is fully attached to the natural lash, at least 2mm. This ensures a strong bond that supports optimal retention.

Common Mistakes in Base Attachment

A frequent error occurs when extensions are placed at an incorrect angle or on bent natural lashes. If you’re not careful, you can place it at the wrong angle and the base of the natural lash can stick up. Furthermore, some natural lashes grow bent or sideways Bent eyelashes won’t give you enough bonding surface and are likely to fall off prematurely.

How Incomplete Attachment Affects Retention

Incomplete bonding leads to premature shedding because dirt and oils can become trapped underneath, weakening adhesive performance. It also increases friction when brushing through lashes or during daily activities.

The 90-Degree Rule

What is the 90-Degree Rule in Lash Application

The 90-degree rules simply mean that each eyelash extension should be placed at a 90-degree angle. This standard applies regardless of your body position or how natural lashes grow.

Benefits of Applying Extensions at a Right Angle

Attaching extensions at a right angle enhances symmetry and overall design uniformity. When the lash extension is placed at a wider angle than 90-degree on the inner corner it can cause discomfort to the customer.

Adjusting Hand Position to Maintain Correct Angle

To maintain a consistent 90-degree attachment across different eye zones (inner corner to outer), artists must adjust their wrist angle and tweezer positioning accordingly. Using ergonomic tools like curved tweezers facilitates better control for precision placement.

Can I Attach a Lash Extension from the Side?

Side Attachment vs. Top or Bottom Placement

There is no written rule in lash extension from which direction you must attach the extensions. While top attachment remains most popular due to its versatility with straight or downward lashes, bottom attachments suit upward-growing lashes well.

Side attachment offers volume benefits: The advantage of the side attachment method is that it makes the lashes fuller.

Risks and Limitations of Side Attachment

However, this method has limitations: Do not choose this method if your client has curly natural lashes it’s hard to get enough bonding surface from the side when natural lashes have strong curls.

When Side Attachment May Be Appropriate

Side attachment works best for clients with sparse or straight lashes needing added density. For layered effects, experts recommend using top attachments for upper layers and bottom attachments for lower ones: Use the top attachment method on top layersand use bottom attachment on lower layeryou have them covered in all angles!
