Why Do Eyelash Extensions Stick Together? Causes and Solutions

Eyelash extensions should be light, airy, and beautifully separated. But sometimes a set suddenly feels heavy, the hairs start crisscrossing, or multiple lashes clump together. This not only looks messy, but it can also feel painful and cause damage to your natural lashes.

In the lash world, lashes that are stuck together are also known as "stickies". In this article, we explain why eyelash extensions clump together, what the risks are, and how to effectively resolve and prevent this.

1. Why Do Eyelash Extensions Clump? The 5 Main Causes

Lashes sticking together can be caused by application errors, but also by daily habits:

A. Improper Isolation During Application ("Stickies")

Eyelash extensions must be placed with extreme precision, one hair (or cluster) at a time.

• The problem: If a lash stylist does not isolate carefully, a neighboring natural hair or a young baby lash can accidentally get stuck to the glue of the applied extension.
• Consequence: Because hairs grow at different speeds, the faster-growing hair pulls on the slower-growing hair. This causes a tugging, painful sensation at the eyelid margin.

B. Too Much Lash Glue

• The problem: When too much glue is used, it takes longer to cure and excess glue can spill over onto surrounding lashes. The base of the lashes then becomes hard, stiff, and thick.

C. Using Mascara on Eyelash Extensions

• The problem: Mascara is designed to thicken and coat hairs. On extensions, mascara causes the soft, open fans to immediately close up and clump together into stiff clusters that are almost impossible to brush out.

D. Buildup of Sebum, Makeup, and Dirt

• The problem: If lashes are not washed regularly, natural skin oils, dead skin cells, and dust mix together around the lash base. This forms a sticky residue that causes lashes to stick to each other.

E. Sleeping Wrong and Not Brushing

• The problem: Friction against a cotton pillow can cause lashes to twist and become tangled at night. If they are not brushed out afterward, they will become permanently knotted.

2. Why Are Clumped Lashes Harmful?

Eyelash extensions sticking together is more than just a cosmetic problem:

• Damage to the lash follicles: If two natural hairs are stuck together while one grows and the other does not, the shorter hair is pulled out prematurely. This can permanently damage the lash follicle.
• Irritated eyelids: Clumps at the base trap bacteria and sebum, which can lead to itching, redness, and inflammation (such as blepharitis).
• Feeling of tightness: A set should feel weightless. Do you feel a tugging or stinging sensation when you blink? Then you are almost certainly dealing with "stickies".

3. How Do You Fix Clumped Lashes?

Depending on the cause, you should address the problem as follows:

[Step 1: Wash Thoroughly] ➔ [Step 2: Dry Completely] ➔ [Step 3: Gently Separate with Spoolie]

Solution A: Tangling due to Sleep or Makeup Residue

1. Wash your lashes: Use a special oil-free lash shampoo (lash foam) and a soft brush to gently loosen all sticky oils and dirt residue.
2. Rinse and dry: Rinse thoroughly with lukewarm water and pat dry carefully.
3. Brush gently: Wait until the lashes are 100% dry. Place a clean lash brush (spoolie) on top of the lashes, slowly roll the brush downward, and gently comb them from base to tip.

Solution B: Clumps due to Incorrectly Applied Glue ("Stickies")

• NEVER pull on them yourself! Never try to pull apart lashes that are stuck together with glue using your fingers or tweezers. You are guaranteed to pull out your own natural lashes in the process.
• Go back to a professional: A certified stylist can safely and painlessly separate the stuck lashes using two professional tweezers or a mild remover.
