Which lash adhesive dries the fastest?

Our quickest-drying adhesives include Power Bond, Royal Bond, all designed to cure within 0.5–1 second when used in the correct conditions.

• Power Bond performs best at 64–72°F (18–22°C) and 50–65% humidity
• Royal Bond works well at 64–72°F and 30–80% humidity

• Keep in mind: higher humidity speeds up curing time, while lower humidity slows it down.

• These adhesives are extremely fast and are best suited for advanced lash artists. Using a glue that cures too quickly for your working speed can negatively impact retention.

How do I choose the right lash glue?

The best eyelash extension adhesive for you depends on your experience level, room conditions, and working speed.

- Beginner or intermediate artists: opt for slower adhesives like Lady Bond or Satin Bond for better control 

- Advanced artists: faster adhesives can help you work more efficiently

To choose accurately, you'll need to know:

• Your room temperature
• Your room humidity
• How quickly you place the extension after dipping into the adhesive

Using a hygrometer is highly recommended to monitor your environment and maintain consistency. For a full breakdown, check out our lash glue comparison guide or reach out to our support team at info@londonlashpro.com.

Which lash glue is best for sensitive clients?

All professional lash adhesives contain cyanoacrylate, the ingredient responsible for bonding. Most allergic reactions are triggered by adhesive fumes, not the liquid itself.

If a client has previously had an allergic reaction, it's very likely they will react again. In these cases, lash extensions are not recommended.

For clients who experience mild sensitivity (not a true allergy), you can:

• Use Superbonder at the end of the appointment to help reduce fumes
• Improve airflow with tools like an extraction fan to minimize exposure

• Always follow proper consultation procedures and never work on clients with known contraindications.

Why is my lash glue drying too slowly?

Slow curing is usually caused by low humidity or incorrect room temperature.

To speed up your adhesive:

Increase humidity levels in your workspace

Adjust room temperature to fall within your glue's recommended range

Apply Booster to the lash strip to accelerate curing

Helpful ways to increase humidity:

• Use a humidifier
• Place a damp towel near a heat source
• Lightly hydrate lashes during prep
• Work in sections to help maintain moisture

If your speed has improved over time, your adhesive may simply be too slow for your current skill level — switching to a faster glue could make a real difference in your results.

Why has my lash glue become thick or stringy?

Changes in adhesive consistency are usually caused by exposure to air, moisture, or improper storage.

To prevent this:

Store glue in a cool, dry place, away from direct sunlight

Avoid pushing dried adhesive back into the bottle

Replace glue every 4–8 weeks after opening

Always close the cap immediately after use

Never clean the nozzle with nozzle wipes

Proper care will help maintain optimal performance and retention.

Why are my volume fans closing?

If your fans close after dipping, your adhesive is likely too slow for your working speed.

To fix this:

Increase humidity and/or temperature in your workspace

Use Booster on the lash strip (never directly on natural lashes)

Also check that you're not picking up too much adhesive. Balanced conditions and the correct amount of glue are key to maintaining open, symmetrical fans.

How do I clean my glue nozzle properly?

After every use:

Wipe the nozzle with a lint-free glue wipe

Store the bottle upright

Gently squeeze out any residue before closing

When shaking manually:

Remove the cap

Cover the nozzle with a wipe to prevent clogging

Important: Never use cotton pads, tissues, or any fibrous materials. These can react with cyanoacrylate and cause heat buildup or safety risks.

What is the shelf life of lash adhesive?

Unopened: Up to 6 months from the production date

Opened: Best used within 4 weeks (maximum 8 weeks)

For sample sizes (2ml), use within 5 days of opening.

Pro tip: write the opening date directly on your bottle so you can easily track freshness.

What should I do if my glue nozzle is blocked?

If your nozzle becomes clogged:

Replace it with a spare nozzle

Use a Glue Rescue Kit if the cap is stuck

A nozzle opener tool can make replacement much easier

To avoid blockages:

Clean the nozzle after every use

Store your glue correctly

Avoid squeezing the bottle when dispensing

Why is there white residue on my glue bottle?

White residue is caused by shock polymerization, which occurs when adhesive comes into contact with moisture. To prevent this, store your glue in an airtight container, keep it away from humidity and direct sunlight, and make sure the cap is tightly sealed after each use.

Why does my glue look clear instead of black?

Adhesives must be shaken thoroughly before use. Shake for 1–2 minutes (or use a glue shaker) to ensure all ingredients are properly mixed.

Note: Crystal Bond is the only adhesive designed to remain clear. All other adhesives should appear fully black when ready to use.

How should I store lash glue correctly?

Before opening: Keep sealed in the original packaging. Storing in the refrigerator can help extend shelf life

After opening: Store at room temperature in an airtight container, away from heat, sunlight, and humidity

Always store upright. Proper storage is essential for maintaining adhesive performance.

How do I remove lash adhesive safely?

Eyelash extensions should always be removed by a trained professional. Never pull or force extensions off, as this can cause damage to the natural lashes.

For safe removal, use a professional remover such as Cream Remover or Gel Remover. Work in small sections and make sure the eyes are properly protected throughout the process.

Following correct removal techniques ensures a safe and comfortable experience for your client.
