1. Shake vigorously for 45–60 seconds before use.
2. Dispense a fresh adhesive drop onto your preferred glue surface.
3. Dip approximately 2–3 mm of the lash base into a minimal amount of adhesive.
4. Attach the extension approximately 0.5 mm away from the lash line.
5. Adjust your placement speed according to your room humidity.

Pro Tip: If you want Hook-Up Adhesive to cure faster, use a humidifier to increase the humidity in your lash room. Higher humidity helps accelerate the curing process, so always monitor your room conditions and adjust gradually.

• Using the same working speed at every humidity level → Slow down slightly in drier conditions and work faster as humidity increases.
• Picking up too much adhesive → Hook-Up has a thin viscosity, so only a small amount is necessary.
• Working in a room that is too warm → Keep your environment close to the recommended 18–22°C range for more predictable performance.
• Skipping proper shaking → Shake thoroughly before dispensing to ensure the formula is evenly mixed.
• Continuing with an aging glue drop → Replace the drop once its texture begins to change.

Why does the same Hook-Up Adhesive feel faster on some days than others?

Cyanoacrylate adhesive reacts with moisture in the air, so changes in humidity can noticeably affect curing speed. Even when using the same bottle and technique, a more humid day may make your adhesive behave faster than it did in drier conditions.

Is thin-viscosity adhesive better for lash extensions?

Not necessarily—it depends on the artist's technique and preference. Thin adhesive can create very clean attachment points and requires only a small amount of product, but artists need good dipping control to avoid picking up too much or too little adhesive.

Can I use Hook-Up for Promade fans?

Yes. Hook-Up can be used with Classic, Volume, and Promade lash extensions. Its thin consistency works well when only a controlled amount of adhesive is needed at the fan base.

Why do my lashes stick together after placement?

Stickies usually occur when adjacent natural lashes come into contact before the adhesive has fully cured. Maintain clean isolation and periodically check completed sections throughout the appointment, especially when working in lower humidity where Hook-Up cures more slowly.

Why can retention still vary even when I am using the correct adhesive?

Adhesive is only one part of retention. Natural-lash preparation, attachment area, adhesive freshness, room conditions, application technique, the client's natural lash cycle, and aftercare can all affect how long extensions remain attached. Curacoro specifically notes that environment and careful attachment technique are important factors in retention.
