Troubleshooting – Hints & Tips…
To get the best out of your eyelash extension adhesive/lash glue:
- We recommend making a note of the date you opened your glue, so you know when to re-order
- Apply a sticker with the date the glue was opened & stick it on the glue bottle
- Use a Jade Stone & Glue Dots rather than a Glue Ring
- Why not try a Lash Tile with Jade Stone included, keeping your lashes in order
- Replenish your lash adhesive approximately every 5-10 minutes, depending on the humidity
- Replenishing your glue frequently will ensure great workability & less waste
- We recommend using a hygrometer in your room or salon to measure the correct temperature/humidity
- Shake eyelash adhesive/glue well before use; sometimes the pigment can separate
- Make sure your lashes are all prepped & cleaned using our Foaming Brow & Lash Wash before the eyelash extension application
- Ensure you have applied the correct lash curl, weight & length
- Apply the eyelash extensions 0.5 to 1mm away from the lash line
- Finally, do NOT apply eyelash extensions any longer than a 3rd to 1/2 longer than the natural lashes
For BEST results, we recommend following our lash-prepping & lash-bonding routine;

Master Lash is my second go-to Lash Adhesive if my clients find FAST LASH a little strong. This adhesive still offers great lash retention just a little slower set speed.
