We recommend renewing your adhesive (whether it is opened or unopened within 6 weeks).

Having some problems with lash extension retention? Go through our troubleshooting process below:

• Adjust the level of humidity and/or temperature in the room to the recommended levels.
• Ensure you are working with an adhesive that suits your speed and technique.
• Check your adhesive bottle is still in date.
• Ensure you have shaken your adhesive for the recommended time, and the ingredients are mixed correctly.
• Provide your clients with an Aftercare Kit to ensure they are aware of the correct aftercare instructions.
• Make sure you are working on clean lashes. Remove any makeup, oils, or residue with the Cleanser Pads, and thoroughly cleanse the lashes using the Purified Sensitive Cleanser. You could also try using LashNeutral to neutralise the pH surface levels.
• Check the client consultation form, for changes in medication or possible pregnancy.
• Check the lash extension is properly adhered at the base, hold the lash in place and allow for curing time.
• Apply the correct length of extension. You can add an extension that is shorter than the natural lash or up to 3mm longer.
• Look at the position of your light. Lash lights let out heat so if they are positioned too close to the adhesive source, this can have an effect too.
