Retention DUO - SAVE 30%


All item prices are final and inclusive of sales taxes where applicable.



We've put together our ultimate Retention DUO containing two of the BEST eyelash products on the market and an absolute must-have in every professional lash extension kit! 

Maximise your retention, keep your clients happy and save 30% compared to buying each product separately!

  • Retention & Speed Booster due to its alkaline pH, Booster gently opens the hair cuticles without damaging the natural lashes, enabling the glue to grab onto the cuticles and hold better, improving your retention. After applying Booster, natural lashes become “magnetic”, meaning you don't need to hold the extension on the natural lash for a while to help it “grip” - so your treatment time improves significantly.

  • Superbonder Sealant instantly polymerises the glue, without shock curing! It locks in the fumes from the adhesive reducing irritation and sensitivity. It also adds elasticity to the adhesive, ensuring the bonds don't break as easily, resulting in better retention. Additionally, because the bonds have been sealed, the lashes are instantly safe to get wet!

How to use



How to Use as Lash Prep:

  • Use after completing your Lash Prep routine to gently lift the hair cuticles, giving the glue more surface area to bond with
  • Apply a drop to a micro brush or lip applicator wand and dab off the excess
  • Apply to the lashes, focusing on the glue bonding area
  • allow to dry on the lashes, and proceed with your treatment

How to Use to Prevent Fan Closure

  • Booster can also be used to prevent Volume Lash Fans from closing after placement
  • Apply a drop to a micro brush or lip applicator wand and dab off the excess
  • Run the brush along the lashes on the strip. Allow the Booster to dry before you begin to dip the lashes into the glue
  • If your fans begin closing again during your lash set, simply reapply Booster to the strip and allow it to dry before proceeding
  • Do NOT use Booster on the strips of Easy Fan Lashes, as it will interrupt the glue that holds the layers together

Superbonder Lash Sealant

  • When you have finished applying lashes and have checked for stickies in your completed set, apply a drop of Superbonder to a micro brush or lip applicator wand and dab along the glue bonds, instantly curing them
  • Use a Mini Cooli lash fan to blow the Superbonder dry, and then brush through the lashes before revealing them to your client
