Lash Kit Essentials: Glues & Liquids
In our Part 1 of the Lash Kit Essentials mini-series, we talked you through four of our all-time bestsellers from our eyelash extension and lash accessory collections. Today, we would like to give you a little information on the glues and other liquids that consistently make it into the kits of Lash Technicians all over the world.
Lash Extension Glue
Lady Bond lash adhesive has been part of the London Lash glue collection from the very beginning—it is one of our original lash glues. With a 1–2 second drying time and a runny consistency, it is user-friendly and suitable for Lash Technicians at several experience levels. We recommend Lady Bond for beginners looking for a slightly more forgiving adhesive.
Flexie quickly became a favourite when it launched in 2018. Its name comes from its ability to maintain a flexible bond, owing to its slightly more syrup-like consistency. Flexie also maintains its one-second drying time across a wider range of humidity levels than some of our other adhesives. It is best suited to more advanced Lash Technicians because of its fast drying time.
Like Lady Bond, Power Bond has been with us from the beginning and remains a firm favourite among Lash Technicians worldwide. Power Bond has a super-fast drying time of 0.5–1 second, so we recommend it for highly experienced Lash Technicians who can place extensions quickly and accurately.

Pretreatment Products
Good pretreatment can make the difference between a few days of lash retention and several weeks of retention. For the adhesive to bond properly, the natural lashes must be completely free from oils, makeup, skincare residue, dust and dirt.
We recommend our 5-Step Pretreatment Kit for a thorough cleanse. This routine also cleans the skin surrounding the eyes, reducing the risk of oils transferring onto the lashes and helping eyepatches and tape remain in place during the treatment.

Retention & Speed Booster
Although Retention & Speed Booster is primarily a pretreatment product, it is so well-loved that it deserves its own spotlight.
Booster has an alkaline pH that helps prepare the lash extension fibres for a faster bond and prevents handmade volume fans from closing during application. It should be applied to the base of the extensions while they are still on the lash strip and must not be used with Easy Fanning Lashes.
Because Booster accelerates the adhesive’s curing speed, newer Lash Technicians should consider whether their placement speed is fast enough before introducing it into their routine. If an adhesive cures before an extension is positioned correctly, it may prevent a strong bond from forming.
Superbonder
Superbonder is a finishing sealant applied to the adhesive bonds at the end of a lash treatment. It polymerises the adhesive without shock curing, adds flexibility to the bonds and locks in residual adhesive fumes.
Sets finished with Superbonder can safely get wet immediately, meaning clients do not need to wait 24 hours before washing their face, showering or swimming. Locking in the residual fumes can also help reduce post-treatment irritation. However, Superbonder does not make lash adhesive suitable for clients with an allergy, and it should never be treated as a way to prevent an allergic reaction.

Superbonder also helps keep adhesive bonds flexible. This makes it preferable to shock curing the adhesive with excessive moisture, which can make bonds brittle and leave behind white residue.
