An Introduction to Every London Lash Glue

Visit any website specialising in eyelash extension supplies, and you'll encounter a variety of at least three different lash glues. This diversity exists because Lash Technicians have unique preferences for texture, work under varying room conditions, possess different skill levels, and consider multiple other factors that influence their choice of adhesive. While personal recommendations are valuable, there's no universal glue that suits everyone. Therefore, it's beneficial to understand the specific characteristics of each glue option to make the most informed decision tailored to your own requirements and needs.

London Lash Glue Collection for Lash Extensions

Satin Bond

With a 2 second drying time and a satin texture, Satin Bond is the ideal choice for beginner Lash Techs, or for anyone who needs a 1 second drying time and has very high humidity. Satin Bond has a medium viscosity, which makes it easy to pick up the correct amount on the lash extension of volume fan when you’re dipping into it. 

Like the majority of other lash glues in the London Lash store (and in the wider market), Satin Bond works best in temperatures between 18-22℃, and favours a humidity level between 50-65%. If your humidity is higher than this, bear in mind that any glue you use is likely to cure quicker than advertised so if it is something of a problem for you, it’s well worth looking into a dehumidifier.

Lady Bond

Lady Bond has been part of the London Lash collection since the very beginning and has been a favourite of Lash Techs worldwide the entire time. With a 1-2 second drying time, Lady Bond is ideal for Lash Techs of all levels, and as such is the glue that we include in our Classic and Volume kits.

Lady Bond has a runnier texture than Satin Bond, which makes it very easy to pick up the correct amount of lash glue. Like Satin Bond, Lady Bond prefers a humidity level between 50-65%, and a temperature between 18-22℃.

Crystal Bond

Crystal Bond is London Lash’s only clear lash glue. Its characteristics are almost exactly the same as Lady Bond, however due to it being clear, it can be a little tricky for beginners to use as it’s harder to see at a glance if you have the right amount of glue on the lash or fan base. 

Crystal Bond being clear makes it the perfect choice if you’re using Coloured Lashes or Black Brown extensions as it provides a seamless glue bond. It’s also great for use with regular black lashes too, if you prefer to only use one lash adhesive. We also recommend Crystal Bond for any of your clients who may have an allergy or sensitivity to the carbon black pigment in the rest of our eyelash adhesives.

Flexie lash glue has became a fast favourite for many Lash Artists since it was launched back in 2018, and has continued to be one of our best selling glues since. Flexie has a 1 second drying time but works consistently in a wider range of humidity levels than other glues so has been a staple for Lash Techs with more changeable conditions. 

Flexie’s rapid drying time makes it a good choice for advanced Lash Technicians who are well used to placing lashes without needing to correct them – we don’t typically recommend Flexie for Lash Techs who have less than 2 years of experience, but like mentioned in the beginning, every Tech is different, and you may well be a fast lasher right from day 1.

Flexie works best in temperatures between 18-22℃, but maintains a consistent drying time in humidity levels ranging between 40-70%.

Power Bond

Similar to Lady Bond, Power Bond eyelash glue has been featured in the London Lash collection since the beginning. It is a very fast drying glue, curing in 0.5-1 second after being dipped. Needless to say this is for very experienced Lash Techs, and really needs you to keep a constant eye on your temperature and humidity levels as well as your placement speeds. 

Power Bond works best in temperatures between 18-22℃ and humidity levels between 50-65%. If you don’t already, it’s well worth picking up a Digital Hygrometer in order to monitor and maintain your room conditions.

Royal Bond

This is one of the newer additions to our glue collection. Royal Bond maintains its 0.5-1 second drying time in humidity levels between 30-80% which is a huge range and quite unlike any of our other adhesives. To that end, if you have issues with big fluctuations in your humidity during the day, Royal Bond will be the absolute best choice for you because it can keep up with those changes and give you great results regardless.

Let’s suppose for a moment that you place lashes in just under a second after you’ve dipped it into the glue. If your humidity is at 30% you will be fine with Power Bond, though it will be a little on the slow side. However, if your humidity goes up to 70%, you’re going to struggle to form a bond with Power Bond as it will be drying too quickly. In this case, you’d do well to have another glue on hand such as Lady Bond or Flexie. That’s a great method and we’d never discourage it, however using Royal Bond means you’ll actually be saving a little bit of money and you will only have to keep track of one glue, rather than two or more. You can read more about Royal Bond as a 'Two in One' lash glue here.

All in all, the glue you choose is a completely personal choice to you – consider your room conditions, your placement speed and your level of experience before you go ahead and purchase a full-sized bottle. We have Samples available if you want to try out a couple before making a commitment, and once you’ve found your favourite.
