Lash Glue Retention Booster 10ml – Cherry or Unscented

Designed to support lash adhesive curing in lower-humidity environments and help with controlled handmade Volume fan pickup.

Our UK-made, cosmetic-grade Retention Booster is designed for professional lash artists working in drier conditions where cyanoacrylate adhesive may be curing more slowly than expected.

It can also be applied sparingly to the lash strip during handmade Volume work to help with fan control.

Available in Cherry Scent or Unscented.

Size: 10ml
Best for: Lower-humidity lash rooms and handmade Volume techniques
Use: Natural lash preparation or lash-strip application, depending on technique
Not recommended for: Easy Fan lashes
Professional use only

What Does Retention Booster Do?

Cyanoacrylate lash adhesive reacts with moisture.

When humidity is lower, your adhesive may cure more slowly. This can affect your workflow and may leave lashes mobile for longer after placement.

Our Retention Booster is designed to help create a more suitable lash surface in drier conditions, supporting a faster and more predictable curing response.

It does not replace correct room conditions or the need to choose an adhesive that matches your application speed.

When Should You Use It?

Retention Booster can be particularly useful when:

• Your room humidity is lower than usual
• Your adhesive is curing more slowly than expected
• Lashes remain mobile after placement
• You are experiencing more stickies because the adhesive is curing too slowly

If your adhesive is already curing quickly, adding Retention Booster may make it too fast and can contribute to poor attachment or pop-offs.

Use it when needed - not automatically on every client.

How to Use on Natural Lashes

Apply a small amount using a clean microbrush or suitable applicator.

Avoid over-saturating the lashes.

Allow the product to dry before beginning lash application.

Always assess your working environment and adhesive behaviour first.

How to Use for Handmade Volume Fans

A small amount can also be applied to the lash strip before creating handmade Volume fans.

This can help keep the fibres more controlled during fan-making and support cleaner fan formation.

Apply sparingly with a micro applicator.

Avoid overloading the strip.

Not Recommended for Easy Fan Lashes

We do not recommend using Retention Booster on Easy Fan lashes.

Easy Fan trays are manufactured differently from standard handmade Volume fibres, so additional product on the strip may interfere with how the base is designed to work.

Can Retention Booster Improve Retention?

It can support retention indirectly by helping your adhesive cure at a more appropriate speed in lower-humidity conditions.

But retention also depends on:

• Adhesive speed
• Temperature and humidity
• Natural lash preparation
• Attachment
• Application technique
• Client aftercare
• Natural lash cycle

It should not be treated as a fix for every retention issue.

Cherry or Unscented?

Choose according to your preference.

Cherry Scent is the fragranced version.

Unscented is available for artists who prefer a version without the added scent.

First Time Using Retention Booster?

If you'd prefer to test it before committing to the full-size bottle, we also offer a 1g Lash Glue Retention Booster Sample.

That gives you the chance to see how it behaves with your adhesive and working environment first.

The Bottom Line

Low humidity can make cyanoacrylate adhesive cure more slowly.

Our Retention Booster gives lash artists another tool to help manage that, while also offering useful control during handmade Volume fan-making.

Use it sparingly and intentionally.

The goal is not to make every adhesive faster.

It is to help your adhesive cure at the right speed for your technique and environment.
