Why Are My Lash Fans Closing? How to Troubleshoot Closed Volume Fans

There’s nothing more frustrating than creating a beautiful, fluffy volume fan, dipping it into your lash adhesive… and watching it close up before you’ve even finished the placement.

If your lash fans keep closing, the good news is that it’s usually down to a few simple factors: your adhesive, how much glue you’re picking up, your placement technique, your tweezers or your salon environment.

In this guide, we’ll troubleshoot the most common causes of closed lash fans and explain exactly what you can change to keep your volume fans open, fluffy and symmetrical.

Why do lash fans close?

The most common reasons for lash fans closing are:

• Your adhesive is too slow
• You’re picking up too much adhesive
• Your adhesive is travelling too far up the fan
• You’re not placing the fan quickly enough
• You’re not holding the fan in place for long enough
• Your lash tweezers don't have enough grip
• Your humidity is incorrect
• The natural lash moves during placement
• Your adhesive drop has started behaving differently

The key is working out when your fan is closing, as this can tell you exactly what needs changing.

1. Your adhesive is too slow

Volume fans need a fast-drying lash adhesive.

If your adhesive is too slow for your technique, the fan can move or collapse before the adhesive has cured enough to hold it in place.

This is particularly important when you're working with handmade volume fans. You need to be able to pick up your fan, dip the base into adhesive and apply it to the natural lash quickly enough for the adhesive to do its job.

If you're using a slower adhesive, you may find that the fan doesn't dry quickly enough once placed on the natural lash.

What should you do?

Make sure your lash glue drying speed matches your technique.

If your fan is closing because the adhesive isn't curing quickly enough, you may need to switch to a faster-drying adhesive rather than changing your fan-making technique.

2. You're picking up too much adhesive

This is one of the most common causes of closed lash fans.

When you pick up too much glue, the adhesive can travel up the stem of the fan. As it spreads between the lashes, it can pull them together and cause the fan to close.

You're aiming for a small, controlled amount of adhesive at the base, rather than a large blob.

How much adhesive should you use?

Only dip the base of your lash fan approximately 1-1.5mm into the adhesive.

After picking up the adhesive, check the base of your fan. You shouldn't see a large blob sitting there.

If you've picked up too much, you can gently tap the base of the fan against the edge of your adhesive holder to remove the excess.

The goal is a neat, controlled adhesive bead that stays at the base of the fan.

3. Your adhesive is travelling too far up the fan

Not all lash adhesives behave in exactly the same way.

A thin-viscosity adhesive will naturally travel further up the fan than a thicker adhesive. If you're using a thin glue, you may need to adjust how much of the fan you dip into the adhesive.

Using a thin adhesive?

Don't dip as deeply. Keep your adhesive pick-up particularly controlled and stick to around 1-1.5mm at the base.

Using a thicker adhesive?

A thicker adhesive can allow you to pick up a slightly larger bead at the base, but you still don't want excess glue travelling up the fan.

Avoid dipping too slowly, as this can allow more adhesive to collect around the base.

A quick, controlled dip is much easier to manage.

4. You're not applying the fan quickly enough

Once your fan has touched the adhesive, you need to get it onto the natural lash as quickly as possible.

Your adhesive is already beginning to cure, so don't spend too long searching for the perfect natural lash after dipping.

Your movement should be:

Create your fan → dip the base → remove excess if needed → apply to the natural lash → hold.

The more time you spend between dipping and placement, the more likely the adhesive is to start curing before you've secured the fan.

5. You're letting go too soon

Getting the fan onto the natural lash is only half of the job.

You also need to hold it in place long enough for the adhesive to secure the bond.

If you let go too quickly, the fan can collapse or move before the adhesive has cured enough to hold its shape.

As a general guide, hold the fan in place for around 2 seconds, but always take your adhesive's drying speed into account.

A faster adhesive may need less time, while a slower adhesive may need longer.

The important thing is that the fan should feel secure before you release it.

6. Your tweezers don't have enough grip

Your volume lash tweezers need to give you enough grip and control to pick up the fan without crushing or distorting it.

If your tweezers don't have a good enough grip area, you may find yourself squeezing the fan too tightly or struggling to hold it securely.

This can cause the fan to close during pick-up or make it harder to control when you're moving towards the natural lash.

If your fans are closing before they even reach the glue, take a look at your tweezer technique and whether your tweezers are giving you enough grip.

7. Your salon humidity is incorrect

Your lash adhesive is affected by humidity, so your salon environment can have a direct impact on how your glue behaves.

If your humidity isn't within a suitable range, your adhesive may cure differently and this can contribute to fans closing during application.

For best results, aim for a humidity level of around 40-60%, unless your specific adhesive manufacturer recommends otherwise.

If your fans are behaving perfectly one day and suddenly closing the next, check your hygrometer before assuming your technique has changed.

8. Your adhesive drop has started behaving differently

If you've been working with the same glue dot and suddenly notice that your fans aren't behaving as they normally do, check your adhesive dot.

Your glue drop is exposed to the surrounding air and humidity while you're working, so its performance can change over time.

If your adhesive starts to feel stringy, thick, slow or simply different, don't try to work around it, just change it.

A fresh glue drop can make a noticeable difference to the consistency of your application.

9. The natural lash is moving

Sometimes you've done everything right and the natural lash is the problem.

Natural lashes can move slightly while you're placing a fan. If the lash moves before the adhesive has secured the fan, it can cause the fan to shift or close.

Make sure you have good control of the natural lash during placement and avoid releasing the fan before the adhesive has had enough time to hold it securely.

This is another reason why holding your fan in place is so important.

What to do if your fan has already started closing

If you notice a fan beginning to close, don't try to force it back open once it's already attached.

A closed fan can create an uneven or unsymmetrical base, which can affect the overall finish of your lash set.

It's usually better to remove the fan and replace it with a fresh one.

Trying to manipulate a fan that has already started curing can result in an untidy base and unnecessary stress on the natural lash.

How to prevent closed lash fans after the appointment

Your job doesn't necessarily finish when the client leaves.

Before completing the lash set, check your fans carefully with your tweezers to make sure none have closed or stuck together during application.

If you spot a fan that has closed slightly and can be safely separated, gently separate it with your tweezers. If the fan has already formed an uneven or compromised base, it's better to remove and replace it.

Don't forget lash aftercare

Make sure your client understands their lash extension aftercare before they leave.

Following the correct aftercare routine helps protect the lash extensions and maintain the finished look between appointments.

Remind your clients to follow your recommended cleansing and aftercare routine and avoid anything that could interfere with their lash extensions.

A quick checklist for closed lash fans

When your lash fans keep closing, don't immediately assume your fan-making technique is the problem.

Start by looking at your adhesive speed, adhesive amount, dipping technique, placement speed, hold time, tweezers and humidity.

Most importantly, pay attention to when the fan closes.

If it closes as soon as it hits the adhesive, look at your glue and adhesive amount. If it closes while you're placing it, look at your speed and technique. If it moves after placement, check your hold time and natural lash movement.

Small adjustments can make a huge difference to the consistency of your volume lash extensions and help you create the fluffy, symmetrical lash fans you're aiming for.
