A lash extension that starts twisting, leaning or turning sideways can be frustrating for both the lash artist and the client.
Sometimes it happens shortly after the appointment. Other times, a set can look perfect when it is finished and individual extensions begin changing direction as the natural lashes grow out.
There is not one single cause. Twisting can be linked to the weight and length of the extension, attachment and placement, the direction of the natural lash or simply how far the extension has grown out.
Why do lash extensions twist?
An extension relies on the natural lash underneath it for support.
If the extension is poorly balanced on the natural lash, excessively long or heavy for that particular lash, or attached at an awkward angle, it may become unstable and begin to rotate.
The timing can give you useful clues.
If the extensions are twisting very soon after application
If an extension begins leaning or rotating shortly after the treatment, look first at the application.
Possible causes include:
- insufficient attachment between the extension and natural lash
- attaching predominantly to one side of the natural lash
- poor direction when the extension was placed
- an extension or fan that is too heavy for the natural lash supporting it
- choosing a length that creates too much leverage
- applying onto a particularly curved or naturally sideways-growing lash without compensating for its direction
Good attachment is not simply about how much adhesive has been used. The extension needs enough stable contact with the natural lash to remain properly positioned.
Can lash extensions be too heavy?
Yes, but weight should be considered alongside the individual natural lash rather than using one rule for every client.
A healthy, stronger natural lash may comfortably support an extension that would be inappropriate for a much finer lash.
The artist should consider:
- natural lash thickness
- natural lash length
- strength and condition
- extension diameter
- fan size
- extension length
- how far beyond the natural lash the extension extends
Longer extensions also create greater leverage. This means that even a relatively lightweight extension can become unstable if significantly more length is added than the natural lash can comfortably support.
This is one reason lash mapping should never be based solely on the finished look the client wants. The natural lashes still determine what can safely and successfully be created.
For more on this, read our guide to assessing natural lashes before applying extensions.
Natural lash direction matters
Not every natural lash grows perfectly forwards.
Some grow sideways, cross over neighbouring lashes or naturally point in a different direction from the rest of the lash line.
Simply following the natural lash direction can sometimes leave the finished set looking messy. However, forcing an extension into a dramatically different direction without enough attachment can also make it unstable.
Good directional work involves balancing both.
The extension needs secure attachment while also being positioned so that the finished lash line looks intentional and consistent.
Why do extensions start twisting after a couple of weeks?
This can be completely different from an extension that twists immediately.
Natural lashes continue to grow while extensions are being worn. You can read more about how this affects retention in our natural lash growth cycle guide.
As the natural lash grows, the extension moves further away from the eyelid and the attachment point shifts further along the natural lash. This changes the balance of the extension and can make it more likely to lean, droop or twist.
This is one of the reasons regular infills are important.
Infills are not just about replacing lashes that have shed. They also give the lash artist the opportunity to remove extensions that have grown out too far and replace them before they become unstable, start twisting or create unnecessary leverage on the natural lash.
Regular maintenance helps keep the set looking neater while also allowing the artist to reassess the condition and growth of the natural lashes underneath. Our lash infill guide explains when a set may be suitable for an infill and when a full set may be more appropriate.
Could twisting mean the natural lashes are damaged?
Not automatically.
One twisting extension does not mean a client has damaged lashes.
However, if lots of extensions are rotating, drooping or becoming difficult to support, it is sensible to assess the natural lashes underneath.
Fine, weakened or damaged natural lashes may not support the same lengths, diameters or fan weights that healthier lashes can.
Repeatedly applying unsuitable extensions can also place unnecessary stress on the natural lashes.
The solution may be to reduce length, diameter or fan weight rather than simply trying to make the attachment stronger.
What about stickies?
Stickies can also interfere with the way extensions sit and grow.
If neighbouring natural lashes or extensions have been accidentally bonded together, the lashes cannot move independently as they grow.
This can pull them in different directions and may create discomfort as well as affecting the appearance of the set.
Thorough isolation throughout the treatment and a final check for stickies before the client leaves are therefore important.
Can sleeping on lash extensions make them twist?
Repeated pressure can contribute to lashes sitting differently, particularly when extensions are already considerably grown out.
Clients who consistently sleep on one side may notice that side looking less tidy sooner.
However, if freshly applied extensions are repeatedly twisting almost immediately, it is worth investigating the application, extension choice and natural lash direction rather than automatically blaming the client's sleeping position.
How can lash artists reduce twisting?
Choose extensions according to the individual natural lash rather than applying the same length and weight throughout the lash line.
Pay particular attention to:
- stable attachment
- extension direction
- natural lash direction
- appropriate length
- appropriate diameter and fan weight
- isolation
- removing excessively grown-out extensions during infills
Regular infills also help prevent excessive outgrowth from becoming a recurring cause of twisting.
If one area repeatedly twists on the same client, look closely at the natural lash growth pattern there. Sometimes adjusting the mapping or placement in that particular section makes a significant difference.
The important thing to remember
Twisting lash extensions are not caused by one universal problem.
A freshly applied extension that immediately rotates may point towards placement, attachment or an unsuitable extension choice.
An extension that starts turning several weeks later may simply have become too grown out to remain properly balanced.
Understanding when the twisting started, which lashes are affected and what the natural lashes underneath look like will usually tell you far more than assuming the client has done something wrong.
For professional lash artists, troubleshooting the cause rather than simply replacing the extension can help create neater sets, improve wear and protect the natural lashes over the long term.
