Why Do My Eyelash Extensions Itch?


Poor Application Technique


One reason eyelash extensions may itch is due to poor application technique.

If the extensions have a sharp, needle-like base, they can sit too close to the delicate skin of the eyelid, causing irritation and itchiness.

Ensuring proper application by a trained lash technician is essential to avoid this issue.




Allergies are another common cause of itchy eyelash extensions.

An allergic reaction to the adhesive or the lash extensions can trigger eyelid dermatitis.

If you suspect an allergy, consult your lash technician or a medical professional for further advice.


Exposure To Fumes From Glue


Exposure to fumes from the glue used in the application process may also cause itchiness.

Formaldehyde, a by-product of the lash adhesive curing process, can result in irritation and mildly red eyes, leading to itchiness in some cases. However, this irritation is typically temporary and subsides within 24 hours.


Inadequate Aftercare


Inadequate aftercare is another factor that can contribute to itchy eyelash extensions.

If the extensions are not cleaned regularly and properly, debris and dirt can accumulate, causing irritation and itchiness.

Maintaining proper eyelash extension hygiene is crucial to prevent this issue.

How To Relieve Itchy Eyes From Lash Extensions


Clean Your Eyelash Extensions Regularly


Keeping your eyelash extensions clean is essential in preventing and relieving itchiness.

To do this, use a gentle cleanser specifically designed for eyelash extensions, and avoid using harsh or oil-based products that can weaken the adhesive.

Take Oral Antihistamines


Oral antihistamines can help alleviate itching caused by an allergic reaction to eyelash extensions or the adhesive used.

Use a Cold Compress

Remove the Lash Extensions


If the itchiness becomes severe or persists despite the above steps, it may be necessary to remove the lash extensions.

It’s essential to have a professional remove them to prevent damage to your natural lashes.

In some cases, taking a break from extensions and allowing your eyes to recover can be the best solution for itchy eyes caused by lash extensions.
