Many people experience headaches after getting lash extensions.

The Lash Extension Process

Before diving into the topic of headaches, let’s first understand the lash extension process

Lash extensions involve attaching individual synthetic lashes to your natural lashes using adhesive. This meticulous procedure requires a skilled technician and can take a couple of hours to complete. The extensions are designed to last several weeks, and proper care is essential to maintaining their longevity and appearance.

What Factors Cause Headaches After Lash Extensions?

1. Tension from Application: The application process involves your eyes being closed for an extended period, and technicians may use tape, patches, or other materials to keep your eyelids in place. This extended tension in the eye area can lead to muscle strain and potential headache triggers.

2. Positioning of Lash Extensions: If the lash extensions are placed too close to your lash line they might obstruct the natural flow of tears and eye fluids. This disruption can lead to eye strain, dry eyes, and eventually headaches.

3. Eyelash Weight: Lash extensions come in various lengths and thicknesses, and opting for lashes that are too heavy might strain your natural lashes and surrounding eye muscles. This added weight could contribute to discomfort and headaches.

4. Allergic Reactions: The fumes from the adhesive or the adhesive itself could cause an allergic reaction. Components present in eyelash adhesive like cyanoacrylate and formaldehyde have the potential to induce headaches in individuals who exhibit allergies to them. Although comprehensive scientific research is lacking in this domain, personal accounts suggest a link between eyelash glue usage and headache occurrences.

Many lash extension customers have experienced instances of eye irritation, migraines, headaches subsequent to applying eyelash adhesive.

Many lash extension customers have recounted instances of eye and nasal irritation, migraines, headaches, vertigo, and breathing difficulties subsequent to applying eyelash adhesive.

Moreover, customers aren’t the only ones experiencing health risks. According to a study performed by Occupational Medicine, a peer-reviewed medical journal published by Oxford University Press, many beauty professionals suffer from occupational rhinitis (OR) and occupational asthma (OA) after a period of regularly applying lash extensions to customers using instant glue containing cyanoacrylate.

Why Do Cyanoacrylate And Formaldehyde Cause Headache After Lash Extensions?

Eyelash glue contains two important chemicals: cyanoacrylate and formaldehyde. Cyanoacrylate is used in all types of eyelash glue, even the ones meant for sensitive eyes.

Headaches happen because our bodies respond to formaldehyde.

This is because cyanoacrylate is really good at making things stick together and drying quickly. Without it, your false lashes wouldn’t stay on your natural lashes. When cyanoacrylate hardens, it releases formaldehyde. Formaldehyde isn’t exactly added to the glue as an ingredient, but it forms when the glue dries. It is known to cause allergic reactions that can lead to headaches.

Formaldehyde affects individuals differently. Headaches happen because our bodies respond to formaldehyde. We’re not sure why some people are more affected than others. The allergic reaction occurs when the immune system responds to formaldehyde. When someone becomes allergic, their body makes special fighters (antibodies) to attack the formaldehyde. After being exposed multiple times, the reaction can get worse.

The majority of formaldehyde exposures happen through inhalation or by coming into contact with the skin or eyes. The substance is absorbed by the lungs, the gastrointestinal tract, and, to a lesser extent, the skin.

How To Avoid Headache After Lash Extensions

Now that we understand what factors cause headache after lash extensions, let’s move on to how to prevent this troublesome ailment.

  • Choose a Reputable Technician: To minimize the risk of headache after lash extensions and other discomfort, always opt for a reputable and experienced lash technician. An experienced lash tech is able to tell which type of lashes have the right length or weight for your lash line so that your eye area is not subjected to unnecessary tension. For people who are susceptible to allergies, a skilled lash specialist is also more capable of giving you advice on what’s safest for you, whether on the different types of adhesive or the different materials you may have allergic reactions to.
  • Patch Test for Allergies: If you’re new to lash extensions, consider requesting a patch test before the full application. This involves applying a small amount of adhesive behind your ear or on your arm to check for allergic reactions. If you notice any adverse reactions within 24 hours, it’s best to avoid lash extensions altogether.
  • Pick a Low-Fume and Odor Adhesive: Opting for an eyelash extension adhesive with minimal fumes and scent can significantly reduce the probability of experiencing a headache. Strongly odorous glues might trigger a negative response, raising the chances of headaches occurring. Utilizing adhesive with low fume levels can enhance your overall satisfaction and diminish the likelihood of encountering a headache afterwards.

  • Communicate Your Concerns: If you feel excessive tension or irritation during the lash extension procedure, it may later result in headaches. Therefore, communicate any discomfort or concerns you might have to your technician so adjustments can be made.
  • Choose Appropriate Lash Extensions: Consult with your technician about the appropriate length and weight of lash extensions for your natural lashes. Opting for lighter lashes can minimize strain and discomfort in your eyes.
  • Consider Eye Drops: Dry eyes can cause differences in the severity of headaches. If you experience dry eyes after getting lash extensions, eye drops recommended by an eye doctor can help keep your eyes hydrated, reducing the chances of headaches.
