Resolving Typical Lash Extension Issues: From Allergies To Lash Fall-Out

In the eyelash extension industry, eyelash extension has become a popular choice for many people to achieve beautiful eyes. However, despite the maturity of the technology, there are still some common problems that bother customers and eyelash extension technicians, the most common of which are **allergic reactions** and **lash loss**. This article will delve into the causes of these problems and provide professional prevention and remediation measures to help you enjoy a safer and longer-lasting eyelash extension experience.

I. Why can eyelash extensions cause allergies?

1. Allergies Caused by Adhesive Components in Eyelash Extensions
One of the main reasons for allergies during eyelash extensions is the adhesive used in the process. Traditional eyelash adhesives often contain volatile organic compounds (VOCs), formaldehyde, and acrylates, among other chemicals, which may irritate sensitive skin or eyes and cause redness, itching, tearing, and other uncomfortable symptoms. Especially for those who are prone to allergies, using the wrong adhesive can exacerbate the allergy reaction.



2. Contact dermatitis caused by improper handling
If the eyelash extension technician does not strictly control the amount of adhesive used during the procedure, or if the adhesive accidentally contacts the skin, it may cause contact dermatitis. This condition can not only cause redness, swelling, and irritation around the eye area, but also affect the healthy growth of eyelashes.

3. Individual Physiological Differences
Each person's skin and eyes react differently to different substances. Some people may be particularly sensitive to certain brands of glue, even if the brand is widely considered safe, and may still experience an allergic reaction. Therefore, choosing products that are suitable for one's skin type is crucial.

II. Why do eyelash extensions fall off?

1. Poor-quality eyelash glue
Low-quality eyelash glue may not provide enough adhesion, causing false eyelashes to fall off prematurely. Additionally, if the glue's quality is unstable, it may be affected by environmental factors (such as humidity, temperature) further weakening its adhesion effect. Especially in humid or sweaty environments, false eyelashes are more likely to become loose and even fall off.

2. Poor Operational Skills
The technician's operational skills also affect the durability of the eyelash extensions. If the technician fails to accurately align the false eyelashes with the natural ones during the application process, or applies too much or too little glue, it may cause the false eyelashes to become loose or fall off. Additionally, if the technician accidentally touches the client's natural eyelashes during the procedure, it may damage the natural eyelashes and cause them to fall out prematurely.

3. Improper Daily Care
If customers do not properly care for their eyelash extensions after the procedure, they may also experience premature shedding. For example, frequent rubbing of the eyes, using inappropriate makeup removers, swimming or soaking in hot springs, and other activities can accelerate the shedding of eyelash extensions. Additionally, excessive friction to the eye area or using oily skincare products may also affect the adhesive strength of the glue, causing the eyelash extensions to become loose.

III. How to avoid allergies and shedding?

1. Choose High-Quality Adhesive
To reduce the risk of allergies, it is recommended to choose certified, non-irritating eyelash adhesive. UV curable adhesive is a good choice as it contains no solvents and does not emit pungent odors, reducing irritation to the eyes and skin. Additionally, UV adhesive cures faster, allowing for a reduced risk of exposure to the adhesive for an extended period of time, which can lower the likelihood of contamination.



2. Conduct an allergy test
Before officially attaching eyelash extensions, it is recommended to conduct an allergy test. A small amount of glue can be applied to the back of the ear or the inner wrist, and you should wait for 24 hours to observe if there is an allergic reaction. At the same time, anti-allergic gel can be used during the grafting process to reduce the risk of allergies. If redness, itching, etc. appear, it is advised to replace the glue with another brand or choose other beauty methods.



3. Ensure proper operation
Choosing an experienced eyelash extension technician is very important. Professional eyelash extension technicians will strictly follow the operation procedures to ensure that each false eyelash is perfectly attached to the natural eyelashes and avoid contact with the skin. In addition, the technician will select the appropriate length and thickness of false eyelashes based on the client's eye shape and eyelash condition to ensure a natural and secure attachment effect.

4. Correct Daily Care
After eyelash extensions, clients need to pay special attention to daily care. Avoid rubbing your eyes frequently, and try not to use oil-based makeup removers or skincare products, as they can affect the adhesive strength of the glue. It is recommended to use a special eyelash cleanser or gentle makeup remover to gently wipe the eye area. Additionally, try to avoid activities such as swimming and hot springs that may accelerate the loss of false eyelashes.

IV. How to Address Allergies and Fallout Issues?

1. Dealing with Allergic Reactions
If you experience allergic symptoms after eyelash extensions, stop using the brand's products immediately and consult a doctor as soon as possible. Your doctor may recommend using anti-allergy medication or eye drops to alleviate symptoms. You can also use cold compresses to reduce swelling and itching in the eye area. If the allergic reaction is severe, it is recommended to remove the false eyelashes as soon as possible to avoid further irritation to the skin and eyes.

2. Repair Falling Out Lashes
If individual lashes on your extensions are falling out, you can contact your lash artist for repairs. Your lash artist can assess the extent of the damage and reapply the lashes to ensure a seamless, natural look. If the damage is more severe, you may need to have a full set redone. To avoid frequent falling out, it's recommended to schedule regular maintenance appointments with your lash artist to ensure the adhesive is holding well.

3. Protect Natural Lashes
When dealing with shedding issues, it's important to take care of your natural lashes. Over-pulling or using the wrong tools can damage your natural lashes and affect their healthy growth. Use a special lash conditioner to help keep your natural lashes strong and healthy. Additionally, trim excessive false lashes regularly to avoid unnecessary pressure on your natural lashes.


Eyelash extensions are a popular beauty service, but they also come with potential risks such as allergies and falling out. By choosing high-quality glue, conducting allergy tests, ensuring proper technique, and following proper daily care, you can effectively avoid these problems. If you do experience an allergic reaction or lash fallout, it is important to take prompt remedial measures. This article hopes to help you better understand the precautions involved in eyelash extensions and enjoy a safer, longer-lasting beautiful look.
