Lash Patch Test: Why and How to Do for Lash Extensions?

Lash technicians and clients both deserve a safe and pleasant lash extension experience. To prevent allergic reactions during application, it’s important to perform a lash patch test. The simple procedure can impact the well-being of clients and the reputation of any lash business.

If you’re a lash artist who hasn’t been offering patch tests, it’s time to start. By doing a patch test for eyelash extensions, you protect yourself and your clients from possible issues and showcase the professionalism that sets you apart.

The following article mentions how to do a patch test for eyelash extensions and why it is important for a safe procedure.

What is a Lash Patch Test?

So, exactly what is a patch test for eyelash extensions? When applying lash extensions, achieving the best outcome is necessary. To guarantee a successful application, a lash patch test is required. The test allows lash technicians to check if clients have any allergies or irritations to the eyelash extension products used during the treatment.

Applying a small amount of product to a specific area and waiting 24–48 hours can identify potential reactions. The primary focus of the patch test is to assess the compatibility of the adhesive, which is often the cause of allergic reactions. Through various evaluation methods, lash artists can determine whether proceeding with the product application for their clients is safe.

Do You Need Patch Test for Eyelash Extensions?

Whether you’re a new client or have had professional eyelash extensions before, a patch test is important. It ensures the safety of the lash glue used during your appointment. Even if you’ve had extensions previously, glues can change over time, making a patch test necessary.

Allergic reactions to eyelash extension glue can occur due to the adhesive itself or contact with other products like moisturizers or makeup removers. Conducting patch test for lash extensions helps determine if you have any allergies or reactions to the products used. It’s essential to perform this test as chemical allergies can manifest within 2–3 hours and may have severe consequences.

By conducting a lash glue patch test, the artists prevent clients from experiencing irritation or allergies to the adhesive glue, which can cause pain, itching, swelling, redness, and other unpleasant symptoms.

Although the exact reasons for its importance are unclear, the patch test contributes to the success or failure of eyelashes extension application. If you have sensitive eyes or skin, it is recommended to schedule a patch test, especially for first-time clients. It is always better to find an allergy with a small patch test rather than with a full set of lash extensions.

Why Should You Perform a Patch Test for Lash Glue?

Patch testing is essential to determine if your client is sensitive to lash extension glue. Regardless of their previous experience with lash extensions, reactions can still occur over time.

Conducting a lash patch test is a simple and effective way to ensure your client’s safety by identifying any adverse reactions. It is recommended to discuss the risks associated with eyelash extensions during the booking process and offer a patch test at that time.

If a client decides not to proceed with the patch test lash glue, it is important to document their decision and have them sign a waiver before proceeding with the treatment. Additionally, patch test must be done for clients who become pregnant, as they may experience heightened sensitivity to products that may not have caused any issues in the past.

How to Do Patch Test for Eyelash Extensions?

Performing a patch test for lash extensions is an important step to ensure the safety and comfort of your client. Here’s how to conduct a lash patch test safely and effectively:

1. Schedule Ahead: Always schedule the patch test at least 24 hours before the appointment to allow the adhesive to cure. The time can also be used for a full consultation, discussing desired styles, creating a lash map, and educating the client about aftercare.
2. The Extension Application Method: Apply around 10 to 12 extensions on the outer corners of the client’s eyes. It provides a reliable exposure similar to a full set of lash extensions but at a reduced volume. It allows for easy handling if any reaction occurs.
3. Avoid Glue on Lashes: It is not recommended to apply adhesive directly to the client’s lashes without attaching extensions. This method increases the risk of adhesive contact with the skin, which can cause dryness or irritation.
4. No Adhesives on Skin: Applying a dot of lash adhesive to the client’s skin, usually behind the ear, is an unreliable method. The reaction on other areas of the skin may not accurately reflect the reaction near the eyes, which are more sensitive.
5. Test Multiple Glue Products: If your client has reactive skin or eyes, you can test a few adhesives, such as dye-free or low-cyanoacrylate options. Apply one adhesive on one eye and another on the other eye, making sure to keep track of which is which.
6. Dealing with a Reaction: If your client experiences a reaction to the adhesive, have them return to the salon for removal as soon as possible. Mild reactions can be managed with cold compresses or eye drops, but severe or persistent reactions may require medical attention. If it was a simple irritation, you must do another patch test with a different adhesive at a later date. However, if your client had an allergic reaction, it is unlikely to resolve, and they may have a lifelong sensitivity to the adhesive.

Remember, following these steps will help ensure the safety and satisfaction of your clients regarding eyelash extensions.

What Does a Lash Extension Patch Test Reaction Look Like and What to Do?

Eyelash extension patch test reactions can result in two types: allergy (allergic contact dermatitis) and irritation (irritant contact dermatitis). Both reactions can cause redness, teary eyes, and red, swollen, or flaky skin around the eyes. Clients may experience discomfort such as stinging, itchiness, or pain.

Allergy reactions can occur immediately or hours after the application, with swelling of the eyelid and skin under the eye being an influential sign. Irritation reactions are usually immediate and caused by adhesive fumes or adhesive contact with the skin.

Removing the lashes and glue typically resolves the irritation. It is important to observe where the reaction occurs, particularly if it is concentrated under the eyes.

Sometimes, clients react to the glue from undereye patches or medical tape rather than the lash extension adhesive. To alleviate symptoms, clients can use antihistamines to reduce swelling and apply cold compresses. Using less glue, cleansing lashes with saline solution, and emphasizing lash cleanliness are recommended.

Make Lash Patch Test a Priority for Best Results!

Patch testing is a necessary step in the lash extension process, protecting both clients and the reputation of lash artists. Though it may seem bothersome, the consequences of a client developing an allergic reaction during treatment can be far worse.

By conducting a thorough lash patch test and consultation, lash artists can minimize the risk of complications and provide clients with the best possible eyelashes extension experience.

As professionals, it is our responsibility to prioritize client well-being and strive for a successful lash business. Remember, investing a little extra effort at the beginning can help achieve long-term benefits.
