Patch Testing for Eyelash Extensions & Pre-Appointment Advice

Eyelash extensions provide clients with effortless beauty and confidence, but ensuring a safe and comfortable experience starts before the actual eyelash extensions application. One of the most discussed topics in the lash industry is patch testing - and while there are misconceptions about its necessity, at I AM Lash PRO, we strongly recommend it for both safety and professionalism.

The Truth About Patch Testing for Eyelash Extension Glue

There is a common misconception about patch testing for eyelash extensions adhesive. In the UK, cosmetic products that come into direct contact with the skin require testing. However, eyelash extension glue is not a cosmetic product applied to the skin - it is used to bond extensions to natural lashes. This means, from a technical standpoint, patch testing is not a legal requirement.

Despite this, at I AM Lash PRO, we believe in prioritising client safety and trust. A patch test is always a good practice, as it allows the client to identify any potential sensitivities before a full set is applied. While it cannot guarantee a reaction-free treatment, it is a precautionary measure that reassures clients and protects your lash business reputation.

Additionally, a client who is willing to come in for a patch test is usually more serious about their appointment and less likely to cancel last-minute. This small interaction also gives lash artists a chance to build trust, educate clients, and showcase their professionalism.

How to Perform a Patch Test for Eyelash Extensions

To assess fume sensitivity and potential reactions to the adhesive, apply 5–10 eyelash extensions per eye at least 48 hours before the full appointment. Clients should be instructed to monitor for any redness, itching, swelling, or discomfort.

Pre-Appointment Advice for Lash Clients

While performing the patch test, it’s a great opportunity to educate clients on how to prepare for their upcoming eyelash extensions appointment. Proper preparation ensures optimal lash extension retention and a comfortable experience.

1. Arrive with Clean, Makeup-Free Eyes

Eye makeup, especially mascara, eyeliner, and oil-based removers, can interfere with the Eyelash adhesive bond, leading to poor lash retention. Clients should thoroughly cleanse their lashes before their appointment.

Recommendation: To ensure the best prep, we recommend using the I AM Lash PRO Aftercare Kit, which includes a gentle lash cleanser, a soft cleansing brush, and a lash wand to keep lashes fresh and free from buildup.

2. If Lash Tinting Is Needed, Do It 48 Hours Before the Appointment

Clients with fair lashes may want to tint them before getting eyelash extensions. However, lash tint contains oils that can weaken the adhesive, so it must be done at least 48 hours before the lash treatment.

3. Remove Contact Lenses

To avoid discomfort, clients should remove contact lenses before the eyelash extensions appointment. They can wear glasses or bring a case to safely store their lenses.

4. Wear Comfortable Clothing

Eyelash extension appointments can take up to three hours, so it’s best to wear comfortable clothing. A blanket will be provided for warmth if needed.

5. Use the Restroom Before the Appointment

To ensure a smooth and relaxing experience, clients should visit the bathroom before their session begins.

Eyelash Extension Aftercare & Maintenance

Educating clients on aftercare is just as important as pre-appointment preparation. Proper maintenance helps eyelash extensions last longer and keeps natural lashes healthy.

• Avoid oil-based products around the eye area.
• Gently cleanse lashes daily using a lash-safe cleanser.
• Brush lashes regularly with a clean eyelash wand.
• Avoid excessive heat and steam within the first 24 hours.

Recommendation: The I AM Lash PRO Aftercare Kit is perfect for maintaining healthy lashes post-appointment. It includes everything needed for gentle cleansing and proper care to extend the life of lash extensions.

While patch testing for lash extensions adhesive is not a legal requirement, at I AM Lash PRO, we believe it is an essential step for client safety, trust, and professionalism. A patch test allows lash artists to demonstrate their expertise, strengthen client relationships, and reduce no-shows.

Additionally, by educating clients on pre-appointment preparation and proper aftercare, you set them up for the best possible retention and a luxurious lash experience.

For optimal lash health, we highly recommend the I AM Lash PRO Aftercare Kit - a must-have for every client to care for their lashes before and after appointments.
