Why your lash extensions don’t last (and what you can do about it)

For a lash technician, the most dreaded message is from a client complaining about their lash extensions not lasting.

Poor lash retention is a common issue that can leave both you and your clients frustrated.

The good news? Most retention problems can be solved with proper technique and the right tools.

In this post, we’ll explore the most common reasons lash extensions don’t last and provide actionable solutions to help you improve lash retention and keep your clients happy.

Common reasons lash extensions don’t last

1. Incomplete lash pretreatment

The foundation for long-lasting lash extensions, a correct pretreatment routine, is one of the most critical steps in ensuring great retention.

Eyelash extensions adhere best to a clean, oil-free surface. If the natural lashes aren’t properly prepped, the adhesive bond will be weak, leading to premature shedding of extensions (as a rule of thumb, the extensions should only fall off with the natural lash attached).

Tips for effective pretreatment

• Shampoo the lashes first and make sure to rinse thoroughly.
• Use a high-quality lash cleanser like our Charisma Eyelash Extensions Cleanser to remove oils, dirt, and makeup residue, but keep the natural lash happy and healthy. (Check out our pretreatment range designed for optimal results).
• Follow with a primer such as our Charisma Eyelash Extension Primer to ensure the lash surface is completely clean and ready for adhesive application.
• Avoid over-saturating the lashes with primer or cleanser, as too much moisture can interfere with the adhesive.
• Additionally, understanding your client's lash porosity can help you tailor your pretreatment and adhesive choice for optimal retention. Learn more in our blog post on hair porosity and eyelash retention.

2. Adhesive

Adhesive plays a significant role in lash retention.

Even if you’re using "the best" lash glue, improper technique can cause issues.

Because there’s no such thing as “the best adhesive,” it either works for you, or it doesn’t, depending on your speed, room conditions, and preference.

Key adhesive tips

• Use the right amount: Too much glue can create stickies, while too little means the glue half cures before touching the natural lash, and it won’t hold.
• Master your timing: Match your adhesive’s drying time to your speed. The speed of your glue does not define your experience - your clients’ lash retention does.
• Replace your glue every 4-6 weeks to ensure freshness. For more detailed information on selecting and using lash adhesives, refer to our comprehensive Lash Glue Guide.

3. Attachment

Proper attachment is essential for lash extensions that last.

Common mistakes, like attaching the fan to the top of the natural lash or failing to create a secure bond (known as wrapping), can lead to poor retention.

Attachment best practices

• Use a longer leg on your fans: This allows for more surface area to bond with the natural lash, creating a stronger hold.
• Attach at the base: Ensure the extension wraps around the natural lash for maximum adhesion.
• Avoid attaching from the top: While attaching from the top may work for some technicians, this practice is not ideal as you cannot see the contact zone, whereas attaching from the side or bottom gives you full control.

How to boost lash retention and keep clients happy

Educate them

Provide aftercare instructions and products - make sure to remind them every now and then how important it is to keep their lashes healthy.

Use quality products

Using cheap products doesn’t grow your profit.

Not only does this practice affect your work, but it may also cause irritations and allergies to your clients.

Investing in high-quality adhesives, pretreatment solutions, tools, and training sets you up for success.

Evaluate your technique

Regularly assess and refine your technique through practice or additional training.

Improving lash retention takes commitment

Improving lash retention takes attention to detail and a commitment to perfecting your craft.

By focusing on proper pretreatment, adhesive usage, and attachment techniques, you’ll see a noticeable difference in how long your lash extensions last and your clients will thank you for it.
