How Long Does It Take for Eyelash Extensions to Fall Out?

Eyelash extensions have become a popular beauty trend in recent years, offering women the opportunity to enhance their natural lashes and achieve a fuller, more dramatic look. However, one common question that arises is how long it takes for eyelash extensions to fall out.

The lifespan of eyelash extensions can vary depending on several factors, including the type of adhesive used, the quality of the extensions, and individual lash growth cycles. On average, eyelash extensions can last anywhere from two to six weeks before they naturally shed.

Understanding the Eyelash Growth Cycle

In order to understand why eyelash extensions fall out, it’s important to have a basic understanding of the natural eyelash growth cycle. The growth cycle consists of three phases:

  • Anagen Phase: This is the active growth phase where new lashes are produced. It typically lasts between 30 and 45 days.
  • Catagen Phase: This is a transitional phase where the lash stops growing and the hair follicle shrinks. It lasts around two to three weeks.
  • Telogen Phase: This is the resting phase where the lash remains in the follicle but is no longer growing. It can last up to 100 days before the lash naturally falls out.

Since each individual lash is in a different phase of the growth cycle at any given time, it’s normal for some lashes to fall out naturally while others are still growing. This is why regular maintenance and touch-ups are necessary to keep eyelash extensions looking full and even.

Factors Affecting Eyelash Extension Lifespan

Several factors can affect how long eyelash extensions last:

  1. Adhesive Quality: The type and quality of adhesive used to apply the extensions play a significant role in their lifespan. High-quality adhesives typically provide a stronger bond, resulting in longer-lasting extensions.
  2. Aftercare Routine: Proper aftercare is essential for maintaining the longevity of eyelash extensions. This includes avoiding oil-based products, excessive rubbing or touching, and using a gentle cleanser to remove makeup.
  3. Natural Lash Shedding: As mentioned earlier, natural lash shedding is a normal part of the growth cycle. When a natural lash sheds, the attached extension will fall out with it.
  4. Lifestyle Habits: Certain lifestyle habits, such as excessive sweating, exposure to heat or steam, and frequent swimming, can weaken the adhesive bond and cause extensions to fall out more quickly.

When to Schedule a Fill-In Appointment

To maintain the desired fullness and length of your eyelash extensions, it’s recommended to schedule a fill-in appointment every two to three weeks. During this appointment, the lash technician will assess the condition of your extensions and fill in any gaps caused by natural lash shedding.

Waiting too long between fill-in appointments can result in a more extensive touch-up process or even the need for a full set of extensions to be applied again. Regular maintenance is key to keeping your eyelash extensions looking their best.


While the exact time it takes for eyelash extensions to fall out can vary, the average lifespan is between two to six weeks. Understanding the natural eyelash growth cycle and practicing proper aftercare can help extend the life of your extensions. Regular fill-in appointments are essential for maintaining the desired fullness and length, ensuring that your eyelash extensions always look their best.
