A lot of people are curious about how long it takes for eyelashes to grow back. Eyelashes are essential for protecting our eyes from dirt, dust, and other particles in the air. They also help keep our eyes moist. When eyelashes fall out, they usually grow back.
In this post, we’ll discuss how long it takes for eyelashes to regenerate. We’ll also speak about some of the elements that may influence your eyelash development.
Let’s go!

The Anatomy of an Eyelash
Before we get into how long it takes for eyelashes to grow back, let’s briefly touch on the anatomy of an eyelash. Each eyelash is attached to a hair follicle.
The base of the lash is called the bulb, and the shaft is the part of the lash that extends from the bulb.
The lifespan of an eyelash is about 90 to 120 days. At the end of this cycle, the lash will fall out and be replaced by a new one.
What Causes Eyelashes to Fall Out?
There are a few reasons why eyelashes may fall out. One of the most common reasons is when the hair follicle becomes damaged. This can be due to a number of factors, such as:
- Rubbing your eyes too hard
- Excessive use of mascara or other eye cosmetics
- Allergic reactions to cosmetics
- Damage from UV radiation
- Hormonal changes, such as those that occur during pregnancy or menopause
If you notice that you’re losing more lashes than usual, it’s important to see an eye doctor. They will be able to determine if there is an underlying cause that needs to be treated.

Is There a Risk of Damage to Lashes as a Result of Extensions?
If not done properly, lash extensions can damage your natural lashes. This is because the adhesive used to attach the extension to your lash can pull on the follicle and cause the lash to fall out prematurely.
In some cases, this can also lead to inflammation and infection.
How Long Does It Take for Eyelashes to Grow Back?
Generally speaking, it takes around eight weeks for an eyelash to grow back. This is the average time it takes for a new lash to reach its full length. However, keep in mind that this can vary from person to person.
There are a few factors that can influence the rate of eyelash growth, including:
- Age: As we age, our bodies naturally slow down. This includes the rate of hair growth. So, if you’re over the age of 40, it may take a bit longer for your lashes to grow back.
- Hormone levels: Our hormones play a big role in hair growth. For example, during pregnancy and menopause, women may experience changes in their hair. This can include thinning hair, as well as changes in the growth cycle of hair follicles.
- Eyelash damage: If you wear false eyelashes or use lash curlers, this can cause damage to your natural lashes. This can make them fall out prematurely and may even prevent them from growing back.
- Medication side effects: Certain medications can cause hair loss, including chemotherapy drugs and beta-blockers. If you’re taking any medication that’s known to cause hair loss, this may impact the rate of growth of your eyelashes.
