Ever wonder, “how long does it take for eyelashes to grow back?” Find out more ahead.

Eyelashes are an important feature of your facial beauty. And them falling out is always a matter of concern, especially for grown-ups, because we all know that as kids, we believe that your wish would come true if you blow it on your eyelash.

But is it a matter of concern, how long does it take to grow back? It can easily regrow within 6 weeks, so a little over a month, and that fallen eyelash will already have been replaced. 

Although, pulling out an eyelash can result in an entirely different situation. Regrowth of the eyelash may take longer. This is because removing an eyelash from your eyelid can delay the replacement process. 

If you remove an eyelash before it has reached the end of the telogen phase, you will be preventing that eyelash from going through its normal life cycle.

Reasons For Eyelash Loss

There are many reasons why your eyelashes could be falling out. Some could be simply because you have rubbed your eye too hard or could also be due to some medical condition such as chemotherapy. 

Here is a list of reasons why your eyelash hair may be falling:

  • Alopecia – people diagnosed with alopecia lose their hair in patches because this condition leads to your immune system targeting your hair follicles. And your eyelash hair could also be under attack leading to eyelash fall.
  • Chemotherapy is a known fact that chemotherapy can result in hair loss, and as far as we know, eyelash hair isn’t exempted from the after-effects of chemotherapy.
  • Telogen effluvium – Stress causes your hair follicles to enter the telogen (resting) phase sooner than usual, causing your hair to thin or fall out. Typically, it is temporary.
  • Thyroid – The body’s natural activities, including hair growth, can be hampered by thyroid hormone levels that are either too high or too low.
  • Physical injury – incidents of physical harm such as burns or aggressively applying mascara can lead to your eyelash falling out. 
  • Medications – eyelash loss can be a side effect of some drugs, including anticonvulsants, anticoagulants, and botulinum toxin injections.

Eyelash Growth Cycle: how long does it take for eyelashes to grow back?

So the main question of the day: how long does it take for eyelashes to grow back?

Well, eyelash growth can take up to 16 weeks in an extreme scenario.

But, for understanding the growth procedure, it is also important to understand the three different stages of growth for eyelashes which are stated and explained below:

  1. Anagen stage 

 In this stage of development, follicles on the eyelids produce new hairs. Anagen, which determines the length of your eyelashes, typically lasts 1-3 months. At any given time, 40% of your hair is in this phase.

  1. Catagen stage 

 This stage lasts for 2-3 weeks. This stage should finish on its own to enable the development of new lashes. Therefore, if the eyelashes are removed during the catagen stage, the follicle remains empty until the end of the period. The follicles start to shrivel, and growth halts during this deterioration period.

  1. Telogen stage 

 This resting stage lasts between 4 and 9 months after the follicle reaches maturity. Almost half of your eyelashes are in this stage at any given time as they hang out until they fall out.

What Could be Affecting Your Eyelashes Growth?

There are numerous factors, but here is a list of those factors which are most likely could be affecting eyelash growth:


If you’ve lost or noticed that your hair is getting thinner due to a specific medicine, you might not start growing it again until you stop using it. For instance, carbimazole and propylthiouracil, two drugs used to treat thyroid disorders, might result in hair loss. You’ll need to wait till you’re done with chemotherapy if it’s the source of your hair loss.

Damaged Hair Follicle 

The hair follicle has been harmed. It could be more difficult for you to grow new eyelashes if your eyelash follicles have been destroyed.


The process of hair development can be slowed down by physical injury or a number of medical problems. Hormone imbalances and nutritional shortages may also impact how quickly hair grows back. These two issues must be resolved first.

What Can You Do To Speed Up The Growth of Your Eyelashes?

It can be upsetting to lose your lashes, but there are remedies and ways in which you could speed up the growth of your eyelashes.

Keep your eyes clean 

 Wash your face and eyelids with mild soap daily because it is crucial for maintaining the cleanliness of the skin surrounding your eyes. Avoiding strong moisturizers in the area is also beneficial because they risk clogging the glands on the eyelid.

Fully remove mascara 

If stiff, mascara-coated hairs press up against the pillow throughout the night, it increases the risk of lash damage. Be sure to remove your mascara gently, without pulling or rubbing it off too hard.

Healthy Diet 

 Since eggs are a good source of protein and biotin, two nutrients that are considered to promote hair development, think about including them in your diet. You might also consider increasing your iron intake by consuming foods high in iron, such as spinach. Hair loss has been linked to an iron shortage.

Since fatty acids are rich in protein, they also benefit your hair.

Castor Oil 

Castor oil can condition lash hair to increase the hair fiber’s elasticity. But this is not scientifically proven, so it is highly likely to be ineffective.

Lash serums 

An FDA-approved drug called Latisse may actively encourage the growth of new eyelashes. It is thought to function by prolonging the period that hairs spend in anagen, which promotes hair growth and the development of longer, fuller, and darker lashes.

A prescription from a doctor is necessary to purchase the topical treatment Latisse. 

Like applying eyeliner, you place it on your eyelid (not your eye) right above the lash line.

In Short

Eyelashes grow and shed in a natural and predictable manner. Even while this could raise concerns, you should be aware that they usually grow back untreated. Several home remedies and lifestyle adjustments can help you accelerate the growth process.

But an unnatural pattern of eyelash hair fall demands a doctor’s consultation. So if you do find it worrisome, do visit your doctor. Also, you can get more information about lash serums such as Latisse from them.
