Growing Eyelashes

How long does it take for eyelashes to grow back?

Every now and then our eyelashes fall out and we hardly notice. For those who do, it can be quite disturbing for them.

You might want to know if they will ever grow back, especially when you have quite a number of your eyelashes falling out at a time. You might also have cut some of your eyelashes and wondered the same.

How long will it take for your eyelashes to grow back and why do they fall out in the first place? Read on to find out about all these.

How long does it take for eyelashes to grow?

Eyelashes have a lifespan of at least 4 to 11 months. This means that anywhere between 4 months up to 11 months, the eyelashes will be replaced with new ones. There are 3 phases of this life span namely;

  • the growth phase 
  • the degradation phase 
  • the resting phase

Growth phase

Also known as the anagen phase, this phase occurs between 4 to 10 weeks. An eyelash can grow between 0.12 and 0.14 millimeters per day

Degradation phase

This phase happens when your eyelashes stop growing. Shrinking of the hair follicles begins to occur. Your lashes stop growing for about two to three weeks.

This stage is also known as the catagen phase. 


This is the last stage of the lifespan of an eyelash. In this stage, the eyelash falls out and a new one grows in its place. It can last about 4 to 9 months. This stage is also known as the telogen phase.

How long does it take for eyelashes to grow back?

6 weeks is the general time it takes for the eyelash to grow back in case it is cut, burned and if there is no damage to the follicle or eyelid. 

If you pull out your eyelash it can take longer for it to grow back. This is because pulling an eyelash out of your eyelid can slow down the replacement process. 

Unless you happen to have perfect timing and manage to pull an eyelash out near the end of the telogen phase, you’ll be interrupting the normal life cycle of that eyelash.

What causes eyelashes to fall out? 

Losing an eyelash from time to time is pretty normal. If you are however losing a lot of eyelashes, there could be underlying conditions that need to be addressed before they can be restored. 

Here are some of the causes of eyelashes falling out;

Thyroid condition

A thyroid gland is a gland that produces hormones known as thyroid hormones. If the gland produces too much or too little thyroid hormone, it can cause a variety of symptoms, including hair loss. Loss of eyelashes can occur with both hyperthyroidism (overactive thyroid) and hypothyroidism (underactive thyroid). The lashes usually start to grow back after the thyroid imbalance has been treated.


If the eyelashes get burned but the hair follicles are intact, the eyelashes will eventually grow back within 6 weeks according to the American Academy of Ophthalmology. However, if the hair follicles were also damaged, the eyelashes might not grow back.


This is a medication used to treat cancer. It can sometimes cause the eyelashes to fall out. Drugs used for chemotherapy can cause hair loss.

Usually, eyelashes start to grow back shortly after stopping the chemotherapy.

Pulling out the eyelashes

An impulse pulling out of hair called trichotillomania is a psychological condition that affects some people. This impulse can affect hair anywhere on the body, including the eyelashes. Lashes that have been pulled out may take a few months to grow back.
