Takeaway

Eyelashes typically grow back in 6 weeks if there’s no damage to the follicle. You can try vitamin supplements or lash serums to help speed up growth.

You probably don’t pay too much attention when an eyelash falls out. What’s a missing eyelash or two when you lose several every day?

But if you start noticing lots of eyelashes falling out, that could signal an underlying problem.

Eyelashes do grow back except in rare cases — but some factors can slow down the process. Read on to learn more about the life cycle of an eyelash.

How long does it take for eyelashes to grow?

The life span of an eyelash can vary from 4 months to 11 months. There are three phases:

Growth phase: Also known as the anagen phase, this phase may last between 4 and 10 weeks. A typical eyelash grows between 0.12 and 0.14 millimeters per day.
Degradation phase: Also known as the catagen phase, this phase occurs when your eyelash stops growing. The hair follicle begins to shrink.
Telogen phase: Also known as the resting phase, this is the final phase during which the eyelash falls out.

How long does it take for eyelashes to grow after being pulled out?

It typically takes about 6 weeks for an eyelash to grow back if cut or burned as long as there’s no damage to the follicle or eyelid.

It can be a different story if you pull an eyelash out. If an eyelash is removed this way, it can take longer to grow back, and 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 typical life cycle of that eyelash.

How long does it take for eyelashes to grow back after extensions?

Eyelash extensions, which can be made of silk, mink, or synthetic fibers, can give you a glamorous look — until you have to remove them or they come off. In some instances, eyelash extensions, or the glue used to attach them to your eyelids, can injure your eyelash follicle and cause temporary or even permanent damage.

But if there’s no permanent damage, any lashes that fall out when you remove the extensions should grow back in around 6 weeks.

A caveat: If you’re a big fan of eyelash extensions, you may want to occasionally take a break to give your natural eyelashes a break.

How long does it take for hair to grow back after chemo?

Not all chemotherapy drugs will make you lose your hair, eyelashes, or eyebrows. But some do. And if you’re undergoing chemotherapy treatment with one that does affect hair growth, you can probably expect to start losing your hair within 2 to 4 weeks of beginning treatment.

Once you finish chemo, your hair will likely begin to regrow within several weeks.

What affects the regrowth of hair?

Many people are eager to regrow hair that has fallen out, but numerous factors can affect the process.

Medication: If you’ve lost hair or your hair has gotten thinner due to a particular medication, you might not regrow the hair until you stop taking the drug. For example, some medications used to treat thyroid disease, like carbimazole and propylthiouracil, cause hair loss. If your hair loss is caused by chemotherapy medication, you’ll need to wait until you’re done with it.
Damage to the hair follicle: If your eyelash follicles have been damaged, it may be harder for you to regrow those lashes.
Recovery: Physical trauma or various medical conditions can slow hair regrowth.

Other factors that may affect the hair regrowth process include nutritional deficiencies and hormone imbalances. Both of these will need to be addressed first.

Causes of eyelash hair loss

Madarosis is a condition that causes your eyelashes, eyebrow hairs, or both to fall out. There are many possible causes for madarosis to occur, including:

Genetics: If your parents or grandparents have thinning eyebrows, you might, too.
Alopecia: People with alopecia areata lose hair in patches because their immune system attacks their hair follicles. This condition can also include eyelashes and eyebrows.
Blepharitis: Eyelid inflammation can make you rub your eyes frequently, causing lashes to be dislodged.
Cancer treatment: Certain kinds of chemotherapy cause temporary hair loss, including the loss of eyelashes and eyebrows.
Telogen effluvium: Stress triggers your hair follicles to enter the telogen, or resting, phase earlier than usual, which can make your hair thin or fall out. It’s usually temporary.
Trichotillomania: This mental health condition occurs when you feel an intense urge to pull your hair out.
Thyroid conditions: When your thyroid hormone levels are too high or low, they can interfere with various processes in the body, including hair growth.
Physical injury: Trauma like a burn can cause your eyelashes or eyebrow hairs to fall out.
Lupus: This autoimmune disease tends to cause inflammation in your skin and can sometimes make your hair, including your eyelashes and eyebrows, thinner and fall out.
Medications: Some medications, including certain anticonvulsants, anticoagulants, and botulinum toxin injections, can cause eyelash loss.

Can I regrow eyelashes faster?

You may be wondering if you can speed up the regrowth process. Some strategies that people have tried include:

Supplementing with vitamins

You could try a vitamin in the family of B vitamins known as biotin to promote hair growth. Also known as vitamin H, biotin helps convert nutrients into energy and helps your skin, hair, and nails grow. But there’s only limited evidence to suggest that it’s effective for regrowing hair.

Eating a healthy diet

Consider adding eggs to your diet since they’re high in both protein and biotin, which are thought to help with hair growth. You might also consider boosting your iron intake by eating iron-rich foods like spinach. Iron deficiency is linked to hair loss.

Other foods that might promote hair growth include:

fatty fish
sweet potatoes
nuts

Applying castor oil

Do a quick online search and you’ll stumble across many claims that castor oils will regrow your eyelashes. But more scientific research is needed to determine whether castor oil can actually promote eyelash growth.

Past studies conducted on rabbits found castor oil treatments promoted hair regrowth.

Using eyelash growth serum

The premise: You paint a thin strip of serum along your upper lash line, and a few weeks later, you’re rewarded with thicker, longer lashes.

There’s evidence that certain preparations, such as the Food and Drug Administration (FDA)-approved prescription drug Latisse, may be effective.

However, it can cause side effects like irritation and even darkening the color of your iris. Other over-the-counter serums are available, but their ingredients are different and may not yield the same results.

The takeaway

Be as gentle with eyelashes as possible so you don’t accidentally cause any damage or additional loss. And if you start to notice that you’re losing a lot of eyelashes, talk with a doctor. There could be an underlying medical reason that needs to be addressed.
