How Fast Do Lashes Grow

How fast do lashes grow? The good news - lashes grow back in a few weeks!

In this article, we'll cover:

  • How long does it take for eyelashes to grow
  • 4 stages of growth - the short answer
  • Common reasons for lash loss
  • The best way to prevent lash loss in the first place

According to the American Academy of Ophthalmology, we have a between 90 to 150 eyelash hair follicles the upper eyelid and 70-80 on the lower eyelid.

And just like the hair growth cycle on other parts of the body, each eyelash growth cycle is in different stages, growing, maturing, and falling out - making room for new hairs.

Growth of eyelashes - entire eyelash growth cycle

How long does it take for eyelashes to grow back? For most people it can be as short as 4 weeks. Surprisingly the entire eyelash growth cycle is not that long.

The amount of time for a normal cycle for natural eyelashes is broken down into 4 stages:

  • Anagen Phase

Natural lashes have about a 4 to 8-week growth phase. The natural growth cycle of lashes starts with keratin-producing skin cells that come through the hair follicle on the upper and lower lashes. These cells harden and slowly become new eyelashes.

  • Catagen Phase

The catagen stage is the next phase is where the eyelash hair health reaches its full growth potential. If there is any damage of the follicle the lash falls out during this time and it won't grow back until this phase is completed. The catagen phase takes about 2 weeks.

This is the most important phase in terms of your beauty routine for fuller lashes. This is when nutrients to support eyelash growth can be very helpful.

This is an important time use your best eyelash growth serum, or castor oil, olive oil, coconut oil, jojoba oil, vitamin e, or any product with an active ingredient to support and strengthen hair growth.

You want to bathe your eyelashes with key nutrients to keep them healthy, prevent premature hair loss and help lashes reach their highest potential growth for longer eyelashes.

  • Telogen Phase

This is the resting phase. The lashes are no longer growing, the follicle is inactive and the hair will fall out after this transition phase is over. The more gentle you are in this stage (like using a gentle makeup remover), the longer you get to show off those pretty long eyelashes.

  • Exogen Phase

This is the start of the eyelash regrowth process as they begin to fallout - making room for new lashes to form.

This lash loss and regrowth process is a perfectly natural process for the average adult. However, if you have any medical conditions like autoimmune disease, thyroid conditions or are taking chemotherapy drugs for cancer treatment, the hair replacement process might be slower. In fact, side effects such as stunted growth or even permanent damage is possible for some underlying conditions.


What helps your lashes grow

False eyelashes

Because your lashes are all at different growing stages (otherwise they'd fall out all at once!) it's important to keep them healthy all the time, not just during the Catagen growth phase.

Some people do this by applying natural ingredients (whether it's plain old petroleum jelly or your favorite eyelash serum) to your lash line daily to support healthy hair growth. And remember, since eyelashes are 90% protein, eating a healthy diet can help too.

How to grow natural lashes - Good makeup habits for thicker lashes

For longer lashes it's important each hair has a chance to reach it's full potential before falling out. Try to practice good makeup habits for best results.

  • First thing, be gentle around the eye area when removing makeup. The use eyelash extensions, false eyelashes, eyelash curler, and waterproof mascara on a regular basis can cause permanent eyelash loss.

Both fake eyelashes and waterproof formulas are hard to remove and can result in broken stubby eyelashes.

Personally, for me, just leaving eye makeup on at bedtime will cause my lashes to break off. The worst thing for most women - is the constant use of false lashes.

OTC lash serums - grow lashes fast?

While lash serums don't actually increase how fast lashes grow, they can help improve lash strength so they can grow to their full potential. As a result, you'll have long lash around for a long time during the resting phase.

I always try to apply a natural serum for lashes to grow and to improve the flexibility of the hair fiber, and help keep them longer - especially for my upper eyelashes. It's a good idea to use serums that also contain lash conditioners.

Lash conditioners can also help keep your lashes around longer during the telogen phase (resting phase).

How Fast Do Lashes Grow - FAQ

Q: Rodan and Fields Lash Boost vs Latisse - Which one is better?

A: It's important to understand that Rodan and Fields Lash Boost is an over-the-counter lash boost serum cosmetic product.

On the other hand, Latisse is a prescription product with FDA approval. It contains the active ingredient bimatoprost.

Latisse was originally formulated to treat glaucoma and it contains isopropyl cloprostenate which is a prostaglandin analogue. While this ingredient helped glaucoma issues it has potential side effects and allergic reactions and should be used with the approval of your eye doctor.

Rodan and Fields Lash Boost had a reputation for being an effective eyelash enhancement product, however, as an over-the-counter lash boost product, the price point of Fields' Lash Boost is not very good. Even compared to prescription Latisse.

Since everyone is different, when it comes to eyelash growth products, you really have to try and compare similar products and view the possible side effects of each one. And, evaluate which ones fit best with your budget too.

Personally, I've tried the prescription Latisse and it did work, but I suffered from the common side effects such as red eyelids and itchy eyes. Plus, it was expensive.

I'm now trying out a over-the-counter lash conditioner and I'm very happy with my results. The key ingredient is a peptide complex and I think it's a pretty good product. It's help enhance the appearance of lashes in a matter of weeks.

Q: What is the best way to apply eyelash serum. Do I apply to both the upper and lower lashes?

A: No, you only need to apply the serum to the upper eyelids, as if you were applying a liquid eyeliner. Just close one eye and run the wand across the upper lash line and then repeat on the other eye.

No need to apply the lash serum to your lower eyelid lash, the serum will naturally apply to the lower lash as you blink.

Q: I was wondering if biotin supplements help grow thicker eyelashes? I know it's recommended for scalp hair growth. I've been wearing false eyelashes for months and now my lashes are all broken, spars and thin.

A: From what I understand biotin supplements help support healthy skin, nails and hair. But there isn't much research to prove that it will increase hair growth or support eyelash hair follicle growth.

However, if you're low on biotin, I'm sure it can't hurt to give it a try. Also, make sure you're getting enough protein, as amino acids help support hair growth too.

The best thing to encourage growth is to stop using false eyelashes and eyelash curlers until they resume a health growth. I know that's hard to do when your eyelashes are broken and spars, but remember, lashes grow back fast, in just a matter of weeks.

At the same time, consider trying eye lash growth serums that contain conditioners. I know they work!
