Does Eyelash Serum Work On Eyebrows? 5 Things You Need to Know

Do you want thicker and fuller eyebrows but don’t want to invest in an eyebrows serum? Well, if you already have eyelash serum at home, then you probably wonder if it would work. After all, eyelashes and brows are body hair.
So, does eyelash serum work on eyebrows?
Eyelash serums can work on eyebrows because they contain very similar ingredients that add fullness and promote hair growth. The most common ingredients in lash growth serums and brow serums are botanicals, vitamins, peptides, and prostaglandin analogs.
Having said that, there are still some important differences between both products that you should know. These differences might make you buy each product for their intended use.
In this article, I am going to cover these differences. I’ll elaborate on the ingredients you should consider when picking the serums and how long they can take to grow your eyebrows.

What’s the Difference Between Lash Serum and Eyelash Serum?
There’s no denying that both eyelash and eyebrow serums can give you some awe-inspiring results. But are they really the same thing? Let’s break down the main differences between both products.
Ingredients
The main difference between eyelash and eyebrow serums is the specific ingredients. For example, eyelash serums often focus on lengthening lashes, while eyebrow serums may contain ingredients that help to thicken and fill in sparse brows.
Applicator
Finally, the applicator used for both products is slightly different. Lash serums typically come with a fine applicator to apply the liquid along the lash line. You want to aim for the root of the lashes very gently.
On the other hand, the brow applicator is generally thicker so that the product can be more easily applied to the root of the brow hair without losing too much product along the way.
Price
Also, eyelash serums tend to be more expensive than eyebrow serums. This is because they’re generally seen as more effective and have a higher concentration of active ingredients.
Does Eyelash Serum Work On Eyebrows?
If you’re like me, you’ve probably tried just about every beauty product on the market to help improve the appearance of your eyebrows. But eyelash serums can also give your eyebrows the needed volume.
If you’re unfamiliar with eyelash serum, it’s a special type of serum that’s specifically designed to help improve the appearance of your lashes. And after using it on your eyebrows for just a few weeks, you’ll notice a dramatic difference in the volume, thickness, and overall health of your brows.
Many people use eyelash serums on their eyebrows to help grow them out and make them thicker. If you have thin or sparse eyebrows, using an eyelash serum can help give you the fuller, more defined brows you desire.
Just be sure to apply the serum directly to your brows (not your lashes) and give it time to dry before continuing with your makeup.
Let me list a few benefits you can reap from eyelash serum.
- Eyelash serum speeds up the growth of eyebrows.
- It is perfect for you if you suffer from chronic hair loss conditions.
- The serum adds moisture and shine to your eyebrows, resulting in healthy, bushy, and beautiful eyebrows.
- It won’t cause any irritation or rashes.
- Eyelash serums provide a fuller and thick look to eyebrows.
How Long Does It Take To Grow Eyebrows With Lash Serum?

When it comes to the eyebrows’ regrowth, you need patience. Since the anagens in eyebrow areas are smaller than our hair scalp, the hair in this area takes time to grow back. Using a lash serum can speed them up between 3 to 6 weeks. However, the average time to grow eyebrows is between 3 to 4 months.
In addition to using eyebrow serums, there are a few hacks that you can follow to grow eyebrows.
- Try massaging the brow area with olive oil or castor oil. It can help stimulate growth.
- You can also try regularly exfoliating the area around your eyebrows to remove dead skin cells and promote new growth.
- Avoid plucking the hairs near your eyebrow to let them grow faster. Plucking hair near the eyebrow area can actually do more harm than good. For starters, it can lead to inflammation and even infection.
- Repeated plucking can damage the hair follicle, causing the hair to grow back thinner and weaker. In some cases, it can even cause permanent balding.
What Ingredients To Check While Choosing Eyelash Serum For Eyebrows?
Eyelash serums are gaining popularity these days as they offer a more natural way to enhance the appearance of your lashes as well as brows. There are many eyelash serums available in the market to grow eyebrows, but not all of them offer the best results. So, how do you choose the right one for you?
Here are 4 of the most important ingredients to look for while choosing an eyelash serum for brows. Make sure to choose a serum containing all these ingredients to get the best results.
Biotin
Biotin is a water-soluble vitamin that plays a vital role in your hair, skin, and nails health. It helps in the production of keratin, which is an essential structural protein that makes up your eyelashes. It also helps strengthen the follicles and prevent them from breaking. This, in turn, can help to promote lash growth.
Peptides
Peptides are short-chain amino acids that help to stimulate the growth of new cells and promote healing. They also work to increase collagen production, which can help to improve the volume and fullness of your eyebrows.
Green Tea Extracts
Green tea extracts are rich in antioxidants, which can help protect your eyebrows from damage caused by free radicals. Free radicals are unstable molecules that can cause cell damage and lead to the premature aging of your brows.
Antioxidants work to neutralize free radicals and prevent them from causing damage. Green tea extracts also have anti-inflammatory properties, which can help to soothe any irritation or inflammation around the eyebrow area.
Caffeine
Caffeine is a stimulant that can help increase blood circulation and promote the growth of new cells. It can also help to reduce inflammation and redness around the eyebrow area.
When used in an eyelash serum, these ingredients can help improve the appearance of your brows and lashes and promote growth. So, make sure to look for a serum that contains these key ingredients.
Why Would You Use a Lash Serum on Eyebrows?
I have to ask you this question…
Why do you want to use your lash growth serum on your brows in the first place?
We now know that both products are very similar when it comes to ingredients.1 Therefore, in theory you can certainly use an eyelash growth serum to grow thicker eyebrows.
But why would you?
I personnaly can only think of two reasons:
- You ran out of brow serum and therefore are using your lash serum temporarely.
- You don’t want to buy two products to save money.
For the first reason, I can totally understand since it happened to me once.
However, for the second one, I am not so sure. Althought it’s true that the initial investment in 2 products is more expensive, you also get more products! (I know captain obvious…).
If you only buy one lash growth serum to do your eyelashes and your brows, you will run out very rapidely and you’ll need to buy a new one sooner.
So in the end, I don’t think you’ll save much. Probably nothing at all.
Final Thoughts – Key takeaways
The bottom line is that while there are some slight differences between eyelash and eyebrow serums, they both can give you fuller, healthier-looking brows. Both products have very similar ingredients that will stimulate hair growth.
However, there’s no compleling reason to use a lash serum for your brows in the long-run. You could use your lash serum temporarely as an emergency, but it shouldn’t be considered a go-to solution.
What about you? Are you using a lash serum on your brows regularly?
