Worry not about your short and sparse lashes or thin eyebrows because the Organyc Growth Serum got both of your beauty woes covered, making it our top pick for the best eyelash growth serum.

Fortunately, this product comes to rescue our lashes from the damages we inflict onto it. It stimulates the lashes to grow longer and thicker within two months.

This serum contains eco-friendly ingredients that do wonders for the lashes.

For instance, Myristoyl Pentapeptide and Carboxymethylcellulose sodium, botanically-derived amino acids, influence keratin genes which moderate the length and size of eyelashes & eyebrows, resulting to visibly thicker and fuller lashes and brows.

Also, Myristoyl provides the nutrients that the hairs need to stay strong and grow longer quickly.

Another unique ingredient of this serum is the innovative grapefruit cell extract. The stem cells in the fruit extract act in synergy with the amino acids to produce dramatically thicker, fuller and longer eyelashes.

Lastly, this terrific serum uses Vitamin B3 to improve hair growth. Its benefits include improvement of blood flow to hair follicles, elimination of dry and brittle lashes, prevention of lash falling, and it also aids in the metabolism of keratin, a protein that supports hair growth.

We naturally wanted to try this serum after all the rave about it. We used it for a month, and we’re happy with how our lashes turned out – they’re fuller, longer, darker, and shinier.

Whether you desire longer lashes or thicker Cara Delevigne-like brows, the Hairgenics Lavish Lash is one of your best options for achieving both, making it one of our favorites in our little list of the best eyelash growth serums.

This serum claims to improve your lashes and brows in as little as 60 days by using botanically-derived compounds that penetrate hair follicles to stimulate and fortify hair growth.

Among its active ingredients are Panax Ginseng Extract, Swertia Japonica Extract, and Biotin.

Panax ginseng and Swertia Japonica extracts are herbal derivatives that are clinically proven to prevent breakage from root to tip for a more robust lash line. Also, they strengthen the lashes to avoid premature shedding.

Biotin is another terrific ingredient for hair growth. Perhaps you’ve even taken a Biotin supplement before if you’re a true blue beauty junkie (we’re very guilty of this!).

The magical biotin supposedly gives you a Rapunzel-esque hair, but you may ask “does it work for the lashes too?”.

Yes, it does. Biotin is a crucial substance in fatty-acid synthesis, making it a key factor for healthy and thick lashes and brows.

Hands down to this product – it’s amazing! We tried it for five weeks, and we noticed a significant difference in that short span.

Our lashes definitely looked gorgeous and noticeably fuller.

Castor Oil has a massive cult following because it was assumed to turn your limp lashes and brows into gorgeous and fluttering hairs.

The Namskara Organic Castor Oil made it to our great list of lash serums because some celebrities claim that it’s their secret to voluminous, thick eyelashes and naturally beautiful eyebrows.

The first thing we appreciated with this product is it included two applicator brushes for a simple application to lashes, brow lines and particular areas – very thoughtful indeed.

This product is cold-pressed, meaning it was never subjected to any form of heat during processing to prevent denaturation of active ingredients which may lower their potency.

The sole ingredient in this serum is the luxurious castor oil.

Castor oil provides a broad range of benefits. For one, it boosts lash growth and prevents them from breaking. This ingredient also provides deep moisturization to hair follicles for shinier strands.

Moreover, it can trigger the growth of eyelashes at places where they are not present in abundance – helping your lashes to achieve a fuller look.

Its benefits aren’t just limited to hair growth; castor oil also serves a natural body moisturizer that can reduce skin irritations and inflammation as well as keep wrinkles and fine lines at bay.

Being skincare fanatics, we’ve tried a couple of castor oil-based products, but we must admit that this is one of the few that delivers great results.

This product goes a long way although it came in just a 1oz bottle. The first thing we liked about the oil is it has a very subtle smell -- It doesn't matter how much you put on your eyebrows or eyelash, you could hardly smell it.

Also, the oil is not runny, and it easily targets a particular spot you want to treat without smearing it all over your face.

We absolutely loved how tiny hairs have grown into the spaces where they aren’t present before, making out lashes look fuller.

Pure’s Castor Oil is also cold-pressed and 100% organic. They contain zero fillers and additives – making it the purest of all castor oils.

This product nourishes and gives astonishing benefits from the hair on your scalp to your eyebrows and eyelashes.

For hair growth, it serves as a moisturizer to naturally soften the hair, and it also treats split ends, dandruff, and dry scalp.

Additionally, it boosts lash and brow growth for Lily Collins-inspired look. Who doesn’t envy her brows and lashes?

This product also does magic to the skin. Pure’s Castor Oil has natural antibacterial and antifungal properties. It's high in Vitamin E, which is highly regarded for its beautifying effects.

From postponing wrinkles and fine lines to reducing dark circles and acne treatment, this deeply nourishing castor oil produces moisturizing results you’ll fall in love with.

All of the oil’s beautifying benefits of castor oil is attributed to the various acids and fats it contains.

Some of the notable ones are Ricinoleic Acid, Oleic Acid, and Linoleum Acid that provides nourishment to keep the skin and hair healthy.

Since it’s castor oil, we already expected it to improve our brows and lashes. So far, it’s awesome – we can tell the difference in the thickness of ours brows and lashes. Our eyelashes also seemed stronger than ever.

The RapidLash Eyelash & Eyebrow Serum features utilizes a bevy of lash enhancing, conditioning, moisturizing, and strengthening ingredients. These work hand in hand to help improve the overall appearance of eyelashes and eyebrows.

It’s made exclusively with Hexatein 1 Complex. The complex is a potent combination of various potent ingredients such as peptides, biotin, panthenol, amino acids, soybean oil, and pumpkin seed extract.

The peptides work to stimulate hair growth and prevent breakage while biotin and panthenol seal in moisture to improve the health of lashes.

On the other hand, soybean oil infuses the lashes with essential vitamins to impart sheen and luster whereas pumpkin seed extract, which contains high amounts of amino acids and zinc, strengthen the lashes and prevent shedding.

This stuff, like all the other ones on our list, is absolutely amazing. We didn’t expect anything fantastic with this serum since it’s not that well known.

We asked someone with sparse and barely-there lower lashes try this product out. She was very surprised when she noticed her lashes growing longer and fuller in just nine days.

She loved how much longer her lashes have gotten as well as some of the sparse spots have filled in.
