(COSMO) - From politics to diets to raising kids, it’s hard to find things we can all agree on. Here are a couple everyone is definitely on the same page about…

One: every woman wants longer, fuller eyelashes and eyebrows.

Two: GROWTH SERUMS SOMETIMES WORK. That’s right, that ambiguous statement is 100% true. A range of prices, guarantees, and promises all result in one thing: some hair growth serums working and others utterly failing.

Recently we've been looking for a bundle sets that not only work, but give you a great deal to help nourish and grow your eyelashes and brows.

Lucky for you, we ranked FIVE great lash and brow bundles that should be on your radar.

Let's get started...

Effectiveness: 95%
Safety: 90%

Liaison has it all, a good value, safe ingredients, and (brace yourself) it works! Their bundle offers their famous Lash, Brow & Hair Bombshell Bundle. All three help condition and reactive follicles for fuller lashes, brows, and hair.

We tried Liaison after we found their 50% off discount code SECRET50. We gave it a six-week trial and found our journalist Stephanie Marianne’s eyelashes and brows to have a fuller look while her hair had filled in previously thinner areas. The ingredients are natural and don’t cause irritation or burning, and the instructions are straight forward and simple. The bundle includes Liaison's Lash Bond, Brow Bond, and their Hair Bond Spray.

It’s really the best of everything packed into one bundle. Effectiveness, safety, and value all rolled into one.

Bask & Lather has shown some good results with our reviewers and customers alike. Their Healthy Hair and Lashes Bundle is a good combo to start your journey, however it's about twice as expensive as Liaison's bundle. Not a great value in our opinion.

Effectiveness: 51%
Safety: 98%

If you were worried about price with Bask & Lather Set this one is going to blow your mind. At a whopping $135 this is one of the most expensive hair growth serum sets we've seen. Sure, it brings results, but nothing more impressive than Liaison and some of the others on this list. If you have the money, try this one out, but if you're just starting with serums, maybe try something that's more affordable first. To note - this is focused mainly on the hair on your head, but serums and supplements can help lashes and brows as well.

Nulastin is a great bundle for brows, lashes and hair. The price is still up there, especially because our reviewers found this product to run out the quickest out of any of the other bundles. Maybe the product itself is thinner or you need to use more to see effectiveness, we're not sure. Either way, it works if you're willing to pay the price.

If you're not worried about the hair on your head, but would rather focus on your lashes, brows, and eyes, UK Lash's Trio Bundle is perfect for you. They come with gel eye patches that can help revitalize your eyes and give you a younger, fresher look. Great set!

We wanted to talk further with our investigative reporter Stephanie Marianne on how Liaison Lash, Brow & Hair Bombshell Bundle worked for her. Stephanie tells the story.

Personally, I never believed in the effectiveness of growth serums and sprays. There’s a lot of brands out there claiming they work, but most don’t. I’ve had too many friends tricked into buying serums just to find out it’s a waste of money. So I’ve avoided it at all costs.

But then my best friend, who I trust with my life, swore by Liaison’s Lash, Brow & Hair Bombshell Bundle. She said it worked within 6 weeks. I, of course, didn’t believe her. But then she showed me her before and afters and I was stunned. Week by week, I could see her eyelashes, brows, and hair getting healthier and longer. I begged her to let me borrow her kit. Instead, she told me to use their discount code SECRET50 for 50% off!

RECEIVE 50% OFF WITH CODE SECRET50

I received the package within two days and started using it the Lash Bond and Brow Bond. The application is very simple, a small amount across your eyelashes and brows before you sleep. Similarly, after I shower, I use the Hair Bond Spray, working it down to my roots and scalp. Of course, I woke up the next day expecting a miracle… but alas, it takes longer than that to see results. But it takes longer than one night!

While I waited for longer lashes and brows, I looked into the science of Liaison. I wanted to know how it worked, and what it was aiming to do with my lashes…

Step 1: When you apply Liaison, a fresh supply of oxygen and citric acid work away at lash waste, releasing it through your pores to be washed away and clearing the way for nutrients.

Step 2: Our specialized mixture, including purified water and hyaluronic acid, activates internal peptides and gains access to follicles to prepare for bold growth.

Step 3: Polypeptides travel deep into your roots, supplying follicles with essential proteins throughout your day and while you sleep. Or, in the case of the mascara, it conditions as you wear it throughout the day.

Step 4: Refreshed hair follicles continue to receive the optimal oxygen, blood flow, and dose of nutrients needed to keep hair healthy and strong.

After about 3 weeks is when I began to notice the color of my lashes getting darker. 4 weeks and I noticed significant growth. My eyebrows as well grew in thicker which helped make them darker and fuller. On my head, my hair felt fuller and more luscious than ever.

Since then, I’ve continued to use the Bombshell Bundle every week for significant changes!
