(COSMO) - When it comes to the best beauty products and the biggest selection, most people tend to head to Sephora. They have everything. So when it comes to finding the most sought-after, popular products that you must have in your makeup bag, who better to ask than the employees with first-hand experience with every product available. 

We wanted to know which products every woman should have in their artillery. These Sephora employees gave us the best products for better lashes, skin, lips and more!

The first product recommended by a Sephora employee was Liaison Hair Bond 3-Step System, Molly Morrell, a Los Angeles employee explained, "It doesn’t matter what kind of hair problems you’re experiencing, from thinning hair to unhealthy strands to baldness, Liaison’s Hair Bond 3-Step System is a WINNER. We found out about Liaison when one of our co-workers was given the 50% off discount code SECRET50 to try the product herself. After a few weeks, she was blown away by the results. A Hair Bond Shampoo, Conditioner, and Post-Wash Spray, each made with specialized formulas to work together to help reactivate hair roots and strengthen existing hair. Within weeks, I noticed my co-worker's hair was thicker and fuller. Natural ingredients including strong-fighting antioxidants, peptides, and moisturizes, give your hair one of the best ways to be revitalized at any stage in your life. You absolutely need this one!"

Katie Esposito talked about this second product, The Glow Fairy Body Glow Wand. “If you’re looking to get rid of stretch marks, wrinkles, or cellulite, I LOVE this product. Its main ingredient is retinol, which is so popular right now, but mainly because it like, totally works. Just rub the balm over wrinkles, stretch marks, or loose skin and the retinol-packed balm will help revive the skin, making it look more youthful. It literally will glow!” 

Store Manager Wendy Brennen loved Laneige’s Lip Sleeping Mask. “It doesn't matter how much lipstick you put on, if your lips are dried and crack, people will be able to tell. And don’t even think about kissing someone! Laneige’s Lip Sleeping Mask helps take care of that by helping repair and moisture your lips overnight. It’s like a super-powered lip balm that will not only protect your lips but help them stay healthy. It’s really a great choice.” 

“Whether you think so or not, almost everyone could use some hair repair.” Sales associate Gina Ginsberg told us. “Our hair is so sensitive and even if you take amazing care of it, something like Olaplex’s No. 3 Hair Perfector will still help. It’s the smoothest, best hair conditioner and repairer ever. You can use it every day or like, once a month, either way you’d be doing a HUGE service to your hair.”

“What’s the point of amazing look if your makeup smears, right?” That’s what sales associate Catherine Lily wants to know. “I recommend this to everyone who shops at the store. I’m like chasing people down trying to get them to buy this it’s so good. Urban Decay’s All Night Long-Lasting Makeup Setting Spray helps keep makeup on and looking perfect all night. It lasts up to 16 hours, which is incredible. I used this at a summer wedding and I was the only one at the reception without running eyeliner and smudgy foundation. Absolute best!”

All of the products Sephora employees gave us are terrific and highly recommended. That said, their top choice was definitely Liaison's Hair Bond 3-Step Hair. 

We wanted to talk further with our investigative reporter Stephanie Marianne who talked to the Sephora employees to tell us how Liaison worked for her. Stephanie tells the story.

I’ve always had problems with my hair. It’s been thin and brittle ever since I was young. I’ve kind of accepted it. Personally, I’ve never been a big believer in hair products that promise Longer! Thicker! More Luscious Hair! To me they all promise a lot but never deliver and then you end up spending a lot of money with little results.

But then I mentioned Liaison to my best friend, who I trust with my life, and she immediately ran to her bathroom to show me the products! That'a when I noticed that not only was her hair looking thicker, but it was shining and fuller than ever. She said it worked within 4 weeks. I, of course, didn’t believe her. But then she showed me her before and after and I was stunned. Week by week, I could see her hair getting healthier and longer. I begged her to let me borrow the kit. Instead, she gave me a secret 50% off code, SECRET50, and I ordered two bottles immediately. LOL. 

I received the package within two days and started using it that day. The Hair Bond 3-Step System comes with a Shampoo, Conditioner, and Hair Bond Spray that help revitalize roots and activate hair growth. 

I, of course, was expecting immediate results, but it actually takes a few weeks to see real results. In the meantime, I started to do my research to find out how Liaison’s Hair Bond 3-Step System works and how it differentiates itself from other hair growth systems.

The 3-Step System uses a combination of essential oils and nutrients in each product to help not only strengthen hair but reactivate roots that have stopped growing long ago…

It’s quite simple, just as our bodies can exert less energy when we get older (remember staying up all night in your twenties?), our hair follows a similar pattern. When old hairs fall out, typically a new root is triggered and energy is spent building a new hair follicle. However, the older we get, the less energy is distributed to these roots. That’s when thinning and balding occur.

The key to a fuller head of hair starts with reactivating your roots, and that’s exactly what Liaison’s Hair Bond 3-Step System aims to do. Each with its own Hair Growth Complex that’s filled with amazing ingredients to stimulate scalp blood flow while strengthening hair follicles. Here’s the active ingredients in each product:

HAIR BOND SHAMPOO: Olive Oil, Peppermint Oil, Sea Buckthorn, Linseed Oil, and Squalane

HAIR BOND CONDITIONER: Argania Spinosa Kernel Oil and Ginger Essence

HAIR BOND SPRAY: Citric Acid, Pro

So, finally, after 4 weeks, I decided to check if I could see results… and wow! The areas of my hair that were previously patchy began to fill out. Plus my hair felt fuller and stronger. I was simply amazed at how good my hair felt.
