(COSMO) - There’s an unfortunate truth to life we must all accept: the older we get the less hair on our head. Even the most luscious heads of hair will experience thinning and hair loss over time. It’s because the older we get the more toxins and sebum build up on our follicles, making it harder for them to get the nutrients they need. As well, our blood flow becomes restricted and slower, which prevents much-needed oxygen from reaching the hair as well. 

While some of us may decide to accept our fate and watch our hair get thinner and weaker, others will search for solutions to help their hair grow and become stronger and thicker with age. Believe it or not, it’s possible! 

Of course, with dozens upon dozens of products that claim more hair faster!... it can be hard to know exactly which products work and which are exactly right for YOU! 

That’s where Sephora is a big help!

As Sephora is one of the most popular beauty stores in the world, we figured they would have a good idea of what works. We asked Sephora employees around the country to give us their top recommendations.

And, wow, they delivered!

These Sephora employees gave us a list of the best FIVE shampoo and conditioner combos for hair loss that they believe are the best possible products on the market today. Some we reviewed as top contenders while some may be more specific to certain needs. Take a look!

Katie Esposito from California talks about our number 1 pick: "It doesn’t matter what kind of hair problems you’re experiencing, from thinning hair to unhealthy strands to baldness, Liaison’s Hair Bond Shampoo + Conditoner Bundle is a WINNER. I found out about Liaison when I was given the 50% off discount code SECRET50 to try the product. After a few weeks, I was blown away by the results. A Hair Bond Shampoo and Conditioner, each made with specialized formulas to work together to help reactivate hair roots and strengthen existing hair. Within weeks, I noticed a thicker, fuller head of hair. 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."

Bailey Williams from Chicago: "Vegamour has a similar shampoo and conditioner combo. Vegamour has made an effective combo that will help you grow thinning hair within a few months. The biggest drawback is the price, almost twice as much as Liaison (after their discount). Between the two we’d suggest Liaison first."

Marcy Phillips from New York loves Hers. "Hers is a high contender for helping thicken and regrow hair. They offer solutions for both women and men (Hims) that have proven effective. The most important ingredient they use is Minox which helps shed loose hair to make room for regrowth. The shampoo and conditioner help reestablish a thicker head of hair. While we like Hers and find them effective, their pricing can be a bit misleading. While it seems affordable, these bottles are small, and you’ll need to resupply yourself often, which can get expensive."

Jazlyn Pickett from South Carolina: "BondiBoost offers an overwhelming amount of products to help thicken and regrow hair. Their thickening duo is a great way to help keep hair strong, but we didn't find it as effective in regrowing hair. I found better results with Liaison. The price as well can become daunting if you keep needing to re-up your order. Stick with something simpler in my opinion."

We were recommended JVN through a few sources and had high hopes. The Hair Reviver kit comes with a shampoo, conditioner, and an extra hair serum that promise to help revive and restore your hair. However, what we found is a lack of promise in regrowing thinning hair and strengthening. While we loved this product, it may be better for people with damaged hair from bad hygiene, color damage, or general weak strands. For something that promises to help with thinning hair and hair loss, we recommend something more like if not Liaison.

All of these kits are terrific for helping stop thinning hair and strengthen follicles for the best, thickest head of hair possible. That said, Sephora's top choice, Liaison Hair Bond Shampoo + Conditioner Bundle, was because, of all these products, it showed the most effectiveness. Of course, a combo is only going to help, but obviously hair growth products can be expensive. So, if you had to choose just ONE… Liaison is QUEEN. 

We wanted to talk further with our investigative reporter Stephanie Marianne who helped create the rankings list to tell us why 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 my best friend, who I trust with my life, came over and I noticed her hair looked incredible. Not only was her hair looking thicker, but it was shining and fuller than ever. I asked how she did it and she swore by Liaison’s Hair Bond Shampoo + Conditioner Bundle. 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 the bundle immediately. LOL. 

I received the package within two days and started using it that day. The Hair Bond Shampoo + Conditoner Bundle promises to 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 Shampoo + Conditoner Bundle works and how it differentiates itself from other hair growth systems.

The Shampoo and Condioner each use a combination of essential oils and nutrients 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 Shampoo and Conditioner aim 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

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.
