(COSMO) - It’s an age-old problem… quite literally! A thinning, balding head of hair can start at a young age, but for most people, your hair starts thinning once you're over the hill. Of course, for about as long as the world has had mirrors, we’ve been trying to figure out how to stop our hair from looking weak and brittle. 

Luckily, there are more than enough products to help us reinvigorate and rejuvenate our hair to its full potential. But how do you choose which products to try? How do you know which will work and which won’t? That’s where we come in!

We’ve tested dozens of products that help thinning hair to determine our TOP FIVE choices. 

We compared effectiveness but also safety and price to make sure you find a solution for thinning hair that’s right for you!

This is by far our favorite choice when it comes to a simple solution for thinning hair that can reinvigorate hair follicles by stimulating blood flow to the scalp, triggering more hair growth while thickening and strengthening your hair. Liaison’s Hair Bond uses a Growth Bond Complex™ specifically focused on regrowing and strengthening hair. It’s better than any other product on the market today, loaded with essential nutrients to help keep hair healthy, including Citric Acid, Propylene Glycol, Ginseng Extract, Angelica Extract, Vitamin B6, and Biotin… to name a few! Liaison’s Hair Bond is best for people with thinning hair, weak strands, brittle split ends, and unhealthy roots. Best of all, it was the only product on our list offering a special 50% off discount code SECRET50, which made it one of the most affordable products on the market. Just a few sprays everyday can help strengthen your hair in weeks!

Keranique’s hair treatment is specifically designed for women with the FDA approved minoxidil, an ingredient proven to help women with female pattern baldness. While it’s given some proven results, it focuses primarily on baldness, which may not be the underlying issue when it comes to thinning hair. Often it's more about providing healthy nutrients to the follicles, which Keranique’s ingredients can’t promise. However, if you’re looking specifically to fight female patterned baldness, this may be the product for you. Just be aware you must use it twice a day, which means you’ll be needed to refill your order quite often, which can become very expensive.

A two-in-one product, Better Not Younger supplies a hair and scalp serum with a head massager comb for a high price that may be worth it for you. With effective ingredients including Niacinamide, Caffeine, and Gotu Kola, it helps reinvigorate hair roots and condition hair for a stronger, thicker follicle. The hair massager can help stimulate blood circulation to the scalp for additional help. While an effective product, the price tag is quite high for similar results you can receive from a more affordable product like Liaison’s Hair Bond.

Olaplex’s Intensive Treatment claims to make your hair three times stronger and more vibrant with just one use. We’re not that hopeful, but it certainly can help. The patented formula using bis-aminopropyl diglycol dimaleate, known as a β-unsaturated Michael acceptor can help rebuild and strengthen hair follicles for a thicker, fuller head of hair. Many reviews claim that it’s especially helpful for damaged hair from bleaching and coloring. While we do believe this is a great product, it’s a rather small bottle for its price tag, which means you’ll need to spend a lot of money to keep your hair looking fantastic.

Bondi is a great addition to any of these products because Bondi focuses on prevention. With its patented ingredient 3% Procapil®, it is clinically proven to reduce hair fall by up to 46% and increase hair density by up to 121%. A leave-in serum that can help boost any of the above products while helping keep your hair as full as possible. We recommend a combination of Bondi with Liaison’s Hair Bond. The perfect equation for a thicker, fuller head of hair. 

While we feel we recommended some great products for thinning hair to help rebuild hair follicles, activate roots, and strengthen your hair, we believe Liaison's product was the top choice. We wanted to talk further with our investigative reporter Stephanie Marianne who helped create the rankings list and how Liaison’s Hair Bond worked for her. Stephanie tells the story.

Personally, I never believed in the effectiveness of hair thickening, anti-baldness anything. “Time cannot be reversed,” I used to tell my friends. Too many of them have been tricked into buying some wild spray 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 Hair Bond. She would use it everyday after cleaning her hair in the morning, and a few sprays at night before heading to bed. After a few weeks, her hair looked thicker and fuller than ever before. She even had patches at the top of her forehead that seemed to have filled in quite nicely. It was even more impressive when she showed me the before and after images throughout the weeks of using Liaison’s Hair Bond. 

I had always been self-conscious about my thinning hair, so I begged her to let me borrow her Hair Bond, but instead she gave me a secret 50% off code, SECRET50, and I ordered my own Hair Bond immediately. 

I received a package two days later and applied the Hair Bond for the first time that night. The application is super simple, after your hair is cleansed and dried, spray the Hair Bond throughout your hair and gently brush it through. You don’t need to massage it in too much, just enough to make sure it’s distributed evenly. That’s all you need! 

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 works and how it differentiates itself from other hair growth products. 

A combination of essential oils and nutrients 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 even balding occur.

The key to a fuller head of hair starts with reactivating your roots, and that’s exactly what Liaison’s Hair Bond aims to do. With a Growth Bond Complex that’s filled with amazing ingredients that stimulate scalp blood flow while strengthening hair follicles. Some of the essential ingredients include:

CITRIC ACID Helps reduce build up of oil, dirt, and free radicals that often stifle hair growth. 

PROPYLENE GLYCOL An essential ingredient to helping hair lock in moisture for a stronger, thicker feel.

ORIENTAL ARBORVITAE LEAF EXTRACT Stimulates hair growth with increased blood circulation. 

​​ANGELICA EXTRACT Essential to stimulating blood circulation on the scalp for root reactivation. 

BIOTIN Essential vitamin B that helps support the enzymes that bring nutrients and oxygen to the hair. 

These, plus a handful of other helpful ingredients make Liaison’s Hair Bond an extremely effective way to regrow and support a healthier head of hair. 

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.
