(COSMO) - It’s an age-old problem… quite literally! Thinning, balding heads of hair can start at a young age, but for most people, your hair starts to thin during the older side of life. 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 becoming thinner, more brittle, and ultimately falling out. 

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!

Hair Growth Serums are concentrated oils filled with nutrients and peptides to help condition and activate hair growth. Of course, every formula is different and some serums work a lot better than others.

We’ve tested dozens of hair growth products to determine our TOP FIVE choices. 

We compared effectiveness but also safety and price to make sure you find the hair growth serum that’s right for you!

Let’s get started!

This is by far our favorite choice when it comes to a simple hair growth serum that can reinvigorate hair follicles by stimulating blood flow to the scalp, triggering more hair growth while thickening and strengthening your hair. Queen's Chebe Root Reactivation Serum uses a Growth Complex specifically focused on re-growing and strengthening hair. It’s better than any other product on the market today, loaded with essential nutrients to help keep hair healthy, including a high concentration of African Chebe Powder, Vitamin E, and Castor Oil, Queen's Chebe Root Reactivation Serum is best for people with curly but thinning hair with weak strands, and unhealthy roots. Best of all, it was the only product on our list offering a special 30% off discount code SECRET30, which made it one of the most affordable products on the market. Just a few drops everyday can help regrow and strengthen your hair in weeks!

Vegamour’s Advanced Hair Serum is a great companion to many of Vegamour’s hair growth products and does a good job in helping regrow and strengthen hair. We do love this product, but it’s quite expensive for similar results as Queen and other brands. If you’re willing to open up that purse and dig in, it’s a great recommendation.

Nutrafol promises stronger hair within 90 days, which is a great guarantee if it works. They’re using a patent pending formula with the main ingredient Ashwagandha Exosomes to help boost cell-renewal and activate thicker hair. This is a strong serum that certainly can help thicken your hair - but we did not see as much new hair growth as we would like based on other serum’s results.

A very interesting offer from Prose, this brand creates custom hair oils based on your specific needs. You start with a consultation to find your specific needs, including hair health, shine, moisture, and renewal. While a great offer, it’s quite expensive and doesn’t necessarily guarantee hair growth.

This multi-peptide serum is set at a really great price with a few strong ingredients. The main goal is to increase hair density through the use of Redensyl, Procapil, and Baicapil. While we like the price and reviews, we haven’t seen the results we think you can get with other products. Queen, which is close to a similar price, and have thousands of great reviews, also gave results far beyond that of The Ordinary, along with other products.

While we feel we recommended some great hair serum products to help rebuild hair follicles, activate roots, and strengthen your hair, we believe Queen'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 Queen's Chebe Root Reactivation Serum worked for her. Stephanie tells the story.

Personally, I never believed in the effectiveness of hair re-growth, anti-baldness anything. “Time cannot be reversed,” I used to tell my friends. Too many of them have been tricked into buying some wild oil or shampoo 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 Queen Chebe Root Reactivation Serum. She would place it in her hair everyday for 10 minutes before showering. 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 the Serum.

I had always been self-conscious about my thinning hair, so I begged her to let me borrow her Chebe Root Reactivation Serum, but instead she gave me a secret 30% off code, SECRET30, and I ordered my own bottle immediately. 

I received a package two days later and applied the Chebe Root Reactivation Serum for the first time that night before a shower. The application is super simple, you just add a few small drops of serum throughout your hair and rub it in down to the scalp. Then, you just let it sit for 10 minutes or so before starting your normal shower routine. 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 Queen's Chebe Root Reactivation Serum works and how it differentiates itself from other serum 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 balding occur.

The key to a fuller head of hair starts with reactivating your roots, and that’s exactly what Queen's Chebe Root Reactivation Serum aims to do. With a Hair Growth Complex filled with powerful ingredients:

AFRICAN CHEBE ROOT

A very specific oil that’s loaded with vitamins and fatty acids that helps stimulate blood flow to the scalp while also conditioning and strengthening hair strands.

CASTOR OIL

A thick oil that is known for its moisturizing and nourishing properties. It can help to keep the hair hydrated and protected from damage. Castor oil also contains ricinoleic acid, which has been shown to stimulate hair growth.

VITAMIN E

A natural oil that is similar to the sebum produced by the scalp. It can help to keep the scalp moisturized and prevent dryness, which can lead to hair loss.

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.
