Arey refers to their products as the “Wrinkle creams of hair products”. Clever. Their high-end packaging and diverse product line make them a strong contender for the top spot. However, we found that their shampoo wasn't as effective as we had hoped, with Refress outperforming them. Although it's a bit pricey, it's not the most expensive option out there. It's worth noting that Arey offers a range of products aimed at treating aging and brittle hair, which is a plus.

Prose has gained significant attention for its personalized beauty products that are tailored to your specific requirements. Through their 10-minute questionnaire, they gather all the necessary information about your hair and lifestyle to create a unique shampoo that works for you. Although their shampoo provides ingredients that help with reversing gray hair, it is not their primary focus. Instead, their main goal is to provide personalized products that cater to individual needs.

Reminex may be a budget-friendly option, but it may not be the most effective when it comes to reversing gray hair. The reviews were mixed and showed inconsistent results. However, if you're looking for a slightly more affordable option, it might be worth considering. That being said, Refress's sale price is more attractive, and it has been shown to deliver better results. Therefore, we would suggest starting with Refress instead.

While it's always good to stick with a classic, Just For Men's hair coloring product is a little too heavy on chemicals and may not be the best option. While the product may work, some reviews have noted that it can be messy and may stain your hands, so it's important to use gloves.


While we believe we recommended some great shampoos to help reverse gray hairs in women, we believe Refress Hair Darkening Shampoo Bar is the absolute best option. We wanted to talk further with our investigative reporter Ellie Williams who helped create the rankings list and how she discovered the greatness that is Refress.

I've always had issues with gray hairs. It runs in my family, and I started noticing them when I was in my early 30s. And personally, I never believed in shampoos that claim to reverse gray hair. There are so many brands out there that promise to work, but most don't. I've had too many friends who were disappointed after buying shampoos that didn't deliver results. So, I avoided them at all costs. 

So when I was put on assignment to find some amazing hair growth products, I was happy to test some things out. Unfortunately, not a lot made the cut. Too many products felt, smelled, and contained strong chemicals that felt more like medicine than shampoo. And worse, they didn’t really work that well.  

I sort’ve gave up.

But then, I heard about Refress hair darkening shampoo from a colleague. She said it worked within a few weeks. I, of course, didn't believe her. That’s when she suddenly stood up and grabbed the Refress Hair Darkening Shampoo Bar.

She said she tried a few things but that Refress was the only brand that she felt like actually delivered. She had been raving about how it helped to darken her hair naturally, without using any harsh chemicals. Though I was skeptical, but then she showed me her before and after photos, and I was amazed. Week by week, I could see her hair getting healthier and darker.

I begged her to let me borrow her Hair Darkening Shampoo Bar, but instead she told me to buy my own like a real adult LOL. Thankfully, she gave me the link with a SALE, and I ordered two bars immediately.


I received the package four days later and used as instructed. Wet the bar and rub the lather into your hair. Super simple. 

And of course, I looked into the mirror and expected immediate results, but with products like these you got to use them everyday for about three weeks before you notice anything. In the meantime, I wanted to know what made Refress Darkening Shampoo Bar do what it did. 

It’s all about what CAUSES gray hair. Refress says there’s two reasons,

1. As you age, the melanocytes in your hair responsible for producing pigment begin to decrease, causing the color to fade away.

2. The release of norepinephrine into the follicle due to stress can result in the rapid killing of melanocytes, ultimately ending the production of pigment.

Refress works to safeguard melanocytes and promote pigment production. This means that even in times of stress, your hair can still maintain its natural color and remain healthy. And isn’t that in of itself a great relief? 


Refress includes a blend of three unique ingredients that assist in safeguarding melanocytes and promoting the production of pigments:

Panax Ginseng Root Extract

This is your all-around bad ass ingredient to help make your hair stronger and healthier with a mix of anti-oxidants and peptides. It also is the main force in protecting your melanocytes.

Polygonum multiflorum

Polygonum is amazing for promoting hair growth, restoring hair color, and improving hair texture. 

Butyrospermum Parkii

It effectively nourishes and moisturizes the hair, leaving it with a healthy and hydrated appearance.  

Did It Finally Work?

After patiently waiting for 4 weeks, I was eager to see if the product had made a difference and to my surprise, the areas of my hair that were gray turned darker and even started to regain my original hair color. Moreover, my hair appeared more voluminous and resilient than it had in a long time, and I was astounded by how amazing it looked and felt.

After seeing the amazing results of using Hair Darkening Shampoo Bar, I strongly recommend giving it a try and experiencing the benefits for yourself.
