At the time of this writing, this shampoo is Number One in the Top 10 List of Best Selling Shampoos for Hair Loss as of March 2018. This Hair Growth Stimulating Shampoo for men and women is a product by PureBiology, and we’ll be taking a closer look at why it seemingly flew up the ranks on Amazon, bypassed other well-known hair loss/hair growth shampoos, and has claimed the Number One spot in these last few weeks.

We will be reviewing this shampoo for some key ingredients that we have learned are necessary to help stop Dihydrotestosterone (DHT), the hormone that actually shrinks hair follicles, help to nourish and stimulate hair follicles, help to strengthen hair, and actually get it growing again. We will also look for any other ingredients that we have learned are not very beneficial and will likely not help matters for those wishing to do no further harm to their hair follicles.

Here are some of the key ingredients that we look for in a hair loss/growth shampoo. We have determined these key ingredients to be the “Best” for those experiencing thinning hair and hair loss.

If this shampoo checks off all of our requirements, we will not hesitate to recommend it and will update our “Best Hair Loss Shampoos” list.

The Company: PureBiology

But, first things first. Just who is “PureBiology?” This company is fairly new, and according to Trademarks applications, this company recently filed for Trademark protection. This company does have other products listed, and for the most part, they already offer products that have to do with anti-wrinkle creams and lotions. They also have a lash growth serum. With this newer product, however, they have officially entered the hair loss/hair growth billion dollar market.

Unfortunately, however, the reason why it flew to the top spot on Amazon may be clouded with doubt. According to another site we checked, some of the reviews may not be genuine. While this possibility may not reflect on the actual quality of the product, disingenuine reviews can cause harm to the brand when blog sites like the one you’re on shares this information with readers and, basically, calls them out.  In short, just because the company may have found a way to “game” the system in Amazon reviews, and the product is then dubbed a “Top Seller,” does not mean the product is one of the best. Top sellers, or those that are listed in our Top Sellers List, listed above, no matter what marketplace, are not necessarily a “Best of” product. In fact, quite the opposite – in my book anyway.

Discussion & Review:

Looking over the ingredients of this new Shampoo, it really is packed with quite a few beneficial ingredients and one that it could have done without. Let’s discuss some of the beneficial ingredients first.

Pros: This product has a variety of Base Oils and numerous Essential Oils all of which nourish and stimulate hair follicles. The Lemongrass Oil, Tea Leaf Extract, and Rosemary Leaf Oil act as vasodilators, hair follicle stimulants, while the Biotin, Keratin, and assorted Proteins bind to the hair to make it stronger. The Polysorbate acts as another stimulant and cleansing agent while helping to block DHT along with the Saw Palmetto. Even the Glycerin is a gentle cleaning agent, and it is Paraben-Free. Another huge plus is that this product is also GMO-Free. Therefore, all of the boxes in our Table have checked off with the exception of one which is discussed next.

Cons: What’s not so good is the Sodium Laureth Sulfate (SLES) ingredient. Although this is the milder version of Sodium Laurel Sulfate (SLS), a harsher cleaning agent that is historically included in shampoo, it is still a sulfate – meaning it’s a “harsher” detergent when compared to newer milder cleaning agents. Many hair loss/ hair growth shampoos are eliminating any version of the (SLS) harsh cleanser along with its milder versions in order to appease those who either shampoo daily or color their hair. This ingredient is the only negative that I can see. Otherwise, if it were entirely “Sulfate-Free,” this shampoo would be rated as one of the Best – on this website anyway, and it would have been added to our Best Shampoos for Hair Loss – despite questionable or authentic reviews.

And, speaking of reviews, let’s see what they have to say.

What Do The Reviews Say:

Well, what can I say? The reviews are literally “all over the map.” They range from “this works,” to “it’s crap,” and many reviews on Amazon are even questioning the authenticity of other reviews… which is comical, actually. Seeing that this company has, seemingly, gamed the review system with this product and a number of their other products which makes their reviews questionable, I will leave it at that. If you wish to read the reviews on Amazon yourself, you are quite welcome. They appear at the bottom of the product listing.


My overall thoughts on this product are affected by the questionable reviews on Amazon, and this does affect my thoughts about this product and this review. Reviews are “supposed” to be honest and true, and provide an overall snapshot of a particular product. Knowing that they may have gamed the Amazon Review system bothers me. I mean, I’m blogging on my site whose mission it is to “help very real people who are losing their hair,” and, I do read reviews to do just that. I do read them because I can then provide a summary snapshot for my readers who a.) may not have time to read through all the reviews themselves, b.) may not want to read all the reviews themselves, and/or c.) may trust me enough to read my summary review and trust my conclusion. In fact, I take pride in knowing I’m providing a valuable and time-consuming service for others, and so, I’m more than a little bit miffed to realize that this company, and likely others, may have found a way to game the (Amazon) review system.

Heck, it’s even bothering other people who left reviews – after purchasing the product themselves. As mentioned, this product came out of “no-where” and shot up in the ranks on Amazon. Once there, of course, other people see that it’s the “top seller,” and purchase the “top seller” just because it is the “top seller” – which then adds to their “best-selling spot” at the top. With this stated, I’ll now move on to the next point I’d like to make about this product.

After looking at the list of ingredients, and comparing them to the ingredients that we look for when searching for the “Best Hair Loss Shampoo,” this particular product falls just shy of hitting all the beneficial ingredients and features. This product does contain a milder version of a harsh detergent. This ingredient is not as irritating as the stronger version, but, nonetheless, it’s still a sulfate that a hair loss shampoo can do without. Consequently, this product is not recommended for daily use or for those who color their hair – if they want to keep their color for as long as possible. If, however, you do not shampoo daily and do not color your hair, you may give this product a try. Just remember, that using this type of shampoo, with the stimulating oils and other vasodilator ingredients, will result in short-term hair loss, but short-term hair loss will eventually stop to allow for stronger and fuller hair growth.

For these reasons outlined above, this product will not be added to our Best Shampoos for Hair Loss list. Here is the final score:
