Simfort is a brand that makes shampoo for hair loss. The brand claims that their shampoo is the "best hair growth shampoo for men" and that "you don't need to fight genetics" because of their carbonic acid shampoo technology.

But what is carbonic acid and can it really reverse hair loss? Is hair loss caused by a buildup of dirt and grime as Simfort claims? Does Simfort Shampoo contain any unhealthy additive ingredients? And how do real users rate and describe the effects of Simfort Shampoo?

In this article we'll answer all of these questions and more as we analyze the claims made by Simfort about the true cause of hair loss.

We'll also explain what carbonic acid (the active ingredient in Simfort Shampoo) is and whether it can reverse hair loss, as well as review the full ingredient list of the shampoo to see if there are any potentially harmful ingredients.

Finally, we'll share real, unsponsored Simfort Shampoo user reviews.

Does a Dirty Scalp Really Cause Hair Loss?

As shown above, Simfort’s entire premise is that hair loss is caused by hair follicles being “buried under layers of dirt and grime” and creating what they call a “sebum plug.” There are no sources or citations for these claims.

We want to be clear: male pattern baldness is a very well-established biological process reported in thousands of medical studies. It’s not something yet to be uncovered by a shampoo company.

As documented in a 2022 medical review, male pattern baldness is caused by a miniaturization response of hair follicles to dihydrotestosterone (DHT). This is genetically determined, but can be accelerated by lifestyle factors by stress.

We have not come across any medical studies suggesting that "dirt and grime" covering hair follicles is the cause for hair loss, nor any suggesting that Simfort's shampoo does a better job clearing dirt and grime from the scalp than any other shampoo.

Does Carbonic Acid Reverse Hair Loss?

As shown above, the active ingredient in Simfort is carbonic acid.

The brand claims that this compound "helps to unclog the hair pores...and repairs the hair follicles."

However, there's an issue. According to medical research, carbonic acid only exists at room temperature for fractions of a second, so it’s chemically impossible for this to be an active ingredient in a shampoo. This is not a cosmetic ingredient; it’s a chemical compound that immediately dissociates into bicarbonate ions.

In our opinion, it's a major red flag that this company is listing an active ingredient that appears to be impossible to include in a shampoo formulation. Since carbonic acid physically cannot be the active ingredient in this formulation, we have no idea what is instead.

The ingredients list for Simfort shampoo (which we'll review in the next section) does not list carbonic acid at all, making their product page even more confusing.

We actually reviewed another shampoo brand called Fortero that lists carbonic acid as a main ingredient and had similar concerns.

But what other ingredients are in Simfort and are any of them backed by good research? We'll review in the next section.

Simfort Shampoo Ingredient Analysis

The ingredients in Simfort Shampoo are shown above.

There are some ingredients in this formulation which are shown in research studies to improve hair quality.

Hydrolyzed keratin has been clinically shown to improve damaged hair. Keratin is the core structural protein in hair so this makes sense.

Rosemary leaf oil was shown in a clinical trial published in the Phytotherapy Research journal to promote hair growth.

Lemon fruit extract contains a phytonutrient called limonin which was shown in a 2022 clinical trial to signal hair regrowth. This was an in vitro (test tube) trial, so the results are weaker than a trial with human participants, but still promising.

There is one ingredient we consider questionable from a health perspective.

Phenoxyethanol is a synthetic preservative, and as we documented in our Raw Sugar Shampoo reviews article, has been clinically shown to be toxic to human cells.

There are also a few ingredients we can't even identify in this formulation, which is not something that's ever occurred before in our hundreds of product formulation reviews.

"LPG" is the second-listed ingredient but we have no idea what this is referring to or if it's an acronym for something. A Google search for "LPG" returns "liquid petroleum gas" which we would hope is not in a shampoo.

"BG" is also listed as an ingredient and is one we can't identify.

Pros and Cons of Simfort Shampoo

Here are the pros and cons of Simfort as a brand in our opinion:

Pros:

• Contains some effective ingredients

Cons:

• Active ingredient doesn't appear stable at room temp
• Contains a synthetic preservative
• Questionable health claims on brand website
• Contains several ingredients we can't identify
• Expensive
• Relatively negative customer reviews

Conclusion

We do not recommend Simfort Shampoo or any products sold by this brand. This is genuinely one of the strangest brands we've ever reviewed on Illuminate Health.

Simfort claims, without any proof, that hair loss is caused by dirt, grime and sebum plugs. Hair loss is a very well-understood process in scientific literature, and is hormonally-driven. We haven't seen any evidence that it's caused by dirt buildup on the scalp.

Simfort claims that their active ingredient is carbonic acid, but the research we found on this chemical compound states it's only stable at room temperature for fractions of a second, and thus chemically impossible to include in a shampoo formulation.

This shampoo also contains several ingredients that we can't even identify, which is a first in our hundreds of product reviews.

There are a few research-backed ingredients in this shampoo for improving hair quality, but it also contains a synthetic preservative that health-conscious consumers may wish to avoid.
