Chemicals That Lower Testosterone In Shampoo

In this article we are going to look at the chemicals that lower testosterone found in shampoo products. The reason these chemicals lead to lowered testosterone is they behave or enable endocrine disruptors to enter the body. If you’re not sure what endocrine disruptors are, I advise you take a look at my article on Chemicals That Lower Testosterone – Where Are They Found – It will help you gain an understanding of endocrine disruptors.

To give you a basic overview, endocrine disruptors negatively impact your hormone production. They disrupt your hormones balance including lowering your testosterone production, this can lead to a number of health issues, even potentially cancer so that is why these chemicals are an issue.

What Shampoo Products/ Brands Contain Chemicals That Lower Testosterone?

Just as we covered in my shower gels article which you can see here: Chemicals That Lower Testosterone In Shower Gel – The quick answer is that most commercially available shampoo products and brands contain these chemicals. Again much like shower gels, the usual exception to this is where products are advertised as organic, natural, SLS free, parabens free or toxic chemicals free. If the brand/ product isn’t promoted as this, chance is that it contains chemicals that lower testosterone and unfortunately most shampoo products do contain these chemicals.

What Are the Chemicals Found In Shampoo That Lower Testosterone

You probably will have noticed above I’ve mentioned a few terms you may not have heard of before such as SLS, parabens etc. these are in fact some chemicals that lower testosterone, we are going to be covering them in greater detail below, so hopefully the answer to all of your questions will be revealed.

The main chemicals that lower testosterone found in shampoos are sulfates, parabens, phthalates & the chemicals from the plastic packaging. We will cover what these chemicals are and how they lead to lowered testosterone production.

Sodium Lauryl/Laureth Sulfate (SLS/SLES) Sulfates

Sodium lauryl sulfate is a detergent, surfacant & emulsifier. It’s used as an ingredient in thousands of industrial cleaners, cosmetic products and body cleaning products which of course includes shampoos. It is sometimes abbreviated to SLS/ SLES, you may also see it appear as …sulfate. So if you see an ingredient with sulfate as part of it, remember to avoid!

So in regard to SLS a number of people actually mistake it as being healthy/ safe as it originates from coconuts; but it is the manufacturing process that it goes through that results in it becoming toxic and a danger to your endocrine system and testosterone production.

From an endocrine/ testosterone production and your wider health, the issue is that SLS breaks down the skins’ moisture barrier. This allows dangerous chemicals & substances like the ones listed below to penetrate the skin. In fact the effect is so extreme that SLS is thought to make the skin 100 times easier to penetrate. woman in shower

Another major issue is that when SLS combines with other chemicals it becomes a “nitrosamine”. This is a very strong type of carcinogen, this is a poison to the body. Studies in to the effects of SLS exposure have shown links to skin & eye irritation, organ toxicity, reproductive & developmental toxicity & the key reason you are reading this article, reduced testosterone production/ endocrine disruption. This hopefully highlights why Sodium Lauryl Sulfate or any sulfates are one of the chemicals that lowers testosterone and needs to be avoided for healthy testosterone production and improved wider health!


Parabens are widely used as preservatives in thousands & thousands of skin care & cosmetics products, this of course includes shampoos. The major issue with parabens is they behave like estrogen & are an endocrine disruptor. As we’ve covered above an endocrine disruptor stops your body producing hormones effectively and this often leads to a decrease in testosterone production. In research, it has been shown that parabens can have the same effect on the body as estrogen, they can cause a decrease in muscle mass, an increase fat storage and cause the development of male breast growth/ moobs.

The United States Environmental Protection Agency has also conducted research linking methyl parabens to metabolic, hormonal, developmental & neurological disorders. So parabens don’t just lower testosterone; but research suggests they are a threat to several areas of your health!


Pronounced as thal-ates, these are an endocrine-disrupting chemical that you don’t see directly listed on a cosmetic’s ingredients list. Phthalates differ to parabens as they don’t mimic estrogen, instead studies have shown negative effects on the male reproductive system, this includes testicular cell destruction, decreased sperm count and thyroid irregularities. Destruction of testicular cells and thyroid irregularities are what cause the real issue as far as testosterone production is concerned, as the testes & your thyroid is where testosterone & hormones are produced.

So How Do We Avoid Phthalates

As I mentioned above, these aren’t directly listed on ingredients in products, so the main thing to look out for is synthetic fragrance. “Fragrance” or “pafum” is potentially the vaguely listed ingredient in existence. As fragrance in the legal sense is considered “proprietary,” companies do not have to disclose its components. Sadly, this is how chemicals that lower Stop Signtestosterone like phthalates are snuck in.

Plastic Packaging & Microbeads

The problem with plastic packaging is that it can leach harmful chemicals into the material it contains, the same goes for the plastic micro beads that you sometimes see added to products (albeit more shower gels & facial scrubs as supposed to shampoos). One of the chemicals which you may have heard of is BPA (Bisphenol-A), this is getting a lot of coverage in the media at present & is a widely recognized endocrine-disrupting chemical and xenoestrogen. It doesn’t just end with BPA though as there are other chemicals found in plastics with similar effects, so still something to be wary of if plastics are advertised as “BPA Free”

If you aren’t familiar with the term xenoestrogen, it is a hormone-mimicking chemical in humans and animals, as you may be able to guess from the name xenoestrogen, the hormone that it specifically imitates is estrogen. As we know estrogen is the opposite of testosterone, so we really don’t want additional estrogen synthetically being added to our bodies!

Then on top of this in regard to BPA, environmental scientists have noted the detrimental effect it has on our oceans & wildlife. So it isn’t just your health that plastics negatively effect; but they also destroy the surrounding environment, this is part the reason you may hear about how fish are now mostly plastic, due to ingesting so much of it, which again puts the chemicals back in to your body!


While this won’t be listed as an ingredient, due to the rise of natural beauty products we need to be aware of the types of plants used in our cosmetics and how they’re harvested. Specifically, neurotoxic organophosphate compounds there were actually developed by the Nazis as a nerve gas to aggressively attack the human nervous system. This same chemical has been adapted for pesticides, this chemical also acts as an endocrine disruptor. In order to avoid this chemical, I advise to check that botanical ingredients are organic/ grown without pesticides) or biodynamic-organic.

As I’m sure you can tell from the above, a combination of SLS and any of these other chemicals potentially found in shampoo is a risk to your wider health; but especially your testosterone production & hormone balance. These are the main reasons why most commercial shampoo products can cause lowered testosterone production. If you need an overview of the health risks associated with low testosterone, I advise you have a quick look at this Health And Testosterone Article.

There are other chemicals found in shampoos that negatively impact your health in multiple ways. So I’d advise to keep an eye out for the following & avoiding where possible:

  • Dioxane
  • Propylene glycol
  • Triclosan
  • Diethanolamine or DEA

How To Know If Your Shampoo Contains These Chemicals

My first go to is looking to see if the brand promote themselves either organic, paraben & SLS free or free of toxic chemicals. Magnifying GlassAs this topic has been gaining a fair bit of attention from the media, brands are usually proud to announce they don’t contain these chemicals that lower testosterone. I do still suggest double checking the ingredients, this is where the back of the packaging and google become your friend! With a lot of larger companies, you can even go on to their site and ask them questions directly on “live chat” type functions.

Alternative Product Options

As I’ve mentioned in this article a few times, the shampoo brands that you need to be looking at should be paraben & SLS free, organic or free of toxic chemicals. There are a couple of different brands that I use and can recommend, which you can see in this Things That Lower Testosterone – Product Alternatives

    1. Hi Sujandar,

      I’m glad you found this article useful, sadly most major shampoo brand and those easily available do contain these chemicals that lower testosterone and cause other health issues.

  4. That is the last thing I need is lower testosterone. I’m over 40 and there is a decrease in testosterone anyway for men my age. I don’t need it made worse because of my shampoo. Thank you for this article. I will now go and check what chemicals there are in my shampoo and if there are SLS or parabens in it I will find a different brand to wash my hair with.

    1. Hi Cory,

      Good to hear that you found this article useful. yes your testosterone does start to lower naturally after you hit the age of about 30. Yeah lowered testosterone means lowered muscle mass amongst many other health issues, which you can see more about here: Testosterone And Health – How Low T Effects Male Health – Check out the comment above to see the page to go to, to see alternative brands that don’t contain these chemicals.

  5. It is really sad because not a lot of people that make use of shampoo know about these chemicals and unfortunately the population making use of shampoo is so much. 

    I have to say that I have learned a lot from this post because I had no idea about the chemicals listed in this post that are found in shampoo. I don’t even bother to look at the label of the shampoo I buy and who knows how this has affected me. I really hope that I have not been affected by this.

    Next time I buy shampoo I am going to look at the label of the shampoo I normally buy to see if it contains any of these listed chemicals.

    1. Hi Jay, 

      I’m glad you found this article useful!

      Yeah I did exactly the same thing before and never looked at skin care item labels, it was only when I came to learn about endocrine disruptors, that I realised these chemicals that lower testosterone production are found in most shampoo and skin care brands. Yeah the effects can be reversed by reducing your exposure to these chemicals, if you want to reduce your exposure to these chemicals that lower T, check out this article on Chemicals That Lower Testosterone – Where Are They Found?

  6. What an interesting read this was for me. Thanks for this informative article. Probably the last thing I need right now is to lower level of testosterone for me. Its often a thing of wonders these days getting to know that all these shampoo are containing this harmful chemicals for men. I guess I need to look out for SLS or parabens before making any shampoo purchase. It isn’t sensible for me to waste my cash on what’s harmful to my health. Thanks for this but then, is it harmful to women too so I can know if I should tell it to my wife too.

    1. Hi RoDarricik,

      I’m glad you foudn this article useful!

      Yes these endocrine disrupting chemicals negatively impact both male and female health. The effects are more pronounced as males as some of these chemicals double up as estrogen imitators but endocrine disruption causes health issues for everybody as it ruins both make and female hormone profiles.

  7. That’s very interesting write up, most of us everyday people wouldn’t give this a thought. How is it that when harmful chemical’s like these continue to be aloud in production.?

    I have been looking a lot into organic products, now I think the decision is made for shampoo’s etc.

    Thanks a bunch. Rob

    1. Hi Rob, 

      Yeah it’s terrible that these chemicals that lower testosterone and are endocrine disruptors are even allowed in our products in the first place. More of them are getting banned; but as they have cleaning properties, the toxic nature appears to just be overlooked. Yeah I agree organic is the way to go, as I’ve mentioned there are multiple products that contain these toxic chemicals, check out this article on Chemicals That Lower Testosterone – Where Are They Found? to get an idea of what products you need to avoid and swap out for non toxic/ organic options.

  8. What an insightful article. I never knew that there were chemicals in shampoo that could affect the testosterone levels or influence the endocrine production. It is quite scary what is and can be put into everyday products like shampoo, without the general public being aware of the negative effects. Thank you for pointing it out and it I will certainly be checking the ingredients list far more closely.
