5 Harmful or Toxic Ingredients in Shampoo

Toxic ingredients in shampoo?

So not chic!

But did you know some of your favourite products might be packed full of chemicals and toxins that are seriously harming your hair?

The list of no-no's when it comes to your hair is huge and sometimes daunting.

So to help you navigate the Parve's from the Parabens, I've rounded up 5 toxic ingredients in shampoos you should be avoiding.

1. Parabens

When it comes to toxic ingredients in shampoo, these are the biggest baddies out there.

Why are parabens bad for your hair?

From scalp irritation and itching to brittle and dry hair, colour fading, and even hair loss; parabens are pretty much nothing but bad news.

What are parabens?

Put simply; a paraben is a preservative used in most shampoos. It is designed to extend the lifespan of your products while preventing the growth of mould and bacteria.

You have probably read this word on the back of your shampoo bottles and not thought much of it. 

And, while I'm sure parabens do their job, they also do a whole lot of nasty things to your hair too.

They cause a hoard of hair problems and should be stripped from your hair care routine ASAP.

2. Alcohol

Alcohol is used in almost all hair care products for its evaporative and cleaning properties.

Why is alcohol bad for your hair?

Certain alcohols, known as short chains, i.e., SD Alcohol 40, Ethanol, Propyl, Propanol and Isopropyl, seriously dehydrate your strands.

So, it turns out alcohol isn't just bad for making you text your ex and ruining your life, but it is also very bad for you..

In fact, it should be kept out of your shampoo at all costs.

Think of it like a permanent hangover for your hair!

But instead of eating a whole pizza or two and camping out on the couch, your hair becomes dry, brittle and breaks.

Over time this causes some serious thinning and hair loss.

So, keep the alcohol in the cocktails and out of your hair.

3. Triclosan

Triclosan is another preservative added to your products to help fight bacteria.

Sounds great, right?


Why is Triclosan bad for your hair?

Triclosan is seriously bad for your strands and your health in general

There is little to no proven benefits of adding triclosan to haircare products and several proven facts to the contrary.

As well as being a skin irritant that causes scalp inflammation, this toxic ingredient in shampoo is also a carcinogen and endocrine disrupter.

It has been linked to hair loss and immune issues, severe weight loss, and under-controlled cellular reproduction.

This means it can make your hair snap and brake faster and grow back slower. It's the recipe for hair thinning.

That's a massive no from me.

4. Dimethicone

Dimethicone is one of the ingredients that make your hair feel smooth.

Your hair might feel softer, but you're doing more harm than good.

What is Dimethicone, and why is it bad for your hair?

This toxic ingredient found in shampoo is a synthetic polymer.

It is a harmful form of silicone that is responsible for giving your strands a false sense of smoothness.

But don't be fooled.

Dimethicone is used in most shampoos because its cheap, but that's the only decent thing about it.

Not only does it irritate your scalp, but it also builds up in your hair over time, making it greasier and heavier.

So that instant soft feeling is short-lived and not worth the cheap price tag.

5. Polyethylene Glycol


What is Polyethylene Glycol and how does it damage your hair?

Polyethylene Glycol is a common thickening agent found in most shampoos.

And while having thicker hair sounds great, I assure you there are easier, safer and more effective ways to make this happen.

This mouthful of a chemical is even more full of harm to your hair. 

This toxic ingredient found in most shampoos doesn't just hurt your hair; it can harm your body too.

It strips your strands of their natural moisturiser, causing them to dehydrate and break.

So, if you're using it to get thicker hair, it will actually have the opposite effect.

Not only that, it is known to interfere with human development so, if you're growing a human or still a growing human yourself, it is a massive no.
