7 Harmful Chemicals in Shampoos That Cause Hair Loss

Hair is precious and no one wants to lose them to harmful chemicals present in shampoos and hair products.  Dermatologists across the globe believe that witnessing a lot of hair strands in the shower should - amongst other things - make us look critically at our hair product choices. If this warning is ignored, the hair fall can become so chronic that you will need a toupee wig for men or hair wigs for women to cover it!


It is quite normal to lose 50 to 100 hair strands a day but more than that means something is wrong. And a lot of times, it’s the chemicals in our shampoos and hair products that start hair fall. In this blog, Lordhair will help you identify chemicals present in shampoos leading to hair damage that can evolve to full-blown baldness. 

Let’s start!

Is your shampoo causing hair loss?

Shampoo, believe it or not, is often the root (excuse the pun) of hair loss. There is, of course, a certain irony there. The product that we use to clean our hair and make it look better could actually be what causes our hair to fall out. If you were to look at the list of ingredients on the back of a shampoo bottle, then, many of the ingredients would not mean much to you. But, the truth is, in amongst this list are chemicals that cause hair loss. You will find these chemicals in other hair products too. If shampoo was made purely to clean your hair, then perhaps there would not be so much of a problem.

However, as we will outline there are several chemicals in shampoo that cause hair loss that you should be wary of. When you learn what other types of products these chemicals are found in, you will understand why they can be so harmful to your hair.


Below are 7 harmful chemicals found in shampoo that causes hair loss.

Sodium Lauryl Sulfate and Laureth Sulfate

Sulfates are the most damaging of all chemicals found in hair products. Sulfates are actually found in car wash soap and engine degreasers. There are many kinds of sulfates but two that you must be aware of are sodium lauryl sulfates and sodium laureth sulfates.

Think of any shampoo commercial and you will see the actor working up a good lather of shampoo in the shower. Naturally, you would draw the conclusion that lather and foam would be a good thing but that is not really the case.

They break down the proteins our hair needs to grow and they strip away the protective oils of hair which can cause the hair to dry out and then breakage.

Chemical Fragrances

A deciding factor for many of us in the purchase of any shampoo is its scent. Isn’t your first instinct to pick up a bottle of shampoo and smell it? Shampoo, like other beauty products, contains chemical fragrances. They may smell nice but these fragrances can actually cause a hormonal imbalance. Hair loss has been proven to arise from changes in hormone levels.

So, the next time you decide to buy a shampoo just because it smells nice, think twice! Strong chemical fragrances can lead to a lot of hair damage.

Sodium Chloride

Salt may be good for our immune system, but it’s definitely not good for your hair health. It is agreed in the scientific community that its chemical composition adversely affects hair health. Check your shampoo ingredients to make sure that it is not overdosing on sodium chloride. In case you think selecting a chemical-free shampoo is too much work, well, be prepared to wear hair wigs for men

Salt may be good for our immune system, but it’s definitely not good for your hair health. Its chemical composition leads to degrading your hair health.



Shampoo contains preservatives of which parabens are one. Parabens may present the onset of bacteria in hair products but look out for words ending in – parabens such as methylparaben and propylparaben in the ingredients list. They are similar to fragrances because of the effect they can have on a person’s hormones. Parabens are actually also linked to breast cancer.

Have you ever imagined that your favourite hair product is a potential carrier of cancer? Well, you must have by now!

Propylene Glycol

Propylene Glycol has been classified as a skin irritant. Whilst it helps with consistency of shampoo, propylene glycol is used to help the scalp absorb other chemicals in shampoo. So, we are talking about a substance that works to get all the nasty stuff into your body!

Imagine, if it can ruin your hair’s health from outside, what will it do after entering your skin? These chemicals are toxic and cause much more than hair loss.

Diethanolamine (DEA) and Triethanolamine (TEA)

Diethanolamine and Triethanolamine are two chemicals that also cause irritation to the skin. They can also destroy keratin - a key component of hair. This ultimately leads to dry, brittle hair.

Since women shampoo their hair more often and use a variety of hair products, it is more important for them to check the ingredients and make sure that no harmful chemicals are present in their products.

So, there you have it!

A list of harmful chemicals in hair products that can cause hair loss! If you value your hair, then do take the time to check out what is listed on the bottle of your shampoo. There are alternatives out there for sure. All-natural solutions such as apple cider vinegar do exist, for example.


Harmful chemicals present in low quality hair products not only affect your hair and scalp but can also harm your hair system, or human hair wig, if you wear one!
