What Chemicals Cause Hair Loss?

What Chemicals Cause Hair Loss?
Hair loss is a problem that affects both men and women. Men tend to lose their hair as they age, but some people experience sudden hair loss at a young age or even earlier in life. If you are experiencing hair loss, it’s important to identify the cause. It is essential to treat the underlying issue before your hair loss gets out of control. If left untreated, a receding hairline can lead to complete baldness.

There are several reasons behind hair loss including genetics, stress, and hormone imbalances. Some chemicals may also trigger temporary or permanent hair loss in sensitive individuals. In this blog post,GEXWORLDWIDE - a leading hairpiece
toupee brand - will give you information about what chemicals cause hair loss and how they do so. You will also learn about the potential dangers of these chemicals and what you can do if you suspect that they might be leading to hair loss in yourself or someone else you know.

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, GEXWORLDWIDE will help you identify chemicals present in shampoos leading to hair damage that can evolve to full-blown baldness.

What Causes Hair Loss?

Hair loss can be triggered by several different factors, including genetics, poor diet, stress, and hormone imbalances. Hair loss is not always permanent; it’s possible to stop and even reverse your hair loss if you identify the cause. The most common reasons for hair loss include:

Some people, especially men, are more likely to experience hair loss because of their genetics.

Alopecia areata
This is a condition that causes sudden hair loss. It is not known what causes alopecia areata, but it is believed to be an autoimmune disease.

Androgenic alopecia
This is the most common type of hair loss. It is genetic, and it affects men and women.

Hormonal changes
Changes in hormone levels can cause hair loss, especially in women who experience hair loss as part of menopause.

Chronic stress can cause changes in hormone levels that can lead to hair loss.

About 90 percent of our scalp hairs are in the active anagen phase, while the remaining 10 per cent are in the resting telogen phase. The anagen phase, which takes about three years to complete, describes the phase of hair development on our scalp. The telogen stage, which lasts between two and six months after the anagen phase ends, marks the end of the hair-growth cycle. New anagen hairs slowly replace the telogen hair after the telogen phase ends, ending the cycle.

When we are exposed to a stressful situation, our bodies prematurely shift a greater proportion of anagen hairs into the telogen resting phase, resulting in an abnormal amount of hair resting and shedding. Normally, we lose about 100 to 150 hairs a day.

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.

Shampoo Ingredients That Cause Hair Loss

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.

Out of all the harmful chemicals present in popular shampoos (including the ones we discussed above), Formaldehyde is the most damaging. Also called human carcinogen, it has proven to be absorbed through the scalp during animal testing. This common shampoo ingredient is an irritant and an allergen to some people.

While washing your hair with shampoo rich in Formaldehyde, your eyes might sting. In rare cases, your nose will start running. According to leading hair experts, there also have been cases of hair loss and vomiting from hair products with high levels of Formaldehyde. So, watch out for this hair-damaging chemical present in shampoos!


You might be surprised and probably thinking, “Wait, there is alcohol in my shampoo?” To be honest, alcohol is a very common component in cheap shampoos. Although not all alcohols are bad for your hair (like Cetearyl alcohol and Stearyl alcohol), alcohols like isopropanol and propanol present in some popular shampoos can make your hair lifeless and trigger hair loss. Read the shampoo label to make sure these alcohol formulations are not present in your shampoo!

So, there you have it!
