7 Most Harmful Hair Product Ingredients You Need to Avoid

That hair product could be sitting pretty on a store’s shelf screaming “pick me! pick me!”, but, should you really buy a hair product for its looks only? No. Definitely not. You should take a minute to scan through its label first to make sure there are no harmful hair product ingredients!

If you spend hours scrolling through Instagram, Pinterest, and YouTube looking for the perfect haircare products to create the beautiful hair of your dreams, you should know that some of these products may be doing more harm than good to your precious hair.

That’s correct, folks! Several haircare products contain dangerous substances that can cause dryness, breakage, and even hair loss! But don’t get too worked up.

Importance of knowing what’s in your hair products

When it comes to hair products, it’s easy to get caught up in the hype of fancy packaging and marketing claims. What matters most is knowing what’s inside those bottles and tubes. Your hair is a delicate part of your body that deserves to be handled with care. That is why it is critical to understand what is in your hair products and avoid dangerous compounds that might destroy your hair.

Certain popular components in hair products can deplete your hair of its natural oils, causing dryness and breakage. Others may cause scalp irritation, resulting in dandruff or other problems. By reading the ingredient list, you can identify these potentially dangerous compounds and avoid them.

But knowing what’s in your hair products might help you select the correct ones for your individual hair type and needs, not just avoid undesirable substances. If you have fine hair, for example, you should search for items that are lightweight and won’t weigh it down. If you have curly hair, you should look for products that add moisture and help define your curls.

We get it, life can get pretty busy, and reading ingredient labels might be the last thing on your mind when you’re in a rush to get ready in the morning. But trust us, folks, taking a few extra seconds to check what’s in your hair products can make all the difference.

The 7 Harmful Hair Product Ingredients

We’ve made a list of the seven most dangerous hair product chemicals to avoid. So grab a pen and paper, take some notes, and let’s embark on the journey to healthier, happier hair!

1. Parabens 

Parabens are a group of synthetic preservatives that are widely included in shampoos, conditioners, and styling products. They are used to keep microorganisms at bay and to extend the life of these products. Nonetheless, parabens have been the source of significant debate in recent years due to their potential for harm.

Why is it Harmful

Because parabens can imitate the hormone estrogen in the body, they have been linked to hormone disturbance, particularly in women. This disturbance has been linked to an increased risk of breast cancer and fertility problems.

While some studies claim that the amount of parabens present in hair products is too low to cause harm, others contend that the cumulative effect of exposure to several paraben-containing products can have a major influence on general health like cancer.

Better Alternatives

• Paraben-free hair products use natural preservatives like vitamin E, rosemary extract or grapefruit seed extract, which can be utilized to extend the shelf life of hair products without having to worry about parabens’ potentially hazardous effects.
• Products that use alternative preservatives like phenoxyethanol, sodium benzoate, or potassium sorbate have been demonstrated to be safer than parabens.

What to look out for

While shopping for hair products:

• Look for hair products that are labeled paraben-free
• Check the ingredient list for parabens like methylparaben, ethylparaben, or propylparaben

2. Sulfates

Sulfates are a type of harsh detergent that is typically present in hair care products including shampoos and cleansers. They are used to lather the hair and remove dirt and grease from it.

Why it is harmful

Sulfates can deplete the hair’s natural oils, causing dryness and breakage. They can also cause irritation and flaking on the scalp. For those who have color-treated hair, sulfates might cause the color to fade faster, resulting in a reduced color lifespan.

Sulfates should also be avoided by persons with curly or wavy hair since they might disturb the natural curl pattern and cause frizz.

Better Alternatives

• Sulfate-free shampoos and conditioners, which use milder cleansing agents like coco-betaine or sodium lauryl sulfoacetate (SLSA)
• Co-washing, or using a conditioner instead of shampoo, which can help retain natural oils in the hair

These alternative components may also be softer on the scalp and more suitable for people with sensitive skin.

What to look out for

While shopping for hair products:

• Look for shampoos and conditioners that are labeled sulfate-free
• Check the ingredient list for sulfates like sodium lauryl sulfate (SLS) or sodium laureth sulfate (SLES)

3. Phthalates 

Phthalates are a class of synthetic compounds that are typically found in hairsprays, gels, and mousses. They are used to give the hair hold and fragrance.

Why it is harmful

Phthalates have been related to hormone imbalance, reproductive problems, and even cancer. They can also cause hair damage over time, resulting in dryness, breakage, and thinning.

Better Alternatives

• Phthalate-free hair products, which use natural fragrances and ingredients to provide a pleasant scent
• Products that use essential oils or plant-based fragrances, which can provide a natural and gentle aroma without harmful chemicals

What to look out for

While shopping for hair products:

• Look for hair products that are labeled phthalate-free
• Check the ingredient list for phthalates like dibutyl phthalate (DBP), dimethyl phthalate (DMP), or diethyl phthalate (DEP)

4. Triclosan

Triclosan is a regularly used antibacterial agent found in many personal care products, including shampoos and conditioners. Although it may appear to be a beneficial substance, triclosan can be detrimental to both hair and overall health.

Why it is harmful

Research has connected triclosan to a variety of health problems, including disruption of hormones, bacterial resistance, and even cancer. In addition, triclosan can cause hair damage by removing its natural oils and causing dryness and breakage.

Better Alternatives

• Triclosan-free hair products, which use natural ingredients like tea tree oil or lavender oil to provide antibacterial and antifungal properties
• Products that use alternative ingredients like zinc pyrithione, which can help soothe an irritated scalp without the risks associated with triclosan.

What to look out for

While purchasing hair products:

• Look for hair products that are labeled triclosan-free
• Check the ingredient list for triclosan, which may also be listed as 5-chloro-2-(2,4-dichlorophenoxy)phenol (DCP)

5. Formaldehyde 

Formaldehyde is a hazardous chemical that has been connected to a variety of health problems, such as respiratory disorders, skin irritation, and even cancer. It is often utilized in hair straightening treatments and other hair products that promise long-lasting benefits.

Formaldehyde works by dissolving the hair’s natural bonds and reforming them in a more straightened structure. Yet, this method can cause serious hair damage, including dryness, brittleness, and breaking. When inhaled or absorbed through the skin, formaldehyde can be damaging to the body as well as the hair.

Why it is harmful

Formaldehyde exposure can result in a variety of health problems, including irritation of the eyes and mouth, respiratory disorders, and even cancer. In some instances, exposure to formaldehyde might result in chronic bronchitis and asthma.

Hair straightening products containing formaldehyde should be handled by professionals as it is known to cause severe irritations to the eyes, nose, and lungs and allergic dermatitis when inhaled or when it comes in contact with your skin.

It is strongly advised to buy a product free of formaldehyde whether it will be handled by professionals or not.

Better Alternatives

• Formaldehyde-free hair products, which use alternative preservatives or natural ingredients like citric acid
• Products that use plant-based ingredients like aloe vera or green tea, which can help soothe and hydrate the hair without harsh chemicals

What to look out for

While purchasing hair products:

• Look for hair products that are labeled formaldehyde-free
• Check the ingredient list for formaldehyde-releasing preservatives like DMDM hydantoin, quaternium-15, or imidazolidinyl urea

List of ingredients to look out for that are prone to release formaldehyde: methylene glycol, DMDM hydantoin, imidazolidinyl urea, diazolidinyl urea, quaternium 15, bronopol, 5-bromo-5-nitro-1,3 dioxane, and hydroxymethylglycinate. 

6. DEA/MEA

The chemicals DEA (diethanolamine) and MEA (monoethanolamine) are widely found in shampoos and conditioners. They are utilized to create a rich lather and boost the product’s efficacy. Nonetheless, they can be exceedingly damaging to the hair and the body as a whole.

Why it is harmful

DEA and MEA can irritate the skin, eyes, and respiratory tract, resulting in allergic responses, asthma, and even cancer. In addition, they can cause hair to become dry, brittle, and thin over time.

Better Alternatives

• DEA/MEA-free hair products, which use alternative emulsifiers and surfactants like cetearyl alcohol or cocamidopropyl betaine
• Products that use natural ingredients like coconut oil or shea butter, which can help provide moisture and nourishment without harsh chemicals

What to look out for

When purchasing hair products:

• Look for hair products that are labeled DEA/MEA-free
• Check the ingredient list for DEA (diethanolamine) or MEA (monoethanolamine)

7. Silicones

Silicones are a group of synthetic compounds found in a variety of hair treatments, including conditioners, serums, and styling solutions. They are used to give hair a smooth and silky texture as well as luster. Silicones, on the other hand, can be damaging to hair health in the long run.

Why it is Harmful

Over time, silicones can accumulate on the hair, forming a barrier that prevents moisture from accessing the hair shaft. Dryness, brittleness, and fracture can result from this. Furthermore, silicones are difficult to remove from hair, resulting in a lack of volume and a weighed-down appearance.

Better Alternatives

When it comes to nourishing and shaping the hair, there are better alternatives to silicones.

• Silicone-free hair products, which use natural oils and ingredients to provide similar smoothing and conditioning effects
• Products with water-soluble silicones, which can be easily rinsed out of the hair without causing buildup

Those with fine or thin hair may also benefit from avoiding silicones entirely, as they can weigh down the hair and cause a lack of volume.

What to look out for

While shopping for hair products:

• Look for hair products that are labeled silicone-free
• Check the ingredient list for common silicones like Dimethicone, Cyclomethicone, Phenyl trimethicone, Cyclopentasiloxane, and Cyclohexasiloxane.
