Hair Straightening Cream Side Effects

If you’ve been considering straightening your hair using creams, then you should know some of the hair straightening cream side effects.

Many people assume that creams provide a safer alternative solution to salon treatments that not only tend to cost more but could also damage your hair. 

But how accurate are these assumptions? Do creams not have side effects?

While it may be true that these creams have fewer side effects than other straightening methods, they too have some adverse effects on your hair and health.

Let’s look at some of these before you start applying such hair straightener cream.

1. Alters the Hair Texture

The chemical agents present in a hair straightening cream [1] are designed to change your hair’s structure and give it a smooth, sleek, straight appearance.

To do so, these components alter the core architecture of your hair strands and reshape them from the inside.

This alteration can potentially change the pattern of your hair negatively permanently [2].

You might completely lose the original, authentic texture of your hair, making them look deformed and unflattering.

When this happens, no hair care remedies, hair treatments, and conditioning masks can help you bring back your naturally healthy strands.

The only option you would be left with is to grow your natural hair entirely and gradually cut out the straightened sections to revive your hair’s previous healthy state.

2. Causes Severe Hair Fall

The most common and noticeable side effect of using this product is severe hair fall [3].

While smoothing out the hair cuticles for a straighter outlook, these creams also soften the roots and affect the scalp, which results in excessive hair fall and hair thinning.

When you use a hot flat iron on the smoothened hair follicles to maintain a straighter outlook, the heat weakens them even more, causing additional hair breakage and hair loss.

This condition worsens when you don’t choose the suitable cream or follow the proper straightening solution steps.

3. Starts to Produce Split Ends

In addition to potentially causing extensive hair loss, they could also result in severe split ends.

Because these creams leave your hair dry and brittle and make the follicles soft and weak, the hair strands tend to break from the middle at the slightest inconvenience.

Which results in severe split ends. And when this occurs, your straightened hair looks un-uniform and unsightly.

4. Results in Itchy Scalp

Itchy Scalp

Since hair straightening creams are made up of different chemical components, it reduces the production of natural oils in the scalp that keeps it hydrated and healthy.

Because of a lack of oils and nourishment, your scalp becomes dry flaky and causes itchy scalp and dandruff problems.

Severe dandruff [4] often spreads to the neck and forehead and leads to severe fungal infection.

Another cause of an itchy scalp is the allergic reaction to the cream. You could be allergic to any of the numerous chemicals used in hair straightening creams and not know about it.

Once you apply it to your hair, the allergic reaction can manifest immediately, causing unbearable irritation on your scalp and your skin.

This irritation can gradually lead to rashes and redness, and you might need to seek medical help.

5. Has the Potential to Cause Cancer

Many hair straightening creams available in the market contain a chemical ingredient called Formaldehyde.

Formaldehyde is a potent, colorless gas that removes annoying frizz and flyaways from hair strands and helps to keep them smooth and straight for an extended period.

But according to the U.S. Environmental Protection Agency(EPA), this component is hazardous to the human body and should not be used in any form or shape.

It can cause cancer (or help cancer grow and spread) if you are exposed to it for a long time.

Aside from the person who uses the straightening cream, the surrounding people also risk suffering from cancer and other health hazards.

6. Imposes the Risk of Health Problems And Allergic Reactions

Aside from being a carcinogen (a component that might cause cancer), formaldehyde in hair straightening creams is responsible for triggering other health problems and allergic reactions, from itchy scalp to skin rash, sneezing, coughing, and running nose.

This component can cause extreme discomfort.

    How can a mere hair straightening cream cause deadly cancer? Are you sure about the facts or are you just saying this to keep people from straightening hair? I am really confused.

    I used the straightening cream a few months back to straighten my manes. And I just can explain what I went through after that. The side effects and the reactions were so bad that I had to go bald to maintain my health.

    I thank you guys for such an amazing article. It will help many girls out there.
