But no matter how useful those tools are, with frequent use it will damage your hair gradually. Most of these hair tools use heat and we all know that heat is one of the greatest enemies for human strands. Heat soaks up all the moisture from hair and makes it dry, damaged and frizzy. It happens more on thick, curly or coarse hairs as these types of hairs tend to take more time to style it.

However, hairdryers and hair straighteners both damage the hair more or less. The question is which one is more damaging? We are going to discuss below about what we have found in our last one month research. Without further ado let’s scroll below.

The Damages - Hair Dryer Vs. Flat Iron

Before using any hot tools for hairstyling, blow-dry the hair is a must. Otherwise, it can damage your hair severely. Air drying or drying your hair naturally is the best option. But if you use a hairdryer, your hairstyling becomes very ease. It saves time and helps you to achieve the desired look you are wishing for.

Everything has its own cost. Even though hair dryer will make the process easier but it will damage the hair in the long run. Because of the heat, the pores in our scalp open up. As a result hair fall increases. It also damages the hair follicles and breaks the hair. It will make the hair frizzy if you use it on a regular basis. After some time you will also lose the natural texture of your hair and left with dull hair without any shine. And when you are not careful enough it can burn the scalp, ear or neck area.

After blow-drying your hair, it comes to the part where you can actually start styling your hair. The flat iron is one of the most popular heat tools for having sleek, straight and many trendy hairstyles. You can create several hairstyles by only using a flat iron. Most girls tend to straighten the hair with a flat iron but it can also create different kinds of curly or wavy hairstyles. It makes the hair sleek and manageable.

Even though for hairstyling, a flat iron is a great tool but not the vigorous one. While using the flat iron your hair can be damaged significantly. By regular using the flat iron your hair can get burnt. It makes the hair fragile and causes breakage. Using flat iron is one of the main reasons for split ends. It draws all the moisture from the hair and makes it dry. Dry hair is a common reason for fizziness. Like the hair dryer flat iron can also cause hair fall, in some cases permanent hair loss. A flat iron can trigger some allergic reaction and cause itchy skin on scalp as well as body.

In a conclusion, if you want a direct answer from us that which one does more harm to our hairs, actually, the answer is both of them. Both the tool uses direct heat on our hairs and the damages are almost same. Some hair expert says flat irons do more damages as most of the people tend to hold the hair straightener in one place and our hairs get direct contact with the hot plates. Thus overuse of flat iron does more damages than blow dryer. But we like to give the two tools a tie this time.

However, you can always have options to minimize the damages. Let’s check below to see how you can reduce the damages.

  1. Hi,

    I rarely use a hairdryer or flat iron to dry or style my hair; maybe once or twice every month. Still, my manes are damaged and look so lifeless. I just never let them loose and sport them proudly because of their luster-less nature.

    I am really worried.

    Should I stop using these tools?

    Please help me here.

    • Dear Tinker Bell,

      Thank you very much for confiding in us. We love to help our readers.

      Using hot tools once or twice a month is okay. Such limited use won’t cause any dreadful damages to your tresses.

      We assume some other factors are causing your hair damage. We would suggest you visit an expert as soon as possible to identify the root of the problem and care for your hair accordingly.

      We hope we could help.

  2. Holy crap!

    After going through this article I feel like throwing all my hair styling tools. I never knew these tools were so damaging for my precious hair locks.

    Then again, all my heated styling tools are super expensive and come from well-known brands. I don’t want to throw them away.

    What should I do?

    Really in need of some expert opinion!

    • Dear Patricia,

      We are sorry to hear that you are worried about your hair as well as the styling tools.

      You don’t need to throw out all your head styling dryers and irons. What you can do is limit the usage of these tools and never forget to apply a liberal amount of heat protectant before putting heat to your delicate hair strands to protect them from burns and damages.

      We hope this would help you.

  3. Hello there,

    I read somewhere that a concentrator nozzle attached to the blow dryer helps to limit the heat damage. Is it true? And to what extent this statement is true?

    Thank you for reading this.

    I would appreciate it if you answer.

    • Dear Janet,

      What you read is not true. A concentrator nozzle might do many things but it won’t limit heat damages. Putting heat in your hair in any type of form would surely cause damages.

      Don’t believe anything you read on the web.

  4. Hello there,

    In one part of your article, you have mentioned that some materials would save my hair from heat as much as possible. I have fine hair. Can you suggest to me which material should I prefer to style my tresses without any burns?

    This would be really helpful.

    Thanks in advance!

    • Dear Josh,

      To style your delicate fine tresses, try to adopt a hairdryer and flat iron that is made from ceramic material and incorporates ionic technology. The ceramic material generates and delivers very moderate heat which is not at all damaging to the hair strands.

      We hope this would help you.
