Although the hair dryer is a great invention that many people use today, it might not be all rainbows and sunshine. In fact, many people are scared to use this tool, thinking that it’s causing their hair to fall out more often. But is that the truth? If this question “Can a hair dryer causes hair fall” pops in your head, the answer is that it depends on a lot of factors. Do you use it every day? What temperature are you using when blow-drying? What’s your hair type? Are you using a heat protectant? 

If you have all the answers to these questions, then let’s dive in. I’ll explain why these questions are important in determining whether the cause of your hair fall is due to your hair dryer use.

Do you use it everyday?

Using a hair dryer every day might be a bad idea if your hair is already damaged or you have thin hair. You might want to limit the use of your hair dryer to about twice a week for those who have thin hair. But normally, with the right care and protection, blow-drying every day is not that big of a deal to a lot of people. 

While blow-drying and using other heat styling devices can lead to heat damage and make your hair brittle, it would not lead to a full-blown permanent hair loss. Your hair will still grow after a while.

What temperature are you using?

Another factor you need to consider when blow-drying is the temperature. The right temperature depending on your hair type would be key to limiting the damage to your hair. For example, for thinner hair, we recommend that you use the lowest heat setting possible. This is because thin hair is more prone to heat damage and can lead to breakage and frizz.

For curly hair, while these hair type needs higher heat to be styled properly, we recommend that you use the included diffuser on your hair dryer. Diffusers scatter the hot air on a larger area lessening the chances of heat damage.

What’s your hair type?

As we briefly mentioned in the last section, certain hair types can only tolerate certain levels of heat. Below is the summary of what heat setting you should use depending on your hair type.

Andre Walker gave an excellent guide on how you should treat your hair depending on your hair type. We recommend giving it a read.

Are you using a heat protectant product?

There are a lot of products that are available today to protect your hair from heat damage. These are called heat protectant, to use this you basically just spray it all over your hair before you blow-dry. We recommend that you look at the ingredients and look if it has silicon in it. Silicon is a great way to protect your hair from getting damaged by your hair dryer.


While the hair dryer does damage the hair in some ways it still depends on a lot of factors whether or not yours would be damaged. 

It depends on what hair type do you have, what temperature are you using it, how much do you use it and what products do you use in order to protect your hair from heat damage.

For the temperature, we recommend that you use the lowest setting so that the risk of you damaging your hair would be minimized.

Another thing that we strongly recommend is to use a heat protectant product that is silicon-based. And moisturize your hair as much as possible so that you won’t over-dry your hair while hair drying.

If you follow the proper precautions and your hair is still falling out, we recommend that you stop blow drying for a while and visit your doctor.
