Here is a list of the pros and cons of blow drying and important details to understand.


The pros of blow drying are all thanks to one thing: the temperature-adjusted drying function. It benefits users in the following ways:

a. Reduces Drying Time

The biggest advantage and primary function of a blow dryer is drying wet hair. This is a great way for those in a hurry to not leave the house with dripping strands. Hair that stays wet for too long can also result in breakage and attract bacteria. Drying hair quickly is definitely a win!

b. Prevents Wet Hair Overnight

Sleeping on wet hair is a big no-no for a lot of reasons. Tossing and turning on pillows while your hair is wet will lead to broken strands and even a fungal infection on your scalp. If you’re used to washing your hair before bed, a quick blow dry session can be of great help.

c. Simplifies Hair Styling

Blow drying is such a popular hair styling method because it gives you more control over the appearance and texture of your hair. Moreover, blow drying is the first step in most styling routines. It does the job of making your hair more manageable for more complex styles and drying it out thoroughly so other products can be applied with no issues.

d. Upgrades Your Appearance

Blow dried hair is also much more manageable than strands that are simply dried in the air. This is because heat styling tames the hair and reduces frizz. It can also add volume. A quick blow dry can make hair look well-groomed, which is sure to give anyone’s confidence a little boost.

e. Provides Long-Lasting Results

Any hair styling master will attest to the fact that blow drying provides the most long-lasting results in comparison to other hairstyling methods. The volume added through blow drying will maintain its shape for longer than other techniques.

But that’s not all!

Blow drying will also prevent issues such as flyaways, frizziness, excess moisture buildup, tangling, and more. Your hair won’t fall flat, and you’ll be able to enjoy the little pick-me-up of a fresh style for much longer.


Keep in mind that the effects of blow drying will affect your hair whether you use it for styling or simply rushing through drying out the strands.

a. Moisture Loss

Blow drying is typically done on semi-wet hair, and the purpose is to dry the excess water. If you continue to use the blow dryer for significantly longer, you strip moisture from the hair stands. Without moisture, your hair becomes too dry and prone to infections and dandruff. There are short-term solutions for this, but in the long run, you’ll experience weakening of strands, hair loss, and thinning.

b. Dullness

While blow drying can give your hair a nice and glossy look in an instant, regularly exposing the strands to high heat can cause them to lose their natural shine. And with long-term damage, getting your hair to look shiny and healthy will become a challenge even with blow drying and a lot of products.

c. Hair and Scalp Damage

Research has shown that blow drying one spot for too long or at too-high temperatures can severely damage the hair and scalp. If the heat is applied to sensitive areas, high-temperature drying can result in burns. This can lead to various hair and scalp issues, such as irritation, split ends, roughness, loss of color, etc.

d. Weakened Hair Follicles

The hair follicles on your scalp are where your new strands grow out from. As you may have guessed, hair follicles are quite sensitive to heat. Too much blow drying at high temperatures will cause severe damage to them. And unfortunately, damaged follicles are often the precursor to hair loss and thinning.

Note that this type of damage can also occur if you hold the blow dryer too close to the hair or scalp.

e. Only Suitable for Certain Hair Types

Improper blow drying will negatively affect all hair types, but the damage will be more severe for those with thin and fine strands. And blow drying hair that’s already weak or damaged is certainly a bad decision.

Due to the lack of strength, fine or thin hair will become brittle very quickly if regularly blow dried. Brittle hair is more prone to breakage, and it looks unnatural and often unsightly.

f. Texture Damage

Over time, blow drying your hair can cause its natural texture to change, and not in a good way. Texture damage will often result in an increase in frizziness, dryness, and roughness. And this happens most often to hair that’s blow dried at very high temperatures.

Tips for Blow Drying Hair

You now have a better idea about what can happen to your hair when you blow dry it, both the benefits and the drawbacks. And while the disadvantages may be scary enough to prevent you from doing it again, there’s no need to feel defeated!

We’ve got some valuable tips, tricks, and best practices that will help you gain all the pros and avoid the cons whenever you blow dry your hair. Following the right steps can ensure that your hair remains healthy and you’ll get better results and the looks you’re trying to achieve.

1. Wash Your Hair First

Clean hair is easier to style compared to oily or dirty hair. However, you don’t want to make the strands more vulnerable to damage by stripping all the natural oils from it. A simple solution is switching out your bottle of regular shampoo for a more moisturizing one. Make sure to use one that suits your hair type.

2. Towel Dry

Towel-drying wet hair removes excess water from the strands, which can make it vulnerable to heat damage. You can gently rub your hair with a towel or simply leave your hair in a towel wrap for a couple of minutes before you begin blow drying.

3. Use a Good Blow Dryer

Look for a hair dryer with multiple heat and air settings and features. This will give you enough control to minimize hair damage.

4. Use Medium or Low Heat

Stay in the medium and low temperature range when blow drying your semi-wet hair. The purpose of the heat is to gently dry the strands and change their shape just a little.

5. Section Your Hair

Detangle your hair and separate and clip it into small sections of similar thickness and length. This helps speed up the process and provides better results, reducing the time your hair has to be under the heat.

Use gentle strokes when detangling your hair. Do not pull it too harshly downward.

6. Avoid Blow Drying Your Hair Too Often

Don’t blow dry your hair every day. Space sessions out by a few days to minimize heat damage. You can alternate between air, towel, and other hair drying and styling methods. Just make sure you’re not using heat too often.

7. Do Not Blow Dry One Spot for Too Long

Blow drying one spot for more than a few seconds can burn your hair or even your scalp. To avoid this, work on small areas at a time. Always hold the dryer at a 15-centimeter or 5-inch distance from the scalp.

8. Use Heat Protection Products

Applying heat protection products on your hair before blow drying can also minimize heat-related damage. You can go for a hair protectant spray or use home remedies like unrefined coconut oil.

9. Finish the Blow Dry with Cool Air

When you think your hair is almost completely dry, switch to a cool air setting. This should help lock in some of the shine.
