Do guys really use a hairdryer to blow dry their hair? I've had that question asked of me on multiple occasions and the answer is a resounding Yes. Do most guys use a hairdryer? No. Most guys don't know why they would need one, nor are they comfortable using one. I hope that I can explain why a hair dryer is a great tool for your styling toolbox.
"I get out of the shower, towel dry my hair, and add some hair product to it. My hair is short enough and as long as I use the right product, my hair stays in place."
The biggest problem with the statement above is about "using the right product". Typically when guys use this statement, they're using the wrong product and probably too much of it! Using product to control your hair will only result in your hair falling to where it naturally wants to go. Your hair has typically been trained, through years of styling it, to fall in a certain way and the best way to get your hair to stop falling in that direction is to use a hair dryer.
As your hair is drying it is starting to set into place. By using a hair dryer, along with a brush, your setting your hair in place where you want it to go. When the hair is dry, regardless of which product you put in it, the hair will naturally want to fall back into the general shape of where you had blow dried it. This allows you to use less product to achieve the hold and shine that you desire. Using less product will make sure your hair product lasts longer and will save you money in the long run.
In addition, when using pomade or hair paste, the product functions best when the hair is dry. The products adhere more easily and evenly when there is no extra moisture. So using a hair dryer for a minute or two before styling can prevent that extra greasiness or uneven product application.
After the hair is dry, it should be shaped, generally, where it needs to be for the style you're trying to achieve. All you have to do is add your styling product of choice to your hair. For most cases, an extreme hold product isn't needed any more and you won't need to add a bunch of product. Depending on the thickness and length of your hair, usually a dime to nickle size amount will be enough.
