Diffuser Do on a Hair Dryer

If you’ve ever opened your hair dryer and found a round, pokey attachment that looks like a mini-version of the infamous blow-dryer nozzle, you’re not alone in being baffled by its purpose. But rest assured, that small piece of plastic can be your new best friend if you have curly or wavy hair, helping you to define and shape your curl pattern without blowing them into a frizzy mess.

Essentially, the diffuser is an attachment that clicks onto your nozzle to redirect (or diffuse) the airflow from your hair dryer with diffuser. While it’s most commonly used on wavy and curly hair to help define natural curl patterns, it can also be useful for adding volume and texture to straight locks.

Curly hair has a tendency to dry out faster than other textures, making it more susceptible to damage from constant heat styling. But if you use the right products and know how to properly apply your diffuser, it can actually reduce the time your hair takes to dry and improve its overall condition.

What Does a Diffuser Do on a Hair Dryer?

A good hair diffuser will have a lightweight, ergonomic design that’s easy to hold and comfortable to use for prolonged periods of time, particularly since diffusing is often done at different angles. It will also have a high wattage to ensure strong, fast airflow. And if you’re looking for a little extra help, consider one with ion technology that adds negative ions to your hair to prevent frizz and give it a gorgeous sheen.

When it comes to diffusing, the key is to start at the tips and work your way up toward the roots, gently scrunching your hair as you go to keep it shapely and full. Also, never over-dry your hair — once it’s 80% dry, turn off the dryer and let it finish drying naturally to avoid heat damage.

To achieve the most impressive results, you should be using a curl-enhancing product before applying your diffuser. A mousse for curly hair, curl cream or even a leave-in conditioner can help your hair retain its shape as it dries, while also giving it added bounce and definition.

After you’ve applied your hair-enhancing product, begin diffusing your tresses by turning your head upside down and placing a section of your hair in the diffuser. Press the diffuser against your hair to hold it in place, then start moving it around your head in circular motions to evenly distribute the heat. It may take a while for your hair to completely dry, but it will be worth the wait! And when you’re done, don’t forget to apply a finishing spray to seal in your style and protect against any future frizz.
