Unlike straightening or curling hair with a regular hair dryer, a diffuser allows your natural wavy or curly locks to maintain their shape while also adding more volume and shine. The attachment is essentially a large bell-shaped bowl with elongated prongs, which spread out and rotate to maximize the airflow hitting your strands. That multidirectional movement is what helps your waves and curls maintain their shape instead of clumping together and becoming frizzy.
To get the most out of your hair diffuser, you’ll want to make sure that it’s fit for your specific curl pattern. For example, if you have fine hair with looser curls or waves, look for a diffuser with a wider diameter so that it can accommodate your entire head of hair. If you have thicker, more dense hair with larger kinks and loops, a diffuser with more elongated prongs may be better suited for your hair.
Before using your hair diffuser, liberally spritz it with a heat protectant to create a barrier between the heat and your strands. You’ll also want to section your hair into manageable pieces to ensure that you can evenly dry each part of your strands. Then, start with the tips of your hair and work your way toward the roots, gently scrunching the ends as you go. If you have a cool shot setting on your hair dryer, use that to help set your curls and reduce frizz. And remember to keep a close eye on your time because over-drying your hair can lead to dullness and frizz. hair dryer diffuser
