How to Use a Diffuser on Curly Hair

BY: Shannon Grilli |Jan 16, 2018

Any woman with naturally curly hair will likely tell you that their ringlets are both a blessing and a curse. For some, especially those prone to frizz, that curse can last decades, from a poofy-scalped adolescence all the way up until the day they finally discover the secret tool capable of taming an unruly mane: the diffuser.

Unfortunately, owning a hair diffuser and knowing how to use a diffuser are two entirely different things. And your hair diffusing technique might differ widely depending on the length of your hair, the strength of your curl, and what you're trying to achieve. To help simplify the process, we threw together this quick tutorial for using a hair diffuser, and also made some product recommendations if you're in the market for this life-saving styling tool.

How to Use a Diffuser

Note: these instructions work best if you have naturally curly hair and are looking to enhance your curls. If you have straight or wavy hair, you might start by following these instructions, and then tweak your technique to find what works best for you.

1. After showering, remove excess water from hair by gently scrunching it with a towel. Refrain from rubbing or fussing with hair too much since this will disrupt the natural curl and cause frizz.

2. Generally speaking, it's best to avoid separating the curls as much as possible; however, if you are prone to tangles, you can run a wide-toothed comb through wet hair before diffusing. Just be sure to only comb as much as is absolutely necessary.

3. Apply your favorite curl-defining or anti-frizz product to hair by scrunching it into hair (rather than running your fingers through the strands).

4. Place the diffuser onto the nozzle of the hair dryer and switch it on. A medium setting is best as hotter hair encourages frizz. Holding your head to one side, pick up a large section of hair and gently place the ends into the bowl of the diffuser. Drying the bottom of the hair first, and the roots last, helps to ensure you get good volume at the crown, since it prevents the weight of wet hair from pulling the curls down.

5. As the hair dries, move the diffuser up toward the top of your head until the fingers of the diffuser are touching your scalp. Release the hair once it's reached 80-90% dryness.

6. Switch to the other side of the head and repeat with another section of hair. Keep going, alternating sides until all the hair has been diffused. Avoid combing or running your fingers through your hair at all costs!

7. If you need more volume at the crown, you can section off the top layer of your hair before starting and secure it with a clip. Diffuse this section separately after the rest of the hair has dried.

8. If your dry hair feels "crunchy" afterward, try gently scrunching it or carefully using a wide-tooth comb to soften and separate the curls.

How Does a Hair Diffuser Work?

Just what is it about this funny-looking tool that makes it a curly girl's best friend? Simple: the shape of the diffuser and the holes in it help to control and diffuse the air being forced out of the dryer, similar to the way a shower head helps control and diffuse water being fed through pipes. This helps ensure that the curls can dry more naturally, instead of being broken apart by a blast of air.

5 Great Diffusers for Curly Hair

So with so many diffusers on the market, how do you choose the right one? Some hair dryers come with diffusers already, and some of these add-on diffusers work great. You'll want to test yours out, though, to make sure it adequately diffuses the air flow to a gentle whisper. If you feel like you're still getting blasted with air, swap out the freebie diffuser for a more professional one.

Below, we curated this list of diffusers that pass the test.
