How to Use a Diffuser – A Beginner’s Guide

If you’re looking for ways to improve your indoor air quality and create a more relaxing environment, using a diffuser is a great option. Diffusers are small devices that disperse essential oils into the air, providing numerous benefits such as improving respiratory function, reducing stress, and promoting better sleep.

In this article, we’ll go over everything you need to know about how to use a diffuser and more.

What is a hair diffuser?

A hair diffuser is an attachment for a blow dryer that helps to evenly disperse the air over a larger area of your hair. It is round and covered with “spikes” that help to keep your curls separated while creating more lift at the root.

Hair diffusers are especially beneficial for people with curly or wavy hair, as they can help to prevent frizz and define curls. They can also be used to add volume to straight hair and to dry hair more quickly and evenly.

To use a hair diffuser, simply attach it to the nozzle of your blow dryer and turn on the dryer on a low setting. Place the diffuser over a section of hair and move it in a circular motion. Be sure to keep the diffuser close to your scalp at the roots and then move it further away from your scalp as you dry the ends of your hair.

Benefits of using hair diffuser

Enhances Natural Curl Definition

The diffuser helps preserve and enhance the natural curl pattern of your hair. It disperses air evenly, reducing frizz and preventing the disruption of curls.

Reduces Frizz

By diffusing the airflow, you reduce the intensity of heat and airflow on your hair, which can help minimize frizz, flyaways, and static.

Gentle Drying

Traditional hair dryers can be harsh on curly hair, causing it to become dry and lose its natural bounce. A diffuser distributes heat more evenly and gently, preventing excessive drying and damage.

Prevents Heat Damage

Heat damage is a common concern when using high-temperature settings on hairdryers. A diffuser helps maintain a lower, more manageable heat level, reducing the risk of heat-related damage.

Adds Volume

The diffuser can also add volume to your hair, particularly at the roots. By lifting the hair and dispersing air around it, it creates a fuller look.

Speeds Up Drying Time

While a diffuser doesn’t work as quickly as a concentrated nozzle attachment, it can still speed up the drying process compared to air drying, making it a more convenient option for those with curly hair.

How to use diffuser: 3 different types of hair

Curly Hair

  • Start by washing and conditioning your hair with products suitable for your curl type. Apply a leave-in conditioner or curl-enhancing product if desired.
  • After washing, gently squeeze excess water from your hair with a microfiber towel. Avoid rubbing, as this can cause frizz.
  • Apply a curl-defining or anti-frizz styling product evenly through your hair, ensuring it’s distributed from roots to ends.
  • Attach the diffuser nozzle to your hair dryer. It’s important to use a diffuser designed for your specific hair dryer model.
  • Set your hair dryer to the lowest heat and lowest airflow settings to avoid damaging your hair and causing frizz.
  • Gather a section of your hair in the diffuser bowl, cupping your curls into the diffuser. Lift the diffuser towards your scalp without disturbing the curls too much.
  • Turn on the hair dryer and start diffusing, moving the diffuser in a circular or scrunching motion. Keep the diffuser moving to evenly distribute heat.
  • Work in sections until your hair is about 80-90% dry. Avoid touching your hair too much to prevent frizz.
  • Finish with a cool shot of air to set your curls.

Wavy Hair

  • Follow the same steps as for curly hair regarding washing, conditioning, and applying styling products suitable for wavy hair.
  • Gently towel dry your hair, removing excess moisture.
  • Attach the diffuser to your hair dryer, making sure it’s suitable for your hair dryer model.
  • Set your hair dryer to a medium heat and medium airflow setting.
  • Start diffusing your hair by cupping sections into the diffuser and scrunching upwards. This helps create volume and enhance your waves.
  • Continue diffusing your hair section by section until it’s mostly dry. Avoid over-drying to prevent frizz.
  • Finish with a cool shot of air to set your waves and reduce any residual frizz.

Straight Hair (Adding Volume)

  • Start with clean, towel-dried hair. Apply a volumizing mousse or spray to your roots for added lift.
  • Attach the diffuser to your hair dryer, ensuring it’s compatible with your hair dryer model.
  • Set your hair dryer to the lowest heat and highest airflow settings.
  • Flip your head upside down to maximize volume.
  • Use the diffuser to scrunch and lift your hair at the roots while blow-drying. Continue until your hair is completely dry.
  • Finish with a cool shot of air to set the volume.


  1. Are diffusers suitable for all hair types? Hair diffusers are most effective for curly, wavy, or textured hair types. They may not provide significant benefits for very straight hair.
  2. Do I need a special hair dryer for a diffuser attachment? Some diffusers are designed to fit specific hair dryer models, while others have universal attachments. Check the compatibility of your diffuser with your hair dryer or purchase a diffuser specifically designed for your dryer model.
  3. What products should I use with a diffuser? Use products that enhance your hair’s natural texture, such as curl-defining creams, mousse, or leave-in conditioners. Apply these products to damp hair before diffusing.
  4. Can I use a hair diffuser daily? Using a diffuser daily can be safe as long as you use it correctly and avoid excessive heat. Be mindful of not overdrying your hair, as frequent heat styling can lead to damage.
  5. How do I clean a hair diffuser attachment? Most diffuser attachments can be removed and cleaned by wiping them with a damp cloth or rinsing them under running water. Make sure to let them dry thoroughly before using them again
