How Does a Hair Diffuser Work?

Purpose

A hair diffuser is an attachment you place at the end of your blow dryer. Unlike a concentrator attachment, a diffuser is meant to add natural volume to hair. There are even techniques you can use to maximize volume potential from a diffuser. A hair diffuser is popular during the summer, says homemakers.com, because it leaves your hair with a natural look as opposed to using a curling iron.
According to homemakers.com, diffusers work by preventing air from your blow dryer from penetrating your hair. Instead, the actual heat dries and adds volume to hair. It's a low-maintenance tool and is safer than flat irons, curling irons, concentrator attachments and blow dryers. Also, the lack of air blowing helps to prevent frizz.

Usage

Although hair diffusers add volume to hair, they're essentially designed for all hair types, according to homemakers.com. Use a hair diffuser to give body to straight hair and to maximize curls in wavy hair. Short-hair and long-hair types can benefit from this type of blow dryer attachment.
Place the hair diffuser directly to your roots when drying your hair. Move the hair dryer in a circular motion to promote volume at your scalp. Hdryers.com recommends that you use the lowest speed on your blow dryer in order to prevent damage to your hair. Once your roots are dry, continue moving the diffuser slowly down the length of your hair in the same circular motion until you reach your ends. According to hdryers.com, the diffuser is most effective when you hold the blow dryer at a 90-degree angle to your roots. For maximum volume, do the same process with your head flipped over.

Considerations

Hair diffusers are often sold with hair dryers. However, if you don't have one, the attachments are sold separately at beauty stores. Make sure your hair dryer is compatible with the diffuser attachment by looking for the model on the package.
Before using the diffuser, homemakers.com recommends that you apply a hair product to maximize volume and control frizz. Try a curling cream if you have natural wave or curls. If your hair is particularly prone to frizz, use an anti-frizz serum. Apply either product sparingly in order to avoid weighing down your hair. Follow with hair spray to help keep your hairstyle in place.
