The DevaFuser from Deva Concepts boasts a quirky shape and bright green color that make it look like it originated in a salon on Mars, but it's quite a practical product. The unique ergonomic design delivers air more effectively, and the universal adaptor promises to fit 99% of all hair dryers. You'll also get a free 3 oz. bottle of setting spray so you can lock in the style you love.

Another diffuser that offers great fit is the Solia Universal Diffuser. This Italian-made styling tool offers an adjustable collar to fit most hair dryers. It's also super versatile, with 2 detachable diffuser rings; one with fingers and one without; to create a wider variety of styles.

Are you a frequent traveler who wants gorgeous style while away from home, without the bulk and hassle of hair dryer attachments? The Hot Sock Diffuser can be the answer. This small light foam diffuser fits easily on any hair dryer to provide adequate protection from heat damage. While it doesn't offer all the features of a traditional hard diffuser, it's a quick and easy alternative that works fine in a pinch. It retails for around $5, so it can't hurt to have it on hand!
