With its diffuser, the Dyson Supersonic is many hairdressers' go-to for drying curly hair, including Jonny Eagland, senior stylist at John Frieda Salons, whose advice would be to go for it if your budget allows. “The airflow is so gentle and it has three different heat and speed settings, but it’s also super lightweight, so it won’t stress your shoulders when holding for a fair amount of time,” he says. If hair health is a huge priority for you and your curls, this could be just the thing when combined with hair repair products (our K18 review is an ideal treatment for fragile curls).

I have medium to long hair and the 700W power is ok for me. Drying my hair doesn’t take much longer than with my older hair dryer. It’s really light, and much easier to move around my scalp than a conventional hair dryer. The prongs are also a generous length and can reach the scalp, while the surface of the diffuser is covered with a good amount of holes. It also features adjustable airflow, meaning you can adapt the amount of air that comes through the dryer to suit your styling needs and preference. OK, we’ve convinced you that your dryer needs a diffuser to bring out the best in your curl pattern. The next question concerns what you actually need to look for in an attachment to make sure it’s right for both your hair and your dryer. Cloud Nine is another hairdresser-founded brand that makes great, quality tools, including some of the best hair straighteners on the market. So if you like the look of The Airshot dryer (or you already own one) then you’ll be pleased to hear that the brand also offers a matching diffuser. I’ve been using the Bellissima Diffon diffuser for while now and it’s been a game changer. My curls are really defined and look great.

Definitely! We – and no doubt thousands of other curly-haired women – can speak from experience that using a diffuser is a failsafe way to dry perfectly-defined curls. Because the air is distributed more evenly, it dries the hair more gently and therefore helps to preserve your curl pattern. Is it better to air dry curls or use a diffuser? If you know that your hair tends to go frizzy when you air dry, or that it takes hours to dry naturally on its own, you'll most likely find that using a diffuser and a dryer on a low speed, low heat setting gets you much better results. Is it healthier to use a diffuser on hair? First thing to note about it is that it’s very light and compact. The Bellissima Diffon is an all-in-one diffuser and hair dryer, therefore there is no need to attach it to a hair dryer. It’s got an ergonomic design that makes it really easy to hold when drying your hair. This is so much better than holding a hairdryer and huge diffuser for ages, especially if you have a lot of hair.
