The five attachments are designed to cover a wide range of hair: fine or thick, straight, wavy or curly. What changes is the routine. Fine hair usually needs smaller sections and a gentler setting; thick or very curly hair takes a little longer and benefits from being rough-dried first. Very short hair may not wrap fully around the curling barrels, but the brushes still work well for volume and smoothing.

The pre-styling dryer takes hair from wet to damp. The two curling barrels create curls and waves in opposite directions for a symmetrical finish. The smoothing brush gives you a sleek, straight look, and the volumising round brush adds lift and that classic blowout bend at the ends.

Yes, that's how it's meant to be used. Start with the pre-styling dryer on towel-dried hair until it is damp rather than wet, then switch to a styling attachment. Styling soaking-wet hair takes much longer and curls are less likely to hold.

The handle pushes warm air through whichever attachment you've clicked on, and the attachment gives hair its shape as it dries. Your hair is shaped by moving air and the form of the attachment, not pressed between two hot plates.

For most everyday looks, it's designed to stand in for a dryer, a curling tool, a hot brush and a straightening brush. If you love a pin-straight, glass-like finish or very tight ringlets, you may still want a specialist tool for those occasions.

Three things make the biggest difference. Start with hair that is damp, not wet or fully dry. Work in small sections, roughly the width of the barrel. Then let each curl cool in shape for a few seconds before you release it, and wait until all curls are cool before brushing them out. A light styling product applied beforehand helps hair that tends to drop.

Yes. The brushes work like a normal brush with a dryer built in, so most people get on with them straight away. The curling barrels take a few tries to get a feel for. Give yourself two or three sessions and it becomes second nature.
