Which is better for fine or thin hair?

The Supersonic r. Its slim barrel and lower weight make it easier to keep the airflow moving, which matters on fine hair that overheats quickly. The HD11's higher airflow is more than fine hair needs.

Which dries thick or long hair faster?

The HD11. Its 1,700 W motor and wide head move more air per pass, which shortens drying time on dense or long hair. The r trades some of that for precision.

Is the Supersonic r worth the extra over the HD11?

There is no extra right now. At $349.85 versus $350.00 as of November 5, 2026, the r costs about the same, so pick on weight and barrel shape, not price.

The HD11 has years of real-world use behind it and widely available replacement parts. The r is newer with a shorter track record, though both share Dyson's heat-control design.

Can I travel with either one?

No. Neither is dual voltage, and both are built for 120 V US outlets. You would need a voltage converter abroad.

Do both include the Flyaway attachment?

The HD11 lists the Flyaway among its five intelligent attachments. The r includes five attachments too, but the listing does not name them, so check the box contents before buying.
