Do automatic curling irons damage hair?

Like any heated styling tool, they can cause damage with excessive use or high temperatures. The Dyson Airwrap causes the least damage due to its lower maximum temperature. For traditional auto-curlers, use a heat protectant spray and keep temperatures below 375°F for fine hair.

How long do automatic curls last?

Automatic curls typically last 6-12 hours without product. Using a light-hold hairspray immediately after curling extends longevity to 24+ hours. Curls from higher-heat tools like the Chi Spin N Curl tend to last longer than the Dyson Airwrap's softer, lower-heat curls.
