Buyer Questions
What temperature should I use for a hair straightener?
Fine hair: 300–350°F; normal hair: 350–400°F; thick/coarse hair: 400–450°F. Always use a heat protectant spray first — high heat without protection causes significant cumulative damage.
Ceramic vs titanium flat iron — which is better?
Ceramic heats more evenly and is gentler on fine, damaged hair; titanium heats faster and holds temperature better for thick, coarse hair. Most professional irons use a ceramic-titanium blend.
How often can I straighten my hair without damage?
Daily straightening causes significant damage over time. Use a quality heat protectant, the lowest effective temperature, and deep condition weekly if straightening more than 3 times per week.
Is the Dyson Corrale worth $500?
For frequent users with fine to medium hair, yes — flexing plates reduce heat required by 30%, resulting in measurably less damage over months of daily use. Overkill for occasional straighteners.
