What temperature should thermal irons be for coarse hair?

What temperature should thermal irons be for coarse hair?

• A. Low to medium heat
• B. Higher heat setting with caution
• C. Medium heat with no caution
• D. No heat necessary

Answer: (B)

Coarse hair resists heat more than finer textures, so a higher temperature is needed to soften the bonds enough to straighten effectively. Pushing the iron to a higher setting lets you achieve a smooth result in fewer passes, which helps minimize overall heat exposure. But with more heat comes more risk of damage, so safety matters: test a small strand first, apply a heat-protectant product, and use a pressing cloth. Keep the iron moving and avoid leaving it on one spot to prevent scorching. If the hair is highly porous or chemically treated, adjust heat accordingly and monitor the result with the client’s goals and safety in mind.
