Calling out anybody*ladies*?

Since you said that you have thin hair, anything below 360 degrees is safe for your hair texture, so 260 degrees is okay. Anything above 360 is too much for fine, bleached, or damaged hair. Keep it on the lowest setting at all times when you're using it, as well as use a really good heat protectant. Overall, this straightener doesn't sound right for your hair, especially for everyday use. Use it sparingly!
