What is the lowest temperature that will style a wig? According to Wigs.com every heat-friendly synthetic wig has a temperature limit. If you are unsure of the limit for your particular wig, 260° Fahrenheit is a safe temperature. Beware of turning up the heat any higher than 270° F - 280° F because you could burn your wig.
