Your hair type, hair section, and plate size determine the temperature suitable for your hair. As the highest heat setting can go as high as 410F and the lowest, 170F in most conventional hair styling tools. If your hair is exposed to a temperature in a range of 347-419 even for a few minutes, it can be damaged instantly, causing burns. Hence, it is advisable to keep the heating as low as possible and then expand until you feel satisfied.
