If you flat iron your hair at a shallow temperature, it can deduct the shine from your hair and make it look more damaged. But if you heat your flat iron to the maximum temperature, it dries your hair and may also have the risk of burning them. The temperature that can burn your hair is anything over 420 degrees Fahrenheit. At the highest point, the keratin protein present in your hair will reduce, and there is no chance of deep conditioning that can help. According to the research analyst, 365 degrees Fahrenheit is the right temperature, which lets you give the perfect straight look. Not only that, but it also retains moisture and nourishes your hair. And you get that shiny, glossy, and smooth finish of straight hair at home. Keeping the right temperature of heat while ironing is essential.
