If the hair is natural and healthy by nature, then for its straightening it is not necessary to use additional precautions using the iron. But in the case when the hair does not differ in density and natural brilliance, the device should be used no more than a couple of times a week. In addition, in order to avoid overdrying the strands and as a result of their brittleness, it is better to apply a special thermal protection tool to the curls before the start of the straightening procedure.
