Splints can cause some damage to the hair. Splints generally require high temperatures generated by energizing the hair to make it straight or curly. The temperature at which the hair is styled is generally around 100 to 200 degrees Celsius, and the high temperature destroys the proteins in the hair, thus denaturing them. Therefore, the use of splints can cause some damage to the hair, which may result in split ends, breakage, hair loss, yellowing and other manifestations of the hair. Therefore, you should pay attention to the following points when using splints in general. Firstly, minimize the frequency of using splints, and try to use splints at temperatures below 150 degrees Celsius to prevent greater damage to the hair; secondly, comb the hair neatly before using splints, and avoid using splints when the hair is tangled; finally, avoid staying in one part for a long time when using splints. The use of splints can be damaging to the hair, so try to avoid using them.
