im about 15 and starting to need to start shaving and i have been told to use a an electric razor as long as i can because once i start using a regular razor it grows in thicker. first of all is that true? second, i've heard electric razors are very rough on your skin. ( i will probably buy a fairly cheap one). I've heard them referred to as lawnmowers. will an electric razor have a major effect on my skin and will it be a lasting effect?
