Which of the following statements is true regarding normal hair growth?

The statement that shaving or cutting the hair has no effect on hair growth is accurate because the act of cutting or shaving hair does not influence the hair follicles’ activity or the speed of hair growth. Hair growth occurs at the root, beneath the skin, where the hair follicle is located, and cutting or shaving hair only affects the visible portion above the skin. Therefore, no matter how often hair is cut or shaved, it does not alter the growth rate or overall health of the hair.

While hair growth can be influenced by various factors such as genetics, age, and health, the structural integrity of the hair remains unaffected by trimming. This understanding helps to clarify common misconceptions surrounding hair maintenance and growth, especially regarding practices that are often thought to stimulate growth, such as regular haircuts.
