The statement regarding normal hair growth that is considered true is that shaving or cutting does not impact growth. Many people believe that shaving hair makes it grow back thicker or faster; however, this is a myth. Hair growth is determined by factors such as genetics, health, and hormonal levels, rather than the act of cutting or shaving hair. When hair is cut, it simply appears thicker because the ends are blunt, but this does not influence the rate at which the hair grows from the follicle.

Other options suggest that certain practices can enhance or speed up hair growth, which is not supported by scientific evidence. Applying conditioner, for example, may improve the hair's moisture and appearance but does not influence the growth rate. Similarly, frequent washing can help maintain cleanliness and overall scalp health, but it does not accelerate the natural growth process. The use of heat tools can affect the hair's condition by causing potential damage, but it does not enhance the speed at which hair grows.
