How does shaving affect hair growth?

  1. Removes hair permanently

  2. Has no effect on hair growth

  3. Leaves hair roots intact and grows back in 24-48 hours

  4. Reduces hair thickness over time

The correct answer is: Leaves hair roots intact and grows back in 24-48 hours

Shaving affects hair growth in a way that leaves the hair roots intact, which means that the actual hair follicle remains unchanged beneath the skin. When hair is shaved, it is cut at the surface of the skin, and because of this, the hair will grow back relatively quickly, typically within 24-48 hours. This rapid regrowth can give the impression that shaving increases hair thickness, but in reality, the hair is just growing back from the point at which it was cut. Shaving does not alter the hair's structure or its growth cycle, as it does not remove the hair from the root. Permanent hair removal methods involve destroying the hair follicle itself, which shaving does not do. Additionally, while some hair removal techniques, like waxing or laser treatments, can lead to finer hair over time, shaving does not have the same corrective effect on hair thickness. Therefore, choosing this option accurately describes the immediate and natural outcome of shaving hair.
