You can still see hair after shaving because the razor only cuts the hair at the skin's surface, leaving the rest of the hair shaft and the root beneath the skin. It doesn't remove the entire hair follicle.
Here's a more detailed explanation:
- How Shaving Works: When you shave, the blade glides across your skin, severing the hair shaft at the point where it exits the skin.
- Hair Follicles Remain: The hair follicle, the structure beneath the skin that produces the hair, is not affected by shaving.
- Hair Regrowth: Because the follicle is intact, the hair will continue to grow. What you are seeing after shaving is the very short hair that remains just below the surface and quickly regrows.
- Perception of Hair: Sometimes, what you're seeing isn't hair that has grown back, but rather the very short stubble left behind after shaving. This stubble can become more noticeable as the surrounding skin recovers from any irritation caused by shaving.
- Ingrown Hairs: Sometimes, the hair can curl back into the skin as it regrows, resulting in an ingrown hair. This can appear as a small bump and may look like hair still present even after shaving.
In Summary: Shaving only removes the visible portion of the hair. The hair follicle remains intact, allowing the hair to grow back. What you see after shaving is either very short stubble or newly regrown hair.
