Shaving removes hair by cutting the hair shaft at the skin's surface.
The Mechanism of Shaving
Essentially, a razor acts as a cutting tool that removes the visible part of the hair. Here's a closer look:
- Cutting the Hair Shaft: As the razor blade moves across the skin, it slices through the hair shaft, effectively removing the portion that has emerged from the follicle. This is precisely what happens according to the provided reference: "A razor removes the tip of the hair shaft that has grown out through the skin".
- Surface Removal: Shaving only deals with the visible part of the hair. It does not remove the hair follicle beneath the skin's surface. This is why hair grows back after shaving.
Types of Razors
Razors come in various forms, as noted in the reference:
- Disposable Razors: These are designed for single or short-term use and are discarded after.
- Razors with Disposable Blades: These razors have a reusable handle and interchangeable blades. This allows for blade replacement, ensuring sharpness.
- Electric Razors: Electric razors use oscillating or rotating blades protected by a guard. They cut the hair close to the skin without direct blade contact.
Common Shaving Areas
The reference also notes where people typically shave:
- Men: Commonly shave their faces.
- Women: Frequently shave their underarms, legs, and bikini areas.
How Often to Shave
The frequency of shaving depends on individual preferences and hair growth rate. Since shaving only cuts the surface hair, the hair will continue to grow. Some people shave daily, while others shave less often.
