Your head appears white after shaving because your scalp, previously protected by your hair, is now exposed to the elements for the first time. Here's a breakdown:
Normally, people notice a white scalp after their first head shave. This is because:
- UV Protection: Before shaving, your hair acts as a natural barrier, shielding your scalp from direct sunlight and UV radiation.
- This protection means your scalp doesn't develop the same level of pigmentation (tanning) as other exposed areas of your skin.
- Reduced Pigmentation: Because it's been sheltered, the skin on your scalp is usually lighter than the skin on your face or neck.
- Shaving removes this protective hair, immediately revealing the lighter skin underneath.
- Temporary Effect: The whiteness is often temporary. With continued exposure to sunlight, your scalp will gradually tan and become less pale.
In essence, the white appearance is the result of your scalp's lighter, previously unexposed skin being suddenly visible after shaving.
