Which type of hair dye has large molecules that adhere to the hair shaft and are easily removed with a single shampoo?
Correct answer: D. Temporary
- A. Permanent
- B. Semi-permanent
- C. Demi-permanent
- D. Temporary
Explanation
The correct answer is Temporary. Temporary hair dyes are designed to coat the surface of the hair with large pigment molecules, which do not penetrate the hair shaft. This characteristic makes them easy to wash out with just one shampoo. In contrast, permanent, semi-permanent, and demi-permanent dyes have smaller molecules that penetrate the hair more deeply, making them resistant to being washed out quickly.
