An ideal shampoo should possess the following properties:
1. Moderate cleansing ability, capable of removing deposits and scalp debris from the hair without causing excessive degreasing that results in dryness or coarseness;
2. The ability to generate a rich, fine, and reasonably stable lather during the washing process;
3. Ease of use and easy rinsability;
4. A gentle formulation that is non-toxic and causes minimal irritation to the eyes and scalp, ensuring safe usage;
5. Good combability-both when wet and dry-and the ability to impart a lustrous shine to the hair;
6. Moderate deposition of various conditioning agents and additives, ensuring that long-term, repeated use does not lead to excessive buildup;
7. A pleasant fragrance inherent to the product itself, as well as during and after use.
