Answers
Answer:
The fourth brand which has pH 6.8 is better for smoother hair.
Explanation:
- The acidity of a substance is measured by its pH level.
- Because of the physical nature of hair, shampoos are designed to be acidic. Hair dissolves at a pH of 12 because strongly alkaline solutions disrupt the disulfide chemical links in hair.
- That's why hair stylists recommend slightly acidic and near neutral shampoo for smoother hair.
Hence the brand having pH 6.8 is better for smoother hair.
