What is the pH level of hair, skin, and nails?

2.5-3.5
4.5-5.5
6.5-7.5
8.5-9.5

The correct answer is: 2.5-3.5

The pH level of hair, skin, and nails is typically between 2.5-3.5. This level falls within the range of 0 to 14, with a pH of 7 being neutral. Options B, C, and D are incorrect because they fall outside of the normal pH range for hair, skin, and nails. If the pH level of these body parts was too high (as in options C and D), it could lead to issues such as dryness and breakage. Option B is also outside of the normal pH range and could potentially cause irritation and other problems. Option A is the correct answer as it falls within the appropriate range and helps maintain the overall health and strength of hair, skin, and nails.
