Question: 1 / 400

What range does the pH of shampoo fall in?

2.5-4.5 pH

Shampoo typically falls within the pH range of 2.5-4.5. This pH range is slightly acidic, which helps in keeping the hair cuticle closed and maintaining the natural pH balance of the scalp. Shampoos with a pH higher than 4.5 can lead to the hair cuticle being lifted, causing frizz and damage. Options B, C, and D have pH ranges that are higher than the typical range for shampoo and would not be as effective or beneficial for hair care.
