What is the ph of shampoo?

Shampoo typically has a pH value that ranges from 4 to 7. Variations in pH can be due to differences in formulation and intended use. Shampoos that are designed for normal hair typically have a pH value between 5 and 7, while those that are designed for oily or damaged hair might have a slightly lower or higher pH value. Generally, shampoos that have a lower pH value can be more acidic and may help to remove buildup and restore the natural balance of the scalp. However, shampoos that have a higher pH value can be more alkaline and may help to eliminate dandruff and improve overall hair texture. Ultimately, the choice of shampoo depends on individual hair type and specific haircare needs.
