Question -   Does the pH of a shampoo change when it is heated or cooled?
------------------------------------------------------
The pH probably does not change much over the range of temperature that you would use it. 
Personal care products like shampoo are "buffered" so that the addition of acid or base 
does not cause the pH to change.
