Shampoo is slightly acidic, If using universal indicator paper I would say light orange/yellow.
This is because the acidity helps make the cuticle smoother, making the small overlapping scales on the hair lie flat.
Shampoos are lighty acidic, with a pH between 6 and 7; with the Merck pH paper art. 9565 the color can be a shade of green.
if pH paper is dipped in a strong acid it turns red and if the same pH paper is dipped in the weak acid it turns blue
blue because it is a weak alkali
The litmus paper will turn red.
Red, it turns blue in base.
It would turn purple because it is used in the house. So it is a household item.
