Why Is Shampoo Foam Always White?

Question

Regardless of the hue of the shampoo, why does the lather remain white?

Answer 1

The color of a shampoo’s foam is always white since foam is created when air and water are mixed so the shampoo’s dyes get greatly diluted even further. The bumpy molecular architecture of the foam allows light waves to be redirected, and this makes it hard for the human eye to see any color still present.
