I don't know. People found the pH thing and brought it to masses of people who do not know how products are manufactured. The people then seemed like they knew SO MUCH, but really, that's how products are formulated (at least if you are a good formulator).

pH of 6 is not outside of the range for hair. Optimal pH for hair products is 4-6

ETA: What products?
