Ever wondered about the fun side of pH balance? Get your lab coats on and join us on this rollercoaster ride through the mysterious world of hair product pH levels!
The Formula
pH = -log[H+] Alas, our fun ride has to sober up as we deal with the nitty-gritty of pH calculations. This formula calculates the pH based on the hydrogen ion concentration ([H+]).
