Potential of Hydrogen, or pH, is the measurement of how acidic or alkali a substance is. It is judged on a scale between 0 and 14. Anything between 0 and 6.9 is acidic, 7 is neutral, and anything between 7.1 and 14 is alkaline. Human hair and scalp oil, sebum, has a pH balance of between 4.5 and 5.5.
