The term "pH" refers to the balance between acid and alkaline, which must be measured with the presence of water,because dry substances do not have a pH. pH ranges from 0 to 14, with 7.0 being neutral, like water anything under 7.0 is acid , anything above is alkaline. Human hair seems to like a mildly acid pH level. Although hair has no pH , the scalp and the natural oils which coat the cuticle of the hair do have a pHbetween 4.5 and 5.5. Shampoos that claim to be pH balanced usually range from 4.5 to 6.5. Basically , pH balanced means that the shampoo is gentle not harsh .
