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 – have a pH balance of between 4.5 and 5.5. This natural hair acidity prevents fungi and bacteria in the hair and scalp, and keeps the cuticle closed and healthy.
The amount of hydrogen in a solution determines whether it is more acidic or alkaline. The higher the pH level the harsher the shampoo is on your hair.
The best pH level for shampoo is between 5 and 7.
