Black hair PH MUST always be ACIDIC that is below 5 that is why we get so much BREAKAGE ladies...think of DRAINO that is what a PH over 5 is to your hair!!!!
What Ph Level Should Shampoo Be For Black Hair?
What? A pH of 6 is still acidic. The pH of water--which is neutral (i.e. Neither acidic nor basic) is 7. Anything below 7 is acidic, and anything above 7 is basic.
