Until very recently I associated pH levels only with facial skin and it blew my mind to know that pH levels played an important role in strength of our hair.
A pH scale of 0-6 is acidic, 7 is neutral and 8-14 is alkaline. Your ideal range is between 4.5-5.5. However what happened was that I was using store bought anti dandruff shampoo and the more I used it, it disrupted my pH balance. This resulted in breaking of hair due to poor hair strength and since my scalp was more alkaline, more of the oils got affected, resulting in dry scalp and dandruff. In short, using a product that maintains pH balance gives you the following benefits:
You could supplement the pH lotion with Petitgrain oil (extract from bitter orange) and Melissa oil to promote relaxation for your stressed scalp and to help with reducing appearance of skin imperfections.
