The pH Balance of Hair:
The natural oil that our hair secretes is a natural oil called sebum. Sebum maintains the moisture and balance in our hair. The hairs natural pH balance is between 4.5 and 5.5 scale.
What is pH exactly?
It is a form of measuring a substance for levels of Alkaline or Acid. The scale is from 0 (strongly Acidic) to 14 (Strongly Alkaline) with 7 representing neutrality. So when most products say they are pH balanced they are usually a value of 7 or 8 on the pH scale. These levels represent the majority of shampoos available on the market.
Hair that is damaged is dry with a pH balance that is not between the 4.5 and 5.5 scale. If we use products with a high pH balance this is when we start to loose the necessary moisture in healthy hair.
Most store bought products have a pH balance that is well above our natural level maximum of 5.5. Most shampoos have a pH balance of about 7 or 8 on the pH scale. This is much too high and dries out the hair. Levels as high as 7 or 8 on the pH scale is too close to alkalinity – drying the hair out because the alkaline strips the hair of sebum a natural oil necessary for healthy hair.
Do relaxers, straighteners, perms or colors harm the natural pH balance of my hair?
Chemicals that are applied to the hair can alter the pH balance of the hair. Chemicals such as permanent hair colors, relaxers, straighteners and perms are all extremely high on the pH scale.
