Why Use Low-pH Shampoos?
Let’s take a quick trip back to our chemistry lessons before we go through the best low-pH shampoos.
What Is pH?
The pH determines the acidity and alkalinity of a solution measured on a scale of zero to 14. Levels zero to 6 are acidic, level 7 is neutral, and levels 8 to 14 are alkaline. The abbreviation stands for “potential of hydrogen.”
Our hair and skin have natural pH levels that have to be maintained to keep them in their healthiest condition. But there are tons of factors that easily alter their pH levels.
The hair could easily lean toward the alkaline side due to coloring, styling, shampoos with alkaline ingredients, and even the water you use to shower.
When this happens, your strands become more prone to frizz, dullness, and breakage.
Keep in mind that one of the keys to maintaining healthy hair is keeping a balanced pH.
What Is the Optimal pH for Your Hair and Scalp?
The hair and scalp’s natural pH level is between 4.5 and 5.5, which is low on the pH scale. That means the hair and scalp are naturally acidic.
When external factors alter our hair’s pH, it could move toward the alkaline side. Therefore, in this case, keeping our hair and scalp healthy would require using low pH / acidic / pH-balanced shampoos and products.
Why Use Low pH Shampoos?
A study showed that hair fibers are more prone to friction that can damage the cuticles when the hair’s pH level increases.
Researchers found that the benefits of using low pH or pH-balanced shampoos prevent frizz and hair breakage.
