What is the pH range of typical hair and skin?

The correct pH range for typical hair and skin is 4.5 to 5.5. This slightly acidic range is important for maintaining the health of both hair and skin. The acidity helps to protect the skin barrier and the hair cuticles, which are critical for preventing moisture loss and damage.

When hair and skin are within this pH range, they are better able to fend off harmful bacteria and other pathogens. Additionally, products formulated to match this pH can effectively balance and maintain the scalp and hair's natural condition without causing irritation or stripping essential oils.

Understanding this pH range assists barbers in selecting and recommending appropriate products for hair care, ensuring that they promote the overall health and integrity of their clients' hair and skin.
