What is the ideal pH level for hair products used in barbering?

The ideal pH level for hair products used in barbering is around 4.5 to 5.5. This pH range is considered optimal because it closely matches the natural pH of hair and scalp, which is typically slightly acidic. Maintaining a pH within this range helps to preserve the hair's integrity, moisture balance, and color while minimizing damage and irritation to the scalp.

Using products that are too alkaline, such as those with a pH above 7.0, can lead to cuticle lifting, making hair more prone to damage, frizz, and loss of moisture. Conversely, overly acidic products with pH levels around 3.0 to 4.0 can clarify the hair and scalp but may also strip essential oils and moisture if used excessively. Therefore, the 4.5 to 5.5 range strikes a balance that supports healthy hair and scalp conditions, making it ideal for barbering practices.
