What is the recommended pH level for hairstyling products?

The recommended pH level for hairstyling products is between 4.5 and 5.5 because this range is generally close to the natural pH of human hair and scalp, which helps maintain the integrity and health of the hair. Products formulated within this pH range help to keep the cuticle layer of the hair smooth and can prevent damage or irritation. This pH balance ensures that the products are effective in styling while minimizing the risk of adverse reactions such as dryness or frizz, which can occur when using products that are too acidic or too alkaline. Maintaining a suitable pH level is crucial for effective hair care, as it supports the overall condition of the hair and scalp, promoting manageable and healthy-looking results.
