What is the pH range of acid waves?

The correct pH range for acid waves is typically around 5.0 to 6.5. Acid waves are designed to work at a lower pH, which helps to close the cuticle and minimize damage to the hair. This lower pH level allows for a gentler perming process, producing softer, more natural-looking waves. Acid waves are ideal for color-treated or damaged hair because they are less aggressive compared to alkaline waves.

Understanding the pH scale is essential in the context of hair chemistry, as different pH levels can significantly affect the hair structure. Acidic pH ranges also assist in providing better curl retention and overall hair health post-treatment.
