What pH value does Acid Wave typically fall under?

4.5-7.0
6.5-7.0
7.8-8.2
9.0-9.6

The correct answer is: 4.5-7.0

Acid waves, commonly known as acid perms, typically have a pH value that falls within the range of 5.0 to 5.6. This lower pH helps to create softer, more natural-looking curls while being gentler on the hair and less damaging compared to alkaline waves, which have a higher pH. Acid waves are suitable for more fragile or damaged hair because they create a curl with less swelling of the hair shaft. The formulation allows the perm solution to penetrate the hair cuticle effectively while minimizing harsh effects that can occur with higher pH solutions. Understanding the pH levels associated with different types of waves is crucial for hair professionals to select the most appropriate products for their clients' hair types and desired outcomes.
