What is the pH range of cold waves?

The pH range of cold waves typically falls between 9 and 9.6. Cold waves, which are a type of hair processing product used in perming, utilize alkaline solutions to break the disulfide bonds in the hair strands. The higher pH level is crucial because it opens the hair cuticle, allowing for the restructuring of hair into the desired curl pattern.

In contrast, pH levels below 7 indicate acidity, which is unsuitable for this type of chemical process. A pH in the range of 7 to 8.5 might be usable for some hair treatments but does not provide the necessary alkalinity required for effective hair modification like cold waves. Therefore, the pH range of cold waves is essential to ensure proper performance and effectiveness in achieving the permanent wave hairstyle.
