Which wave type is linked to inconsistent curl formation?

• A. Acid waves
• B. Alkaline waves
• C. Neutral waves
• D. Partial perms

Answer: (A)

Acid waves are the mildest perm option, using a lower pH and a gentler reducing agent. Because they work more slowly and rely more on the hair’s porosity and moisture to form the curl, differences along the hair strand—like varying porosity or moisture content—cause sections to soften and set at different rates. That uneven processing leads to some areas curling more or less than others, producing an inconsistent curl pattern. Alkaline waves, being stronger and causing more swelling, tend to yield more uniform results, while neutral waves sit between in strength. A partial perm is a technique choice, not a wave type.
