Neutralizer reduces the swelling caused by the _____________ of the perm solution.

• A. Acidity
• B. Alkalinity
• C. Viscosity
• D. Color

Answer: (B)

Neutralizer reduces the swelling caused by the alkalinity of the perm solution. The perm solution is highly alkaline to soften and swell the hair so it can take on a new shape. The neutralizer stops the chemical action and brings the pH back toward neutral, which also helps re-form the bonds to set the curl. Acidity, viscosity, or color aren’t driving the swelling in this context; it’s the alkaline environment that causes it, and neutralizing that alkalinity controls the swelling.
