Ammonia-free perm solutions are associated with what odor characteristic?

• A. Very little odor
• B. Strong ammonia odor
• C. Unpleasant chemical odor
• D. No odor at all times

Answer: (A)

Ammonia-free perm solutions are designed to minimize odor by removing ammonia, the ingredient that causes the strong, sharp smell found in traditional perms. Without ammonia, the scent is much milder, so you typically notice very little odor during use. Some faint scent may come from other ingredients or added fragrance, but the pronounced ammonia odor is not present. This is why the best answer describes having very little odor.
