Which statement best describes ammonia-free perm solutions?

• A. Very little odor
• B. They always cause less damage
• C. They do not require neutralizer
• D. They are always permanent

Answer: (A)

Ammonia-free perm solutions are designed to minimize the strong smell caused by ammonia. By removing ammonia and using alternative alkalizing ingredients, these formulas reduce odor while still allowing the chemical process to rearrange the hair’s bonds. The most noticeable and defining feature is the much lower odor, making the service more comfortable. This doesn’t automatically mean less damage in every case, nor does it negate the need for a neutralizer to rebuild bonds after processing, and they are still considered permanent waves. So the best description is that they have very little odor.
