Which perm is also referred to as a hot perm, ionic perm, soft wave, or digital perm?

• A. Cold perm
• B. Heat
• C. Digital perm
• D. Alkaline perm

Answer: (B)

The key idea is whether heat is used during the perming process. Perms that require applying heat are known as hot or thermal perms. The terms hot perm, ionic perm, soft wave, and digital perm describe this heat-based approach from different angles, with digital perm being a modern technique within that same family. So the broad category that fits all those terms is the heat-based perm. Cold perms don’t use heat, so they don’t fit. Alkaline perm describes the chemical makeup rather than whether heat is involved, so it isn’t the right umbrella term.
