What is the primary difference between a cold wave and a regular perm?

1. Cold waves use alkaline solutions and require heat

2. Cold waves use alkaline solutions and do not require heat

3. Regular perms are performed on dry hair

4. Regular perms only use natural ingredients

The correct answer is: Cold waves use alkaline solutions and do not require heat

The primary difference between a cold wave and a regular perm lies in the type of solution used and the need for heat. Cold waves use alkaline solutions that work effectively at room temperature, allowing the hair to undergo the chemical process without the application of external heat. This method makes it more versatile and gentle on the hair while still providing long-lasting curls. In contrast, regular perms often involve the use of acid-based solutions that typically require heat to activate the curls. This heat helps to set the shape of the hair during the perming process. The misconception about heat is what distinguishes cold waves, enabling stylists to choose techniques based on the hair type and desired outcome.
