What is a common effect of improper chemical application during a perm?

Increased hair moisture
Hair breakage or damage
Improved hair texture
Color fading

The correct answer is: Hair breakage or damage

Improper chemical application during a perm can lead to hair breakage or damage. This occurs because perms involve the use of strong chemicals that alter the structure of the hair. If these chemicals are not applied correctly—such as using incorrect processing times, inappropriate temperature, or an unsuitable perm solution—hair can become overly processed, resulting in weakened strands. This can lead to breakage, split ends, or even hair loss in severe cases. In contrast, options that mention increased moisture, improved texture, or color fading do not directly correlate with the consequence of a perm being improperly applied. While moisture levels can be negatively affected, the most notable and common issue resulting from improper application is the structural integrity of the hair, making breakage and damage the most significant risk.
