The heat perm produces soft looking waves and curls, which are more defined when ______ and looser when ______.

• A. Dry; Wet
• B. Wet; Dry
• C. Dry; Dry
• D. Wet; Wet

Answer: (A)

Moisture level after a heat perm controls how tight or loose the curl looks. The chemical process creates a new pattern and the shape is locked in as the hair dries. When the hair is dry, there’s less weight from water, so the strands hold the defined wave or curl more clearly. If the hair is wet, the added water weight and temporary hydrogen bonding relax the pattern, giving softer, looser waves. That’s why the defined result comes with dry hair and the looser look comes with wet hair.
