How does a soft curl perm differ from a traditional perm?

• A. Traditional perms use defined curls with standard rod sizes; soft curl uses milder solutions and larger rods to create looser, more natural waves.
• B. Soft curl uses stronger solutions and smaller rods.
• C. Soft curl uses the same rod sizes as traditional perms.
• D. Soft curl uses heat only.

Answer: (A)

The way a curl forms in a perm depends on how strong the chemical is and how large the rods are. Traditional perms aim for defined, tight curls by using standard rod sizes and a relatively stronger reducing solution that breaks and reshapes the bonds quickly. In a soft curl perm, the approach changes: you use milder solutions and larger rods, which limits how tightly the hair can curl and yields looser, more natural-looking waves. After the hair is wrapped and processed, the neutralizer re-hardens the bonds in this gentler shape, locking in the softer texture. Heat isn’t the defining factor here; the key difference is the combination of a milder chemical and larger rod sizes to create looser waves.
