Which of the following is NOT a component of all acid waves?

• A. Silicone conditioner
• B. Activator
• C. Wavy lotion
• D. Neutralizer

Answer: (A)

Acid waves rely on two chemical steps to reshape the hair: a waving solution that reduces disulfide bonds so the hair can straighten or wrap into a new curl, and a neutralizer that re-forms those bonds in the new pattern. Many systems also include an activator to help the waving solution work more effectively. A silicone conditioner, while useful for conditioning and adding shine after the process, isn’t a required chemical component of every acid wave system. It’s a post-treatment product rather than part of the core chemical steps, so it isn’t universally present in all acid waves.
