Which of the following is NOT a common hair treatment?

• A. Deep conditioning
• B. Color treatment
• C. Particle board treatment
• D. Hair straightening

Answer: (C)

The correct choice identifies "Particle board treatment" as not being a common hair treatment. In the cosmetology field, hair treatments typically focus on enhancing or altering the hair's appearance and health. Options like deep conditioning, color treatment, and hair straightening are all widely recognized services. Deep conditioning is used to restore moisture and repair damage, color treatment refers to the application of dye or highlights to change hair color, and hair straightening involves techniques to alter the hair's texture for a smoother appearance. On the other hand, "particle board treatment" does not pertain to hair care and is associated with materials used in furniture or construction, rather than cosmetology. This distinction makes it clear why that option stands out as irrelevant to hair treatments.
