What is the purpose of a clarifying shampoo before color services in some cases?

• A. Deep condition the hair.
• B. Remove mineral buildup and product residues that hinder color uptake.
• C. Add color.
• D. Strip all pigment.

Answer: (B)

Clarifying shampoo before color services is used to remove mineral buildup and product residues that hinder color uptake. When hair accumulates minerals from water and from styling products, a film can form on the surface that acts as a barrier, preventing the dye from penetrating evenly. This can lead to uneven color, dull results, or unexpected shifts in shade. By thoroughly cleansing with a clarifier, you reset the hair’s surface so the color can saturate more uniformly and true to tone. It’s applied when buildup is present or when the surface is likely to resist color, and it’s not needed for every service because overuse can strip natural oils and affect how the hair holds color.
