Product Buildup on Curly Hair
Product buildup mimics the symptoms of dryness -- dull, flat, hard-to-manage curls -- which is exactly why it gets misdiagnosed so often. The fix isn't more moisture, it's a clarifying or chelating wash that actually removes what's coating the strand.

Product Buildup on Curly Hair: Signs and How to Clarify
Read itWhy buildup and dryness look identical
Both show up as dull, flat, hard-to-detangle curls that don't respond the way they used to -- which is exactly why buildup gets treated with more moisturizer so often. The difference is what's actually happening: dryness means the strand doesn't have enough moisture, while buildup means moisture can't get in at all because something (heavy oils, butters, or unrinsed styling product) is sitting on top of the hair blocking it. Adding more product to buildup makes the coating thicker, not better.
A realistic clarifying schedule
Most curl routines benefit from clarifying somewhere between every one and four weeks, depending on how much product is used and how hard the water is -- heavier routines with a lot of oils, butters, or gels need it more often than lighter ones. Clarifying isn't a harsh once-a-year strip-down; it's a routine reset, and a gentler chelating or sulfate-free clarifying wash used regularly does less damage than waiting until buildup is severe enough to need something stronger.
