Are sulfate-free and silicone-free conditioners actually better for damaged hair?

The consensus from specialist hair-care communities is that it depends on the rest of your routine. Sulfate-free formulas are gentler on color-treated hair, and avoiding silicones can help low-porosity or curly hair feel less weighed down, but silicones themselves are not damaging to most hair types. Match the formula to your hair's porosity and your styling routine.
