It really depends on your hair type and goals, but if you asked us, we’d have to say definitely yes. While silicones can make your hair feel soft and silky after washing it, they only mask the underlying damage.  Plus, constantly having to use harsh surfactants and sulfates to wash out the ‘cones can cause damage to your hair over time. We’re personally a huge fan of co-washing, and silicones just aren’t compatible with it.
