Think cashmere. Swap out traditional sudsing shampoos, whether sulfate-free or not, and replace them with gentle, non-sudsing cream cleansers. Think “skin care for your hair.” Shampoo weekly or bi-weekly. Once a month or quarterly, depending on the thickness or density of your hair, apply your favorite sulfate-free sudsing cleanser to dry hair as a treatment to remove natural buildup.
Follow up with your favorite conditioner. The difference between a rinse-out conditioner and a leave-in: a leave-in conditioner is never in place of a rinse-out conditioner, only in addition to it.
