That mostly depends on your hair texture, lifestyle and styling routine. If you’re someone who regularly uses a lot of styling products, you’ll want to use a clarifying shampoo once a week to cut through any buildup (which can weigh down your strands and dull them).
If you use styling products sparingly or have naturally drier hair, you’ll want to limit your use to once or twice a month, as a clarifying shampoo is so good at its job that it can be drying when used excessively. Regardless of how often you use a clarifying shampoo, always follow up with a conditioning treatment on the mid-lengths and ends of your hair to restore moisture.
