Since clarifying your hair does such a good job of purging your strands of any and every trace of oil and gunk, it also means that they can strip away the natural oils that keep your hair shiny and your scalp well-moisturized. You shouldn't use a clarifying or detox shampoo more than once a month. Think of your monthly clarifying session as a true beauty treatment, i.e. don’t rush through it when you’re already running late for work. Start by focusing the shampoo at your roots where buildup tends to be worst and massage your scalp to activate the sebaceous glands. Channel your inner salon shampoo station and really work those suds in (a little bonus scalp massage is never a bad thing), progressively spreading the shampoo through the length of your hair as you go. Rinse, then follow up with your favorite MopTop conditioner.
Hope this helps and remember, a good hair day can change the world!
