A 4-week active rotation calendar
The "rotate your actives" advice is everywhere, but nobody publishes the actual calendar. Here it is: weeks one and two, ketoconazole shampoo twice weekly with a gentle regular shampoo for other washes. Weeks three and four, switch to zinc pyrithione twice weekly, same gentle shampoo between. If flakes persist into week five, rotate to selenium sulfide for weeks five and six. Throughout, keep one wash a week as a plain gentle shampoo with no active, giving the scalp a rest day. Judge each active at the two-week mark: reduced itch first, then fewer flakes. Do not rotate faster than this; weekly switching never lets any mechanism work. Log each rotation's start date on your phone; the calendar only works if you track it. If three rotations fail, the problem may not be dandruff at all, which is the dermatologist checkpoint. For the antifungal head-to-head, the ketoconazole versus zinc comparison breaks down the two main actives.
Tapering off without rebound flakes
Stopping a medicated shampoo cold is the classic rebound trigger. The taper protocol runs over six weeks: from twice weekly to once weekly for two weeks, then once every ten days for two weeks, then biweekly. At each step, watch for the pre-flake signal, which is itch returning before visible flakes; itch at a step means hold that frequency another two weeks before stepping down further. The maintenance landing zone for most people is biweekly or monthly, not zero; dandruff is a managed condition, and the scalp's fungal balance drifts back without maintenance. What does not work is tapering by diluting the shampoo or using less product; frequency is the variable, not dose. If itch returns at any step, hold that frequency for two more weeks before trying again. For the product comparison, the anti-dandruff top models page lines up the Nizoral and T-Gel options.
