Frequently Asked Questions
How often should I use ITSRT?
You only need to use ITSRT every 3 to 4 days (about twice a week) for 8 weeks. On the days you don’t use ITSRT, you can use your regular shampoo and conditioner.
Can I continue to use ITSRT?
Always follow the label instructions. You may use ITSRT every 3 to 4 days (about twice a week) for 8 weeks, then as needed to control dandruff.
Is ITSRT safe to use on color-treated or keratin-treated hair?
Yes, ITSRT is safe to use on color-treated, chemically processed, and gray hair.
Is it okay to use a conditioner with ITSRT?
We recommend using a conditioner between uses of ITSRT. Some dandruff shampoos don’t smell very good; how does ITSRT smell? ITSRT has a clean, fresh scent and a pearlescent, soft look and feel.
Does ITSRT work on severe dandruff?
Clinical studies show that ITSRT is effective in controlling symptoms of mild, moderate, and even severe dandruff, such as flaking, dryness, and itching.
How fast does ITSRT work?
Always follow the label instructions and use ITSRT every 3 to 4 days (about twice a week) for 8 weeks. Published clinical study results show that ketoconazole, the active ingredient in ITSRT, starts working from the first use to relieve dandruff symptoms and control the fungus that causes dandruff.
