Nizoral Shampoo for Hair Loss | DERMAdoctor Our Most Popular Brands Doctors have known for a long time that Nizoral shampoo, in prescription and non-prescription strength, works well for controlling dandruff. But at last year's meeting of the American Academy of Dermatology, a group of scientists suggested that over-the-counter Nizoral might also be useful as a hair loss remedy.Still, it's not all flimflam. The study met the basic standards of good research: It was a randomized, double-blinded study. That means the researchers used a random process to decide who would use Nizoral and who would use the zinc pyrithione shampoo. Also, the study participants didn't know which shampoo they were using, and neither did the researchers, until the results were in. Both of these measures are important in conducting a scientific study because they help eliminate any bias the researcher s or the study participants may have, which could skew the results.
