Have you seen this study? Japanese Nizoral study
Very small sample, but very interesting. Any comments?
Studies are great, but often difficult to dissect from a scientific perspective. Reading about the final results is one thing, but one must always have critical thinking. What I mean by this is that you must think of the motivation behind a study, and if the researchers will benefit from it (for example, by selling more product). Also, the methods used and the sample size are very important. The list goes on and on. Because of this, most studies are fairly weak.
The study in question about Nizoral is almost worthless with only 6 people enrolled. It reads more like someone’s homework assignment. One can not draw statistical significance to the data shown and without it, there is nothing worth believing.
