I have work on comparative analysis of different shampoo, which prove its better anti- Dandruff activity, i refer in many papers only fungal isolates (Malassezia Yeasts) are used to showing anti - dandruff activity. But i have a problem for identification of this fungi...all researchers says that isolate from scalp of person suffering from Dandruff..so please says any other method to prove the anti - dandruff activity of Shampoo, which i perform in my lab.
