Does using shampoo and conditioner of different companies causes dandruff?

Dandruff is caused by a fungus called Malassezia, which naturally lives on the scalp and feeds on the scalp's natural oil. When Malassezia overgrows, it can cause dandruff. Using different brands of shampoo and conditioner does not directly cause dandruff. However, some shampoos and conditioners may be more effective than others in controlling Malassezia growth. Additionally, some people may have sensitivity or allergies to certain ingredients in shampoos and conditioners, which can cause dandruff. If you are experiencing dandruff, it is recommended to consult with a dermatologist to determine the underlying cause and receive appropriate treatment.
