Shampooing often enough can keep oils at bay, helping with dandruff symptoms. We would recommend to shampoo at least once a day due to the weather in Singapore. While you are at it, try to resist the urge to scratch your scalp. Find and eliminate anything extra from your personal care routine. This includes gels, sprays, and other products so that you don’t make your symptoms worse. After your situation has been properly managed, you can then start to bring them back slowly.
