I recommend Debon Charming Shampoo.

Debon Charming Shampoo is the shampoo I love using during the rainy season. It’s a shampoo full of memories, isn’t it? I think many of you will be familiar with it.

During the rainy season, using shampoos with excessive nutrients can easily make your hair oily. Charming Shampoo isn't greasy or irritating, so it's especially comfortable to use during the rainy season. The scent is nice, and above all, it's a great value shampoo, so I really like it.
