I use a cooling shampoo during the rainy season.

On rainy days, I found that using products with good moisturizing properties actually makes my hair greasy quickly, so I end up shampooing frequently. That's why I've been using a menthol shampoo I bought from Dandruff. Because it contains menthol and carbonated water, the cooling sensation when using it is incredible. It's a shampoo that makes my scalp feel cool and refreshed. Plus, since it even controls excess sebum, it's a shampoo I enjoy using during the summer.
