I don't have your hair properties, but I do notice that in the humid WI weather, especially since I started using henna (I'm wondering if henna reduced my porosity), products tend to sit on my hair. I absolutely have to keep moisture to a minimum, and I have to use less styling product. I even have to change how I apply product in the summer. In the winter, I remove excess water from my hair before I put my styling products in. In the summer, I have to do the exact opposite -put styling products in and then use a towel to blot out excess water.
2C/3A, fine, normal porosity.
