Hair pack for the rainy season

My hair tangles easily, and as I get older, it seems to have turned slightly curly.

My hair wasn't improving much with just rinse or treatment, so I thought about it and bought a hair pack. After using it, my hair felt like it had improved much more than with rinse or treatment, even though it might be temporary.

It seems like using it even during the rainy season makes hair a little less frizzy.
