Rainy season hair care items

I use Tony Moly Moisture Wave Lotion after shampooing. I initially bought it for hair volume, but as I continued using it, I found that on humid and hot days like these, when I sweat a lot and my hair gets frizzy and loses its curl from the iron, applying it immediately calms it down and brings back the volume I worked so hard to style. Also, if I apply it immediately while my hair is still wet after shampooing, it prevents frizz and adds shine, which I am very satisfied with. Since it is affordable when bought during a sale, it is great for using liberally.
