I have tried using hair mousse on my wet hair and left it overnight to check whether I can get any curls, but to my dismay, I couldnât get my hair even a bit wavy. I even tried braiding my hair, but it didnât do any good either! Can somebody please tell me if there are any hair products that can curl my hair naturally? I have thin straight hair, and I am tired of using different techniques to curl them. I would be really thankful to you guys if you can help me with some great hair products to curl my hair without using heat on them! Please help!
