Review (5/5): Surprisingly good!
I am truly surprised this works as well as it does. I bought it on a whim after seeing it in a video and I LOVE it!! I have super course curly hair and I put it in to air dry it curly or when I blow it out straight. It DOES NOT leave that residue either when I straighten it like Biosilk and any other serum I've tried. Overall, great product!!
