I love this product. A little goes a long way. I sprayed it on my towel dried hair and then continued with styling as normal but once my hair was dry it was so smooth no frizz that lasted the whole day and even when I wake up the next day I feel like it's still working. My only complaint is that I wish it was sold in a bigger bottle. I will definitely be repurchasing.
This lotion add shiny and volume to my hair. I using them on wet hair before hair drying.
I bought this to strengthen my hair because my front is graying and even with coloring the texture is no longer like before. What surprised me was it strengthened my hair by softening it, which also made styling easier too. There’s no noticeable product buildup either so I don’t have to shampoo more frequently than before. Overall a very satisfied customer!
