This product is for me a pure scam, given its price. Unless I misused ... I watched the video yet, and I already had the experience of the Brazilian smoothing, on me. There I made my daughter very long hair, thick and curly. After applying the product, the hair is sticky at will, and after smoothing they cling to each other, they get tangled automatically. A real horror.
After all stages of the Brazilian smoothing: the hair is just ... like before. But my wallet is relieved + 4h job!
