Bests & Worsts Reviews from Amazon

I am strongly recommended customer did not buy this product,especially for sensitive skin type.when I was using second steps,my eyes can't open and I can't stop to cough,I washed it all,using shampoo and mask to product my hair.I am not sure if I am using flat iron,I would prefer using seishido,so the smell is bad ,but it's acceptable when finish have better results
