Amway Satinique Glossy Repair Shampoo 250Ml

I have serious doubts about this shampoo. I use the brand for many years (buying it directly with Amway) and it has work perfectly. But after 3 days I started using the shampoo I bought at Amazon my hair started looking greasy, heavy, and I have to use a lot of shampoo to wash.Went back to my original shampoo bought at Amway and after the first wash my hair was shinny and clean again.
