Caution: New formula no longer froths

I use "Head & Shoulders Classic Clean" for many years (daily) and was very pleased so far. So far, relatively little is always enough shampoo to lather your hair and the rest of your body well can. Since I have, however, begun a new bottle "Head & Shoulders Classic Clean" a few weeks ago, I succeed in hardly even with considerably more shampoo, even still produce foam. No matter how much shampoo, I use, hardly the shampoo is applied to the hair, the foam decomposes and the hair feels oily to somehow. First I thought of a manufacturing defect and bought a new bottle "Head & Shoulders Classic Clean". But the new bottle had the same disappointing features. As I discovered on the bottle the words "Improved Formula" and now I realize that the recipe was changed obviously aware. For me, this shampoo with this new formulation is no longer usable. Too bad, will probably have to find a new favorite shampoo me ...
