good smelling, but slow-acting shampoo

As requirements I have to an anti-dandruff shampoo that quickly shed away and this prevents the longer term. For this, the hair should not be so quick greasing.
Whether the shampoo foams good or excellent odor I do not care - because the power has to be right with visible (who already smells on my hair?)

Previously I had the "L'Oréal Paris Elvive Anti-Dandruff Shampoo Intensive" and was more than satisfied, unfortunately this gradually disappeared from the retail and now Amazon :-(

So I gave the Nivea Shampoo again a chance, only to find the following:
- Visibly fewer shed after over 1 week Application
- Greater amount of shampoo or partially twice washed necessary (when I tried it with too little)
- Scalp itch easily, which leaves me with but after 10-15 minutes after
- In waiver of the shampoo and change to a non anti-dandruff shampoo are after 3-4 days back shed.
- Hair fat faster after than other (anti-dandruff) shampoo.

because the shampoo on the whole his ZWEK met three star. Compared to the "L'Oréal Paris Elvive" but significantly worse (but better smelling).
I will add a response again when the first bottle is empty and will until then now renounce the exchange with other shampoos.
