After about a month I can say that the agent really works. Until now, the promised action is no exaggeration and no marketing lie. We'll see if it stays that way. Other agents had not helped so far. I have tried various conditioners, in principle, without improvement. It is now already really surprised when a product does what it says.
Update: It keeps at least 6 months.. No bubbling! Excellent! Update after 1 year: A new application after 10 months and everything blubberfrei again. Update after 2 years: still super, when applied regularly. As before: many tried, no comparison!
