Just a crazy idea, might well be I'm talking from deep within my rectum, but isn't hydrogen peroxide the (or onf of the) agent(s) used in hair bleaching products? Or was at least used in those some time back? from what I hear, nowadays bleachers are supposed to be more sensitive, but I don't really buy it, you need a structural pigment change and therefor you need agressive chemicals, so it might be a good idea to ask your hairstylist for bleach and try that?
Btw, Marcel, what brands for wood dyes do you know in Germany? Xyladecor only has a pretty limited color supply as it seems and I don't know if the color I want to achieve is within their spectrum. Thinking about it, maybe we should start a special thread for the continental European guys about brands, resources and stores/companies?
so long
