I have used it and find its ok.
The blue powder bleach can also be used for full head/scalp applications as long as you do NOT go above 20 vol peroxide strength.
I have not used the cream bleach in the tube, so cannot comment on this.
The Blondor bleaches are more expensive compared to other brands.
One thing which is really annoying is that the tub of blue bleach does not have a scoop inside, and you have to manually empty the powder out of the tub. I much prefer it when you can just take the whole lid off and scoop the powder out.
I think its designed this way for when your using the scales to weigh it.
