Having read reviews that it was good as a mask, the first time I held him for 15 minutes, my hair bleached so glad that it grab as much !, I could not wash it off, as a result went 2 days with bun :)) Then just looking for the best time for your hair: air conditioning I did nanoshu and almost immediately wash off, the hair soft, light and do not get confused. And for the mask, I poured it into an old jar of mask, add a few drops of a toning balm Tonic (I Mother of Pearl), mix well and get a great mask for toning yellowness (Tonic dries hair, and the air conditioning supplies, as a result of an excellent mix), the Council only Tonic drip a little bit to slightly blue, and try, if you want more - add another ******* more reviews on products iHerb you will find on my page, just click on the highlighted blue nickname "0bovsemka". Pleasant and useful purchases!
