Although the color in the hair keeps super, but unfortunately also on everything else. One should definitely wear gloves when coloring, to lubricate the ears and forehead with milking grease and wash immediately after staining everything. This stuff keeps on skin unfortunately insanely good and long. For clothing, however it is fine out again.
Another negative point is that it bleeds long (though without sacrificing on color strength, but it then turns everything it touches).
Rain is not a problem as long as there is no rain, but you should watch yet, go swimming should the hair be absolutely tied up and if you use hair products like oil, it should be evenly distributed throughout the hair. Applying it for example only at the tips, you lose here faster color and they look lighter.
Advisable for increased durability is the additional use of the products Prepair and Lock.
I love the bright red simple and can therefore overlook the little flaws, they will therefore continue to use.
