Appy Luvr your crested is adorable! I love her(?) hair (not the pink, her just her hair in general), I wish my girl's hair was that nice and full! Here was my attempt to color my cresteds hair, I wasn't overly in love w/ the product, it was kind of like hair spray and couldn't do much w/ it after it was on, so not sure I have much to contribute.
I met a dog groomer a few years ago that had recently dyed her daughter's poodle pink. She gave me the cataloge she'd ordered the stuff from, but I'm not sure where it is now or what the stuff was called, she said it was pretty good stuff, but you have to wait for it to wear off, so you'd have to not mind leaving the color for abit.
Lol, love your CC too!!! I raise them so I have several different hair types but Bianca is by far my prettiest!!! I tin foiled her just like they do to you at the beauty shop, that's how I got hers so neat!
I may have to try that, it is really beautiful, and Bianca is really beautiful! Zoe's isn't looking that great right now, she rubs it and ends up breaking the hair just around her face leaving the hair really short, but she doesn't have as much hair as your girl anyway, I'd sort of like to let her ear hair grow, but I just can't stand the inbetween stage.
