Is this stuff seriously THAT undetectable? I might have to use some in my crown if I spike my hair. If you use hairspray and it gets wet, is it going to be dripping down your head like paint/shoe polish? ::;mb
The lower part of my crown has darkened & thickened markedly from meds, and I thought the upper part has too, but it seems thin lately. I'm hoping it's just a shed & will re-grow thicker...time will tell.
