Wren wanted horse/unicorn cakes two years in a row. We ended up drawing a unicorn on a sheet cake this year but if she wants one again next year maybe I'll do this, since I think I like it better than the horse's head I made last year.
Liked it because it madenmy hair extremely shiny and soft. didn't cover grays, but I only did once and the instructions suggested two days in row to be more effective. I am about to do again with darker roast coffee to see results :-)
