gosh, no. dd has spirally curls, i was most surprised by the fact that if you get the angle right it doesn't tug at all. i know this... because of course i've been using the blessed thing myself. you certainly can't use it like a normal comb or brush, though, and i did think it was a bit short on instruction.
Its brilliant! I ordered, the solution, and the spray, but forgot to order the actual comb. I rang them to say the comb wasnt there, and they said, you didnt order it! but never mind, we will send you one free of charge anyway, and they did, and it was with me already the next day!
(sorry cant punctuate either afer a carton of wine)
