Did you use Dulhan's mehndi henna or mehendi henna? There is a difference. They make a henna for body art (mehndi) and mehendi henna which has different herbs in it to produce a darker result. I hope I got the spelling right on them. I bought mehendi from another brand, Gobrej I think, and I got results similar to your's. It had a real tinny smell that I suspect may be from metallic salts. I was thinking about Dulhan's mehendi because I want browner results and I've only heard good things about this line until your post.
