How Often Do you Henna?

Just a question to see how often you henna. I am going to henna my hair with Dulhan Henna Mehandi Powder this weekend. I colored my hair Jet black about 2 weeks ago. I started researching henna and wanted to give it a try. Most of the postings that I've read say that they henna every week or every other week. Do I really have to henna that much to keep up the color?

I dp it once a month but this summer I will do it once a week. I just want to see what will happen if I do it often.

Once a month for me too, due to time constraints. You can do it more often and in fact when people start out they often do frequent hennas to satuate the colour before eventually spacing it out. If your hair is already jet black then you probably won't see much change apart from conditioning benefits. There is nothing wrong with doing it once a month.
