Where can I get a henna tattoo in North London?

I tried to find some shops, but I’m not sure which is nearest to me. I’m in West Hampstead. I went to Camden yesterday, but the two shops near the underground Station do tattoos only, not Henna

Maybe some Asian areas? Eg near Kingsbury station. I think beauticians do henna (rather than tattoo people).
