I'd have one if I could figure out where you read that. Can you give me a link?
Here is the ordering page for the hennas. The individual pages for each color are

This page talks about the production, and
this page talks about henna in general. The only thing that even looks like "This henna washes out" is this text on the last page:

FAQ from hennaforhair.com, about BAQ henna:
So Catherine is more optimistic about the staying power of henna than LUSH, but even she says that washing will "degrade" the color.
Speaking from experience, I've been using LUSH henna for almost a year now, and it certainly hasn't washed out of my hair. I only henna it once a month or so, so the new grey hairs at the crown do get a little lighter; but they don't go back to being grey, and the color on my length isn't going anywhere anytime soon.
People who don't want to use it shouldn't use it, the end. I use it, I love it, it works, it's messy but a lot less trouble than regular dye, and it's done great things for my hair. I look at all the things the people on hennaforhair.com go through with BAQ henna, trying to get the mixes right and deciding on one-step or two-step and adding in every flower and essential oil God made, and I would never in a million years go through that much hassle to color my hair. I'd go back to drugstore dyes first. Fortunately, LUSH has a nice convenient brick of henna that gives me results I love, so that's pretty much the end of the matter for me.
