My red hair started going gray in my mid-20's. I've used red henna for probably 20 years, but as my hair has lost more of its own color (it is now all gun-metal gray with patches of white) it has started to look orange-y with pure red henna.

So over the last couple years I have started adding larger and larger proportions of brown henna to my red henna. At this point I use mostly brown henna, with just a bit of red mixed in.

I've used the same brand of Henna ("Light Mountain" http://www.light-mountain-hair-color.com ) it seems like forever, so I'm pretty confident mixing and matching my own henna recipes. My hair chickie (who has been cutting my hair since before I started dyeing it) says that when it goes totally white I can keep the color perky by dyeing first with red henna, then dyeing over it with brown.

Quite honestly, if I end up with the same lovely hair my grandma had, I won't dye that.

Eden - I'm very interested in how your hair turns out!
