Real People, Real Henna: "Dorion"

Dorion's color after several henna applications

I'm finally happy with this color after doing it once a month for 4 months. It gets darker each time, and the gray is no longer a problem. This is what I used.

100g of henna in a mildly acidic liquid mix. After dye release, I applied the henna to my hair, but I only keep it on for about 3 hours; more than that made my hair too bright a red for my taste. I use a plastic cap with a wool ski hat over everything to keep in the warmth.

I'm going to continue this every month so the gray never reappears. I hope this helps some people who are looking for ideas.
