So I have just ordered some henna that will, if all goes according to plan, dye my hair a lovely strawberry blond. I'm a redhead right now, done with chemical dyes about four months ago. I have read all the memories on Henna and know not to use the lush henna bars (my brushable hair would have loved all that coco butter), so I ordered the pure powder henna to mix my self.
But there are a few questions I still have not answered in the memories.
1. Has anyone every had a green hair disaster after using Henna on chemically dyed hair? In the memories it said that this can sometimes happen but I didn't read any personal accounts of anything like that happening, and I really don't want green hair.
2. I also read in the memories that if you use cling wrap it can affect the color of the dye (the example was specifically about brown dye). Does anyone know how using cling wrap will effect the color of the reddish blond dye? I'm going for more of a blond and less of a red.
3. How long after dyeing with Henna would it be "safe" to do a deep clean? my dreads are only two month old babies and I have very naturally oily hair. The first deep clean I did (baking soda) worked wonders to get all the grossness out of the center of my dreads and I'd like to do it once a month, but I'd also like my color to stay as vibrant as possible for as long as possible.
how does one determine if a shampoo is "residue free"?
