I recently did the 2 step process on my 80% gray hair. I have previously used a demi-permanent color on my hair about 5 weeks ago. I applied the henna with no problem. When I applied the Indigo and left it on for about 45 min. I started getting a headache.  Now 3 days later I have a rash on my neck where my hair touches it. 

The color is a medium brown which I am happy with but now I don't know how I can maintain the color w/o using Indigo to hide the gray roots.   I did not use your products. I am  hoping this will fade.

I am definitely a newbie.

Any suggestions?  :(

Thx!
