REPOST from another thread:
I need some advice. My mother was impressed with the results I've gotten from henna, so I started applying treatments to her hair, too.
She is not satisfied with her results after three treatments. She has very coarse, resistant gray hair which is now deep burgundy and rust color. the first treatment was just henna+coffee. The second two were henna+indigo, one-step process, because she doesn't want black, she wants brown hair.
So what can I do now? She is ready to give up and use a permanent chemical color over the henna. Is this safe? Should we do another henna+indigo?
If it makes a difference, I ordered the henna and indigo from henna sooq, so Khadija if you have any suggestions, I'd love to have your expertise.
