Response to use of henna:
I am allergic to permanent hair dyes, so began using henna and indigo about 10 years ago.
Had been losing hair due to menopause, cancer and then lupus. Found all kinds of herbal, oil and lotion concoctions to use, but the henna followed by indigo---my grey is so resistant, I need the 2 step dye process--that supplies the magic.
After using these totally plant-based ingredients on my hair, hair volume is incredible. Plus, henna is considered a treatment for hair as much as a dye, and my hair has never been softer or a more stunning color from the two plants. Sometimes add Amla to the mix to vary the color just a bit. Great stuff, make sure you are buying everything pure. There should be nothing but henna in your purchase, unless they sell the henna and indigo together for you, which I find does not work for me, but does for many.
It is a commitment of enormous time to dye, but wow, the results are so worth it.
