I recently purchased the Ancient Sunrise chai kit for blonde hair.  I am considering adding amla to the mix to prevent loss of wave in my hair.  I have ash blonde hair with natural golden highlights from the sun and just a little wave to it.  I do not want to loose any of the wave and became concerned when I read that henna relaxes curl.  My hair is very fine and I don't want to lose any body by applying henna.  Should I add amla to the mix to keep or enhance wave?  What will this do to the color if I add it?  Should I mix the kit contents for dye release and then add the amla before applying?  Should I still add lemon juice to the mix if I add amla?  I have never hennaed my hair before and am a little nervous.  I am not sure I want to loose the golden highlights or the little body my hair has.  I wanted to add some red highlights and body.  Any advice?
