I combined 100 grams Reshma Henna with about 50 grams Amla powder which is a great conditioner. I also had a little Moroccan Henna leftover from my Hennasooq.com order so I figured I would use the rest. The resulting color definitely covered my stubborn greys but was still very burgundy red. Indoors it still looks dark but you can really see the red tone in the sun. I was hoping for a different result because amla is known for darkening but, oh well.
On other occasions I combined Indigo with my Henna for a brunette color. Somehow I was still ending up with a more reddish auburn. I may end up going black by applying the Indigo to my hair after I’ve rinsed the henna. I’ve heard that this 2 step process will also give the best gray coverage. Either that or I’ll give the henna/indigo mix one more go but this time using more indigo.
