did not work for me [SEP] let me begin this review by stating that i have been using egyptian indian and pakistani henna for over years with beautiful results that lasted a full months i decided to try this product because i wanted a change from all the red highlights and thought it would be nice to tone down to a browner hue i not only followed the instructions to the letter but had several exchanges with the seller to make sure what i was doing was correct the good news is that this combination beautifully toned down the red from all my prior years of using henna only the bad news is that not one gray hair i am dark brown with about gray gave up being gray so in addition to the hassle mess and expense of doing this treatment and make no mistake it is messy and time consuming i will have to double up this month and do my regular henna only routine i did a bit of research by the way and learned that most henna indigo distributors unlike harvest moon suggest mixing up the henna and indigo powders separately and then combining based on my experience i would have to say this would probably work better the rationale probably being the same as why combining shampoo and conditioner together do not work as well as shampooing and then conditioning likewise everyone else except harvest moon recommends wrapping the hair in plastic wrap and then covering with a shower cap and leaving on for a minimum of hours harvest moon says their product works in less than one hour and is against wrapping leaves me to wonder if the gray hairs would not be gray had i followed the advice of the other henna indigo distributors here is a good reference website
