I can only agree with the positive reviews !!! This Henna works for my gray hairs super, the somewhat peculiar smell (which does not bother me, only my husband :-)) goes to the second shampooing. I have naturally curly, and how even then, at 17, I have today, with 37, feel that my hair by the henna stronger - and beautiful - be. The hair shine even more and look more voluminous. Before, I used that henna product that is provided with a chemical additive. Today I am glad that it also goes without. Khadi convinced me real! When I turned gray, I thought so, that's it then probably with the henna dyeing (gave me all the hairdressers at least persuaded). After several years of chemical dyeing, pregnancies and thus hair loss I was really frustrated by the chemistry - my hair fell out (even long after weaning), were weak and during dyeing itched my head (I tend to eczema). I tried it but then again with henna - and it works! I always mix several shades of brown and give more recently, some red to. Looks great! In addition, I give a few drops of hair oil Khadi for henna black slurry to the conditions the hair in addition. Oh, and an added bonus: Since I dye with henna, scales are history !!!
