I finally found henna at Sally's Beauty Supply store. I got the Reshma Femme Henna for Natural highlights which is supposed to be 100% henna and Reshma Femme Henna Natural Burgundy which has other ingredients. I'm aiming for a burgundy or auburn color but I'm not sure whether I should try the 100% henna because im not sure how it's gonna come out or the burgundy one which is the color I'm hoping for but it has additives. By the way, I have black hair but some of it has lightened up into brown and some kind of coppery. Any ideas? And has anyone used this brand before? Im thinking of testing it out in the underlayers of my hair or streaks like highlights.
