Review (5/5): UPDATED to previous:  Right color on the box, wrong color product
I received a color that is definitely not dark brown, but rather maybe a light brown (I still have a couple capsules from previous purchase), even though the box identified it as Dark Brown. The powder is sort of a dirty blonde color. The box is simply 'closed', but not manufacture-sealed.
UPDATED: I requested a replacement and the product was the same as the first one, so I tried it. Event hough the powder is very light (unlike my previous purchases), it changes color and darkens after a minute of being mixed with the developer. Indeed the dye is dark brown, and, it seems to take less time to dye the hair and for whatever reason, it doesn't need reapplication as frequent as my older version. Great!
