For some reason, after using shade 600 for eight years, since 2017, with the new formula, they’ve changed the color; it’s much blonder. If they make this kind of change, the least they can do is notify the customer and offer the option of finding the same shade they were using... now my hair is yellow and I look awful. Also, since my hair is very delicate, I can’t dye it again right away... I’m really disappointed. I used to recommend the product, but not anymore.
