Review (3/5): Depends on your hair color & product is small
It is very small (other reviews have photos so I don't feel the need to post one myself). This will only make your hair yellow if your hair is very light. If your hair has any brown tint, it may look like a slight green when you put it on. I expected the product to not be A+ when I bought it. Overall, if you are looking for a vibrant yellow color on your hair with this product, your hair will have to be basically bleach blonde or white. If your hair is light or blonde, it will come out a little pale. You have to go over the same strand multiple times but it works okay.
