Very good

I used the product on a 634 base, worn to remove some residual yellowish and orange tones, to mattify tone 6 and leave it more neutral, apply it to shampooed, rinsed and towel-dried hair, let it act for 5 minutes, and rinse with plenty of water. I could notice that it had shaded the unwanted orange and yellowish tones and had left them much softer. It really works, but it shades them a little so that they are not as visible, nor does it remove them completely, for me it was obvious, and it did its job, so I give it 5 stars
