Schwarzkopf Color ULTIME Rich Brown 4.1 worked great. I was hesitant to go with a brown since I normally use a red color. Since I had lots of roots that were grey, I opted to go with the direction suggestion of doing the roots first. I did the roots and left them for a good part of the time. I used 3/4 of the product for the roots. Since I still some reddish color on my ends the rest of the bottle was used for the rest of my hair. I was surprisingly impressed with the product as it to not has a bad order. It was extremely easy to use. Although I found the color darker than I expected, I still liked the color this brand provided. This is the firs time that I used a Schwarzkopf Color ULTIME Hair color product. I highly recommend this product....next time I would try a lighter brown or something with a reddish tint. Overall a must try product.
