I am so happy I found Kelly Van Gogh haircolor through Birchbox. This is the best at-home hair-color I have ever used, the results are amazing.
A kit costs more than anything in the drug store, but is less than half of what I pay at the salon and the results are better and more natural than any salon color I have ever had.
I have dark hair so I use the Medium Neutral Brown 3N and my haircolor looks like it did when I was in my teens. It appears full, shiny, and healthy for a solid 6 weeks, but I could go 8 to 10 weeks before a touch up.
