My sister and I decided to take the plunge with box dye, and after reading a ton of your recommendations on my last post about the perils of at-home box dye, I took all of your comments to heart and asked my sister if I could dye her roots next time. I asked because she has slightly darker hair than mine, which means her roots are more visible (sorry sis!) and therefore we would be better able to tell if we could combat the number one issue with box dyes: that is, that roots are categorically treated the same as ends, when they shouldn’t.
My sister’s hair is naturally thick, medium-to-fine in consistency, and she has a lot of it! She says that her hair tends to frizz in high humidity. She’s been dyeing her hair at home for years, always with the squeezie tubes, and finds that her hair color results in a lackluster finish.
