Zuvi ColorBox Review: A Hair Dye Printer That Struggles

I will say that I think this product could be neat in a few scenarios. If you like to dye your own extensions, or you continually change the color of a streak and don’t need to buy oodles of full-size dye containers, or you’re a parent with kids that are always dip-dying their bleached ends, then it might make sense. And the resulting product does smell good. I also like the included container that lets you store leftover dye. If you’re specifically seeking washed-out, pastel tones, I still think you should just … get some hair dye and dilute it with conditioner.

In the end, based on my assessment, the product fails to do its job. And even if this improves—even if eventually, you can get a black pigment to help darken the shades, or Zuvi moves from using primary colors to using cyan, magenta, and yellow, or the company starts making the process of bleaching your hair at home easier, or the use of generative AI stops and Zuvi starts actually standing behind its own results … at the end of the day, you’re still left with a proprietary machine that uses proprietary cartridges, all of which will become paperweights if the company folds.

I’ve combed through every single result I can find of other reviews on the Internet. I’m not a licensed cosmetologist, but I have been coloring my own hair for around 20 years, and I have yet to see a result that’s more impressive than one the user could have achieved for less money from their local beauty supply. Semipermanent fashion dyes are available in hundreds and hundreds of shades, all of which can be mixed together. It may take some trial and error to dial in your perfect pink or blue or red, but it can be done without a machine. Your local beauty supply store likely has an associate who’s been dyeing their own hair for decades and would be happy to point you in the right direction. And respectfully, if you can’t figure out color theory or add conditioner little by little to dilute your own dye, perhaps you should go to a professional and save yourself the trouble of doing it incorrectly. The Zuvi ColorBox adds more guesswork instead of taking it away.

While I do like the initial low price, color corrections from a professional are very expensive, and the refill cartridges from Zuvi (around $22 each) could easily cost the same amount as the supplies would for dyeing your hair with products from the local beauty supply, especially if your hair is long, thick, and/or curly. And I like the idea of reducing leftover dye waste, but again, you don’t need to buy a gadget for that.
