Da Vinci Permanent Hair Colors(3.4oz) (9N_Very Light Blonde)

This is a lovely shade, and we really like the color. However, I wanted to warn people about one potential problem. This is NOT a self-activating dye. When I ordered it, I didn't know I'd need to separately purchase developer before I could try this. Lots of bright dyes are self-contained -- they either come packaged WITH developer, or they don't require developer. It's not hard to find (stabilized hydrogen peroxide) but it's not something I keep on hand for hair care, because I've never needed it before. Maybe it could be suggested as an add-on when people buy this? If it had been suggested, I would've bought it at the same time I bought this dye. Other than that, I'm happy with the color.

I have been dying my hair blue for some time now. I got tired of having to scrub the bottom of my shower with bleach every time I washed my hair so I decided to try this permanent blue color. It worked for me. My hair is now a very pretty blue, I'd say U.S. Air Force blue.Note: I bleached my hair before I added the color. I will try to do my roots without bleach to see if I can get similar results.

I love damaging my hair at 30 vol just for absolutely no color to deposit after 40 mins. I didn’t mix it roughly, I mixed it PERFECTLY. I did everything right. When I washed it out, my hair looked the same. Sending it back and getting a refund cause there’s no way I’m paying for a product that damages my hair and doesn’t color it.

A coworker recommended this color and although it's very nice, it was an auburn color. I was wanting a true, deep purple/plum. So, I had to buy another purple dye to color over that color but it still shows thru quite a bit.

Deep thick color. Didn't break hair. I've had blue hair for about two years. This is one of the best . I used develop 20 . Came out the prettiest Navy blue ever. Perfect for me

I bought this thinking it was a toner...wow, my hair is really really dark purple. Not what I was going for but I can't deny it definitely works, and on 6r roots and 8a ends.

I've been using this product for five years. Holds up well, and makes my hair feel soft and full of body. Does not dry out my hair like so many other products.

Doesn't come with a developer and doesn't say anywhere that you need one unless you read the reviews.
