Hair turning green. Is it always permanent? Can it be avoided?by ZupergoddessPosted 1 year, 8 months ago
I recently got really hooked on hair dyeing. But I've only done different shades of pink and peach. I really want to try other shades as well, like aqua, blue, purple and yellow, in particular. From searching online, I've gotten the impression that all shades of blue and purple turn your hair permanently green. I get that the blue fades green on blonde hair, I could stomach that when it's washout, but permanently? Not so much. So, is this something that always happens? Or does it depend on the brand? Or something else? One thing that I cannot find any information on, is how to avoid it. There's loads on how to get rid of it, but is there any tricks to avoiding the green hair in the first place? Thanks in advance. Still very new to this, so correct me if I'm wrong on any count :)

There's certain brands and even sometimes certain colors in certain brands that would be easier to remove than others. If you snagged a more purpley blue then you're less likely to get that green color you're talking about. Avoid any ion brilliance blues bc they're close to permanent. Special effects is my favorite brand but it's highly pigmented and can be difficult to remove. I'm mentioning it though bc a color like electric blue, which is a very purple based blue is more along the lines of a purpely blue in order to avoid geeen. That will fade to a lavendar/grey. If you diluted some electric blue with conditioner before applying it I think it would be easier to remove. Manic panic also has some good blues but I'm not sure which one would be best. Rockabilly blue is amazing, can be tough to remove, but might be alright diluted w some conditioner. The big thing you want to avoid is any majorly green based blues,like teal or aqua.

Agree with my colleague ION is close to permanent, some other brands are also close to permanent like Splat. Most brands are not permanent.
There are no tricks to avoid blue hair turning green for most brands simply because we live on a planet with atmosphere. This atmosphere contains tiny particulates that cause hair to yellow. Most easily seen this yellowing on white hair. The atmosphere also contains the most particulates the size equal to the blue wavelength of light. Thus blue light gets scattered the most and the reason we have a blue sky. Without particulates in the atmosphere to reflect light we would not be able to see.
So the yellow particulates and blue make green, and most brands of blue in hair slowly turn toward green. There is no way to avoid science. However suggest a purple based shampoo which might work for you. Purple based shampoo hides or masks the yellow in white hair like Shimmer Lights or So Silver or Brass Off.
Some purples are red based and when they fade will turn the hair pink. Other purples are blue based and will fade toward blue.
This is my humble opinion and suggestions based on nearly 30 years with semi-permanent dye as a non-professional and as a professional scientist.
