The short answer to this question is yes, but this question deserves more than just a one word answer as there are a lot of things to consider when using green hair color on black or very dark hair. The first tool you’re going to need in order to make this happen is dedication. Are you willing to go through the effort it’s going to take to keep your hair green? Because black hair is so dark, it will be very difficult to get it to a green color directly simply because the black would override the green. What this means is you can’t apply green hair color directly to your black hair and expect for it to be a good green hair color once you’ve completed. If you had very blonde hair you could do this, so with that information what it means is that in order to make your black hair a good quality green color you will first need to bleach your hair to blonde. For this reason many people who have black hair stay away from going to a green color because it’s so hard on their hair. Not only will you be bleaching which isn’t good for your hair, but then you will be applying more chemicals to your hair to apply the green color. At the end of the process if you don’t do it correctly you’ll have hair that looks very damaged and worn out and you may regret ever doing it.
The good news is if you have the dedication and the time, you can use green hair color to color your black hair green and still have it end up looking good. One of the keys to this is buying high quality coloring products that reduce the amount of harmful chemicals you’ll be putting in your hair. A popular product called “Sun In” is a spray bottle that bleaches your hair by spraying bleach type chemicals directly on it. While this will help turn your black hair blonde before using the green hair color, it’s also not healthy for your hair and isn’t recommended. A good high quality example of bleach for your hair is L’Oreal Platinum. You can find this in almost any store that sells hair dyeing products and can expect this to be of higher price than most other products. This is because the ingredients used in the development promote healthy hair and will cause much less damage to your hair once complete. It’s well worth the money if you want your hair to look nice, which is a given since you’re looking to dye it green!
Keep in mind that regardless of how high of quality the product you use in your hair is, you will be damaging your hair. It should also be noted that bleaching black hair is permanent, so don’t expect the color to simply fade out of your hair with time; you will need to actually grow it back out in order for the bleach to be gone. Once you bleach your hair a nice blonde color (be sure to follow the directions for your specific brand, every bleach is a little different!) you can then begin to look for green hair color. Once again, go for high quality products. A good green hair color product can be found at Hot Topic. Special Effects is also a good quality green hair color that won’t completely destroy your hair. There are less expensive ways to go, like creating your own, or sitting in the pool too long…but it’s not recommended! It’s also a good idea to wait a couple of days before using green hair color on freshly bleached hair. It can be very hard on your scalp and hair and you should give it time to repair by using warm water and really good shampoos and conditioners.
If you have dark hair and are looking to use green hair color on it, take your time and buy high end quality products and understand that this is permanent! While the green hair color may fade, once it’s gone you’ll be bleach blonde again until your black hair grows all the way back out. Have fun!
