Can I re-use my Splat hair color that's been opened for a couple months now?
I have kept unmixed leftover hair dye in a small container for four weeks and everything went well. This time, I accidently left it out on my dresser and the light was on. The top portion of the dye turned dark on the top.
The original container for these dyes is usually a dark material. If your container was dark, you can keep it. If it was clear, I would discard it.
You could remove the top portion that turned dark and see if the rest of it is good.
The best way to tell, of course, would be to test it on something that you didn't care about - I suppose if you didn't mind cutting off an inch or so off your hair, you could test it
I am sorry but I just do not understand why you would want to take a chance on damaging your hair over this amount of money.
If there is even the slightest chance that it would not "react" the way it was designed then it would be best to discard it.
Please - Try reading all of the cries for help where people have made mistakes with even "safe" hair dye before you decide to use this mixture.
I just looked at the directions on a box of mine. It clearly states to discard any remaining. My husband worked for a chemical company for over 30 years. He read the ingredients and said it is dangerous to keep around after it is mixed and it changes chemically after long exposures to air. Dump it out.
You can save dye that has not been mixed with developer. I mix two different colors, so I always have some leftover. Once you mix with the developer, it must be thrown away. The way I read the question, the unmixed dye changed color, so that's why I advised her to throw it away.
If only just the very top portion has darkened, say a tenth of the amount in the bottle, the color should still have most of its potency, and should give the same results. The darkening is caused by oxidation. The top layer of color is exposed to the air in the bottle.
Use of this leftover color is safe (providing it hasn't been in contact with any developer), and again, should give the same results. In the salons where custom colors are mixed, there are thousands of half full bottles of color returned to the shelf every day. These may be used a month later on the same customer with the same results.
While this is common practice. It has its limits. A good colorist keeps strict account of his/her color inventory, knowing which leftover colors will produce results identical to the original, and which ones should be discarded.
If you keep your leftover color in a cool, dark place and tightly capped, it should be OK a month later. I would not advise keeping it longer. You should know that the lighter the shade of color, the quicker it will deteriorate. Also, if the color comes in a plastic bottle, you can squeeze a good amount of the air from the bottle before returning the cap. This will help prolong the shelf life.
At color shows, I have seen professional colorists from Roux and Clairol set aside a half full bottle of color for use some time later. When they opened the bottle, they stuck the inner seal to the outside of the bottle. Before resealing the bottle, they replaced the inner seal. They said this would help keep the potency of the color while on the shelf.
I agree with Judy. I would not attempt to keep color in a clear plastic bottle. Both light and air degrade leftover color on the shelf.
I'm sure when Judy's hairdresser told her color had a year shelf life, she was talking about unopened color, though some of the darkest colors, after opening, will probably keep well (under ideal conditions) for 6 months.
As for the shelf life of unopened color...I have a near full tank of Roux fanci-tone #11 blue jet. The unused contents of the tank have never come in contact with air, so they qualify as 'unopened'. I recently dispensed a few drops to test. The color had all the potency it had when it was purchased. It was purchased 50 years, ago.
I would not use the dye. The directions clearly indicate to throw away any unused portion. These are chemicals and te chemical reactions take place may very well be dangerous.
The directions are talking about throwing away unused portions that are mixed with developer, not unused dye that has not been mixed with developer.
I've never saved the leftover hair dye as it can affect your skin and could cause rasher etc, but if you havent mixed it you can keep it but keep out of the sun place it in a cool place
Can you use the same hair dye from the previous day?
Hair dye, unmixed, has a shelf life of a year. Once you mix it with developer, you must throw away the mixture. You cannot even use it one day later.
Can I use only a little amount of and how do I preserve and store the remaining dye for future use?
It is my understanding that any dye that has to be mixed unused/leftovers should be discarded.
I realize it is expensive and having to discard a lot more than you use, seems very wasteful. Always read the label with products like this as when using chemicals it is very important to follow directions exactly as stated.
Perhaps you could use a semi-permanent dye that does not require mixing?
Check directions on container but I believe you can store unused portion in dark well sealed container (room temperature) for several weeks.
This is not a permanent dye so it will fade faster but you can easily reapply when necessary.
I color my hair and have a lot of solution left over, as I have short hair. Is there anyway I can use this bottle again when I need to dye my hair again? Thank you.

I have short hair as well. I just mix 1/2 the solutions and use either another bottle or a glass cup and a hair color brush. Works great for me and I always get 2 applications per box. Just be sure to measure right.
Hi Flower
I too have short hair and I have used 1/2 the solutions to color my hair for years. I am not "dying" my hair but "bleaching" it as I use blonde shades. The creme developer and the permanent hair color in the kit are both 2 oz.'s so I measure out 1 oz. (2 Tablespoons - use plastic , not metal measuring spoon) of each and mix together and get 2 uses out of each kit. As I have done this several years I kept prior application bottle to mix and apply my "saving" mixture. Happy Good Hair Days!

You must do this the way the other posters have suggested. You can not save the solution after it is mixed together.
what do i do with left over dye in tube were do i throw it away
I was wondering the same thing. My hair dye I bought over the counter says it may bursts. I have a quarter of it left and I was wondering, do I just through it in the trash? What if it bursts in my bathroom trash can? What a mess that would be. Just so I know for next time. I read ALL the instructions and never came across exactly what to do with any left overs. Thanks in advance!
I thought I needed two bottles of Loreal casting creme. I have already mixed the developer and the creme though I have not used the other bottle.
Since I already mixed it can it still be used in the future? Please advise.When my mom dyes her hair, she mixes what she needs and saves the remaining unmixed.
However, I believe it says if mixed - it has to be tossed.
Reference online many also say once mixed - it should be tossed out.

If it's already mixed, you must empty the contents and dispose of it. It can balloon up and pop if you just leave it sitting (mixed together) in the bottle. That happened to my friend.
If you have added the developer to the dye it must be discarded. You use equal amounts of dye and developer, so just mix what you need next time.
No, it should be pitched. It will have fumes to it that build up pressure and can split the bottle open.
You cannot use the saved hair color later. It has been oxidized and useless after a couple of hours. Toss it and buy a new bottle for your next re-touch. There is no way to even re-cycle it into something useful. Sorry to be the bearer of bad news.
My tube of hair color is enough for 2 applications. It has a small hole in it. Is it safe to use the rest?
Can I use my permanent hair dye after 3 weeks in the fridge?
Can I keep hair coloring if I only use part of the bottles that you mix together. I have short hair and don't use all of the product. And I was wondering if I don't mix all the product, can I use it later? And if so how long can I keep it?
By Esther
I have done it by not mixing it all and saving and it was fine.
The product that I use says that you can do that, as long as you don't mix the products together. Once you mix them, you have to use them up or toss them. Read the package insert, and it will likely give you details.
My hair is short, I do not use all my colour mix at one time, I keep half back that is not mixed. I also do this with my permanents, enjoy saving a little money.

Yes, you can keep unused permanent hair color as long as it has not been mixed with a developer, such as peroxide. How long you can keep it and get satisfactory results, varies. Darker colours tend to keep longer than lighter colours. Both leftover color and developer should be tightly sealed and kept in a cool dark place. A refrigerator is best.
To insure a good colour 'take' and a good colour match to the already coloured hair, I would suggest you use the leftover colour within four to six weeks.
How long can i keep my hair dye as long as i dont mix it all up for???
Last night I dyed my hair and I missed a spot. My hair is short so I still have a lot of dye left. Is it okay to use the next day (it's Feria in deepest violet)?
How do I divide a tube of L'oreal hair dye evenly in half so I can use it twice? I only need to use half of the ingredients for each hair dye using L'Oreal Excellence. The coloring creme used to be in a dark bottle that was easy to divide in half.
Now it is in a tube so I cannot tell if I have squeezed out half or more or less. Each tube says it holds 1.86 fluid ounces. How can I divide the contents so that I use half and save the other half for the next time.I have bought Loreal's Majirel hair color. When I opened the box, the seal of the tube was missing and when I squeezed it, the hair color that came out was of green colour. Is this colour useable or should I throw it away?
Why do I have more hair color than the chemical when I use a partial bottle? It clearly states ie 30 ml of both bottle contents?
I want to know if I can use semi permanent hair dye 2 days after opening?
I did a transformers test on my hair and left the bottle out over night. Is it still OK to use, will it be as effective?
Can I use the Ion hair dye from the tubes after opening it?
What, other then the original bottle, can I keep unused unmixed developer in to save it for another time?
I have hair color and peroxide mixed as leftovers. Can I put them in fridge to reuse 6-8 weeks later? Thanks.
I only dye my roots to cover up my gray with black dye. I had a bunch left over and put it in the refrigerator. Is it still safe to use on my roots? It's been stored for about a month.
