A: I take half of each bottle and mix together in a small Tupperware container where I can mix them up and use on my hair. I put the caps back on both of the half used plastic bottles. I then save them for the next time I need to color my hair. That way I get 2 uses out of it.
No, you cannot save half-used hair dye and use it for another day. Once the hair dye and developer are mixed together, a chemical reaction occurs, and the product becomes activated. This means that the dye will start to oxidize and lose its effectiveness over time.
No. Once mixed, it must be used right away. It stops working after a very short period of time due to oxidation, a result of the colour being mixed with the developer.
Yes, you can mix two different brands of hair dye, but there are some important considerations to keep in mind: Formulation Compatibility: Ensure that both dyes are of similar formulations (eg, both are permanent, semi-permanent, or temporary). Mixing different types can lead to unpredictable results.
Any hair color that utilizes a developer should be used within 24 hours of being mixed - ideally it should be used within 2 hours of being mixed.
Generally speaking though, it's best to wait 4-6 weeks before having another color treatment – in most cases, this is enough anyway and reduces the risk of hair damage. There are some exceptions, but in general, it's better to err on the side of caution and wait for this long.
The best thing to do is to avoid shampooing directly after dyeing your hair. Instead, rinse with cold or lukewarm water to avoid washing the color away.
The best thing about getting creative with your hair colour is that you're not limited to the colour you see on the box, semi permanent hair dyes are perfectly suited to mixing together to form your perfect shade.
Split hair dye is a trendy hairstyle that involves splitting the hair down the middle and dyeing each half a different color. Think Cruella de Vil, but with color. Split hair dye is when you dye half your head one color and the other half another.
“As long as you use the same brand you can mix box hair dyes. Adding a rich red to a brown for example, would be very pretty. Again, USE THE SAME BRAND as you do not know the tonal qualities of different brands, and may get a muddy result.”
Therefore, we should avoid mixing demipermanent or permanent hair dyes with conditioner, (2) as it could interfere with the chemical reaction and can give your hair a patchy or inconsistent color.
Letting hair dye sit for too long
Did you forget the time, or did you fall asleep after applying the dye, letting the hair dye sit for longer than 45 minutes? Don't worry! The hair dye has lost it's effect at some point, and won't have any impact after a certain amount of time.
Store in a cool dry place away from sunlight. Once the colour cream and activator are mixed they must be used quickly and leftovers should be discarded.
You don't have to use everything at once. You can also mix 1.5 tubes first so that you can save the rest for the next time. If you have too little, you can mix in again. But once mixed, you have to use everything and cannot keep the hair dye.
For normal-to-dry hair, that window can stretch up to three days between washing your hair and applying at-home dye. One notable exception is if you're using a temporary, wash-out hair dye. It's typically best to apply these to freshly-washed hair, since they'll only last until your next shampoo session.
The One-Hour Rule for Mixed Dye
Keep the 'one-hour rule' in mind when diving into hair dye adventures! ⏳ Once you've mixed it with the developer, aim to use the magic potion within an hour. Any longer, and you're on the risky side.
Hair color shades can be mixed but ONLY if they are the same type (permanent, demi-permanent, semi-permanent) AND the same brand.
Part hair down the center of your head starting from the top all of the way to the base of your neck. Clip the half of your hair that you are dyeing second to one side starting from the base of your neck, using more clips as needed to make sure the hair is secure to one side.
A common pitfall that many people fall into, and should be avoided is shampooing after applying semi-permanent hair color. Following your initial application of semi-permanent hair color, it is important to not shampoo your hair.
While leave-in conditioners can be a great addition to your hair care routine, they can also affect your hair dye. That's why it's always better to choose the right leave-in conditioner that can work well with your specific hair dye type.
You can mix two shades, as long as they are in the same product line! For the best results, when mixing two shades, we recommend that the two colors are no more than two shades apart (8R and 8SC are within the same shade range).
Apply the semi-permanent hair color on dry or damp hair. Towel-dried hair will allow it to soak up the color better. Spread the color evenly onto the desired areas. Make sure that you carefully follow all the directions of the application as mentioned in the instructions.
Dye residues left on the scalp can cause itching, redness, or even more severe allergic reactions. Washing the hair immediately removes these residues and reduces the risk of such unpleasant side effects.
As our colours are semi-permanent we do recommend that your dye is left to process for 30 minutes minimum but you could leave it on for a couple of hours if you wish. Applying heat to hair dye that is processing can help to open the cuticle of your hair and allow it to absorb the colour a lot more easily.
