Let the shampoo sit for a while to enhance your results and restore your cool tones. We're not talking too long—even two or three minutes, after you lather, should work wonders.
The amount of time to leave your shampoo in depends on your hair's condition and desired intensity, but the average time is between two to three minutes. However, you can leave it in for a maximum five minutes if you want to deposit more pigment.
Typically, washing with blue shampoo results in an instant brightening effect that can eliminate orange tones for 2-3 washes.
If you leave blue shampoo on for too long (whether you have damaged or healthy hair), you run the risk of leaving a noticeable blue tint on your hair instead of only neutralizing the brassy tones.
Before and After Using Blue Shampoo on Dry Hair If your hair takes color well, do a strand test on dry hair. If you rinse it out and end up with unwanted blue tones, you may be better off applying the shampoo to wet hair in the future.
Overuse of blue shampoo on fine or dry hair can lead to unwanted color buildup or dryness, so spacing out applications is key. Long or thick hair: Frequency once per week or as needed.
After dyeing your hair, wash it with cold water and a colour safe shampoo or conditioner as infrequently as possible. If you want your colour to last, only use water to wash your hair or keep your hair fresh by using a dry shampoo in between washes.
The longevity of blue hair dye varies depending on several factors, including the shade, your hair's porosity, and your hair care routine. On average, blue hair dye can last between 4 to 8 weeks, but it may fade gradually over time.
You'll leave the shampoo on for 5-15 minutes before rinsing with cool water if your colored hair has been recently dyed or is discolored. If it's your first time trying purple shampoo, experiment with leaving it on for only 5-10 minutes before washing it out.
The Bottom Line: Use purple shampoo to tone yellow, usually blonde hair, and blue shampoo to tone orange, usually brunette hair. When deciding how to fix orange hair, you might try using a toner to get rid of the orange pigment. Toning neutralizes unwanted brassy tones to reveal a cooler blonde or light brown shade.
Step 2: Lather and leave it to absorb for two to three minutes. Step 3: Rinse. Use the blue shampoo daily until brassiness disappears. Then, alternate with your regular shampoo to maintain the results.
If you leave purple shampoo in your hair for 30 minutes, the risk of over-toning increases significantly. While purple shampoo is designed to neutralize brassy or yellow tones, leaving it on for an extended period can lead to overly cool or even purple-tinted hair, especially for those with light or porous hair.
Neutralizes brassy tones in all shades and adds silvery brightness to gray hair.
Grab your Aussie blue shampoo, dab some on your hand (we really recommend smelling our Australian Plum & Manuka Leaf fragrance first to maximise your pleasure) and spread it evenly on your tresses. For a stronger effect, you can leave it in your hair for three minutes before rinsing.
Hair Color: Purple shampoo is ideal for blondes and highlighted hair, while blue shampoo is better suited for brunettes and dark hair with unwanted warmth. Strength: Blue shampoo can be more powerful than purple shampoo because orange tones tend to be more stubborn.
While blue shampoo is good for brown hair, it is important to know which type of product you are using as you may not want to overdo it. This can lead to your hair turning darker than you intended, so it's good to know the limits.
Gently massage blue shampoo into wet hair. Lather and rinse well. For more intense results, and to fight brassiness in brown hair, leave shampoo on your hair for 2-3 minutes. Use daily until your desired color result is achieved.
One downside of purple shampoo is that overuse can lead to a purple or violet tint, especially if left on for too long. It's important to follow usage instructions to avoid this issue and to ensure the best results for your hair.
Level 2–3 is extremely dark brown, as level 1 is black. Level 9–10 is very pale blonde. Color does not lift color; only bleach can make your hair lighter.
In case you do leave hair dye on your hair for too long rather than rinsing it at the recommended time, you could end up with a hair color that is much darker than the color you were hoping for. Even worse, your hair might end up brittle, over-processed and unnatural looking.
Darker hair colors like deep black, espresso brown, and blue-black tend to fade the slowest.
If you're really ready for a new shade and you're not in a hurry to go back to blonde, vivid pink and purple Super Cool Colours are great for transitioning away from blue. The Big Pink is a favourite, but you can also try Burnt Peach, Gobby Pink, I Saw Red, Bruised Violet and Aubergine Dream.
Jesse says you'll have to touch up a color about every two months to maintain it. To make this less necessary, he recommends a toner and color-safe shampoo. You can also use a color-depositing conditioner, says Kiyah. (The Davines Alchemic and evo Fabuloso lines are particularly good for this.)
To keep your new hair colour vivid and bright, we recommend washing your hair with cold water (as cold as is bearable). Cold water keeps the hair cuticles closed and therefore stops the colour running out and fading too soon. Warm water is the enemy!
If you have little or no warm pigments in your hair, the ash colour can give your hair a green tint. The same can happen when your hair is bleached or de-coloured. Here too, the problem is that there is little or no warmth left in the hair and thus no red pigment that can neutralise the green/blue pigment in the dye.
