How to prevent blue dye from turning green?

After knowing how long does blue hair dye last, it is good to know how you can preserve it. To keep your gorgeous blue hair at its best, there is a slew of tactics at your disposal.

1.Use Purple shampoo

To neutralise the yellow undertones in your hair, try using a purple shampoo. When blended with the blue hair color, these yellow tones can result in a greenish tint in your hair. 

  • After washing your hair with your usual shampoo, apply a considerable proportion of purple shampoo to it.
  • Allow the product to rest for a few minutes before rinsing. A decent rule of thumb is to wash your hair with this shampoo once or twice a week.
  • Hair that is a lighter shade of platinum blonde may not appear as green over time as darker locks.

2.Take a chilly or lukewarm shower.

When it’s time to get wet, don’t turn up the heat in the shower. The outside cuticle layer of your hair is lifted by hot water, which is how fading occurs from a scientific aspect. Set your water temperature to a lukewarm or cold setting to keep your hair color from fading as quickly. The faster your color fades, the higher the water temperature.

  • A deep conditioner with a blue dye can rejuvenate hair color.
  • Fill a clean, empty jar about a quarter of the way with a deep conditioner and shake it well before using.
  • Using your conditioner, mix in 1 tablespoon of blue, vegetable-based semi-permanent hair color.
  • Use a comb to distribute the colored conditioner throughout your hair while you massage it in.
  • After that, remove your hair and allow the conditioners to sit for five minutes out of your face. After rinsing the mixture, dry it thoroughly.
  • To keep your hair looking its best, use this mixture in the shower.

3.Make sure your shampoo and conditioner are sulfate-free.

Sulfates can deplete your hair of its natural oils, colored color, and hydration. You can avoid this by checking the labels of your shampoo and conditioner at the store. Sulfate-free options are available, and previous products that list sodium laureth sulphate or sodium laureth ether sulphate as an ingredient should be thrown out for good.

You can also check for products branded specifically for hair that has been colored.

4.Every three days, apply shampoo

You don’t need to shower every day to stay clean. Every time you shampoo, your dyed hair will lose some of its vibrancy. If you want to maintain your hair’s color without sacrificing its cleanliness, you’ll need to spread out your showers.
