What to Look For When Purchasing The Best Green Hair Dye

Best Green Hair Dye

1. Brand 

The big brand names tend to be higher quality than the ones you’ve never heard of. This isn’t rocket science, but we are talking about a chemical that is going to drastically change the appearance of your hair, so it’s probably better going for something well-known, over a brand which is unknown.

2. Cost

A cheap green hair dye is probably not going to give you the best results, because the chemical content may be lower, or of lower quality. If you go for a middle priced product, or even a higher priced product, then you can expect better results overall.

3. Shade of green

Do be aware that every shade of green is different, and that everyone’s hair will bring about different results. If you have a certain amount of dye from a previous effort in your hair, no matter what shade, then you can expect the results to be slightly different than someone who has never dyed their hair in the past.

4. Do you need to bleach your hair first? 

We mentioned about having different shades of previous dye in your hair, and if you do, it might be an idea to bleach or strip your hair first.

This removes all color from your hair and gives an even starting point, but be warned, it can dry out your hair and leave it brittle. Deep conditioning is required in order to keep your hair soft, and to avoid it looking a little too much like straw.

5. The result you want 

Do you want a bold shade, or do you want a more subtle result? In that case you need to look at whether you want to mix shades and create that aforementioned mermaid look, or whether you want a single shade, perhaps even neon! Check out fashions at the time to find new looks to go for, but overall, you need to assess your own hair in order to get the best result.

6. How do you mix your green hair dye? 

This is something you need to consider, as not all hair dyes are the same. It’s always best to follow the instructions on the pack, to avoid any mishaps. You will need a small plastic mixing bowl, which may or may not have come with the box, but if not, use a bowl you’re not too bothered about staining!

If you want to tone down the dye slightly, mix it with a blue tone, to give you less of an intense green and more of that mermaid look which is so fashionable at the moment. Make sure you mix it together well, without any streaks, otherwise you may end up with an inconsistent style, which is less than pleasing.

7. A quick tip to avoid head staining, use Vaseline! 

Apply Vaseline to your head, along your forehead, to avoid a rather strange green hue!

Once you have dyed your hair that wonderful shade of green, it’s important to know how to look after it, to maintain it without fading. One of the biggest mistakes people make is to wash their hair too often.

This strips the color out much faster than if you allow it to settle, and when you do wash it, go for a product which is specifically for colored hair. On top of this, avoid any swimming pools with chlorine content, and you could opt for dry shampoo, to elongate your hair’s wash life.

Drying your hair can also cause color problems, because it strips the color much faster and leaves it faded or looking limp. Wear a hat if you are in a country with a lot of sun, as again, this can cause fading. Touching up your hair occasionally is also a good idea.

To decide which is the best green hair dye out of the products we have reviewed, you really need to take into account the actual shade of green that you are wanting to achieve. Of course, you can mix most of these products with blue hues to give a much more muted result, but if you don’t have the time or the know-how, it’s important to get the right shade from the get go.

In terms of salon quality, the Splat Kit Neon Green product is a great option, because it is easy to use and comes with the mixing container and everything you need in the kit.

 This means you don’t have to try and find a box or tub that you’re willing to be stained! This particular product is a bright neon green, but if you’re trying to find a muted, darker shade then it has to be our final review product, the Manic Panic Semi Permanent Hair Dye.

This comes in a ready mixed tub, which is ready to be applied to hair – for that reason, if you’ve never dyed your hair before, you can’t go wrong with this particular option, as well as being a more darker, muted shade, for those who don’t want to stand out quite so much.

Green hair might not be conventional, but fashion is certainly moving towards ‘different’ hair colors these days, and if you want to keep up with trends, whether for everyday use, or possibly for a party or some other event, then these brightly colored dyes are ideal for creating a really dramatic new look.

Green is certainly jewelled effect shade, and the huge color palette within it means that there is a shade out there for everyone. Whether you mix it up to achieve that beautiful mermaid look, or you go for a full block shade of varying intensity, green is certainly the new black on the fashion block!
