Prepare yourself.

Hair dye is permanent and damaging. If you’re not sure that you want to keep your hair dyed green, don’t bother with it. Instead, try a temporary dye first. That way, if you don’t like the color or decide that it’s too much work for you, there’s no harm done besides having to wait until your roots grow out again (which usually takes about 6 weeks).

One other thing to consider before getting any coloring product: what kind of damage might this do? If this is something which will cause my hair to fall out or break off in clumps or any other terrible thing that could happen with dyeing, then I won’t be using it!

Research the product.

You can research the product you want to use by looking at reviews, reading up on the ingredients used in each dye and also seeing images of people who have used that particular brand. You should find a color swatch that is similar to what you want and place it next to your own hair so that you know how this color will look on you.

The best way to do this is by using samples for testing purposes until you’re 100% sure which brand is right for your hair type, length and texture.

Pick out your color.

In this section, I will help you pick out the right color. Before you do anything else, consider whether or not your hair can handle the dye. If it’s very damaged or thin, you should probably avoid trying to dye it a bright color. Instead, stick with something more natural-looking like red or brown.

If all goes well and everything turns out as planned when you go over to that friend who dyes their own hair all the time because they’re obsessed with doing DIY stuff in their free time (this person exists), then congratulations! You now have an awesome new look that everyone will be jealous of!

Decide if you’re going to bleach your hair or not.

If you want to dye your hair a color that is not naturally found in your hair, such as green or purple, then bleaching is necessary. Bleaching will lighten the color of your hair and remove any natural pigments. If you do not want to bleach, there are other ways of getting colors like these into your hair but they may not stay as long or look as vibrant.

If you’re still interested in dying without bleaching then proceed onto the next section!

How to bleach your hair.

Bleaching your hair is the first step in achieving a bright, green hue. It will take about three hours to achieve the desired result, so you’ll want to make sure you have enough time on your hands before starting this process.

First, get all of your supplies together: bleach and developer (in paste or liquid form), gloves, a brush and bowl for mixing, clips for sectioning off sections of your hair. Once everything is laid out on a table in front of you, get started by mixing up some bleach according to the instructions on its packaging—usually 1 part bleach powder or crystals per 10 parts water. Depending on how much product is specified in the directions (it varies depending on brand), use less than half a cup total; fill any remaining space with water until there are roughly two cups total volume. When it’s mixed together thoroughly without clumps floating around at the bottom or sides of the container it should look like milk! Now that we’ve got our mixture ready let’s start applying it!

Use a toner if necessary.

When you’re done dyeing, it may look like you didn’t get a very good color change. Don’t worry! If there are still some spots that are more yellow than green, use a toner to make sure the dye is fully fixed in your hair. A toner will help eliminate any leftover yellow or orange tones from the dye job and give you an even greener coloring.

You might be wondering: what exactly is a toner? A toner is often mistaken for bleach because they both aim to lighten up certain colors of hair—however, they actually do different things. Toners contain peroxide (like bleach) but also have dye in them which allows them to change slightly darker shades into lighter ones without totally stripping out color pigments like bleaches do when applied improperly or used on their own without any other products besides shampoo and conditioner as part of your regular washing routine!

If you want more information on how exactly using this type of product works then read up here before continuing down below so we can get started talking about how much easier it can make getting those perfect green locks!

Dye your hair green.

There are a few different ways to dye your hair green, but the most effective method (and my personal favorite) is using the bowl and brush method. This requires little more than a bowl, some water, a comb or brush, and your chosen colorant. First you’ll need to prepare an acidic solution by mixing roughly 1/2 cup of vinegar with 1 cup of water in a medium-sized bowl. Then take another large bowl filled with cool water and place it on top of a towel so that you’re able to comfortably dye your hair without making too much of a mess on the countertop or floor.

Once you’ve got all your supplies ready, apply the dye using the following process:

• Section off about an inch square piece of hair at each section where you want to apply colorant.
• Dip one end of your sectioned piece into the acidified solution for 30 seconds or so before brushing it through with either an old toothbrush or wide-tooth comb . Make sure that as much surface area as possible gets covered in pigment; if any areas appear lighter than others after applying pigment then simply touch up those areas by dipping again briefly before brushing through gently again.* Repeat these steps for each section until satisfied with results; remember not to leave any sections unattended too long because this could result in uneven results! It’s best practice when using such concentrated solutions like this one because they tend not to be diluted enough by themselves—even if diluted properly first — which means we’d be wasting our time doing anything other than waiting around while half our head lolls away under cold running water while everyone else gets their job done faster than us.”

Fix any mistakes.

If you’re not happy with the color, try another shade. If your hair got damaged by the dye, use conditioner to repair it. If you’re running out of time and don’t want to fix anything more than the most basic mistakes, use a toner instead of conditioner. And if you’re color is fading due to water or general wear and tear on your hair, just add some toner in there! It’s much simpler than going through all of those steps individually.

Maintain your color!

You’ve gone green, or you want to. You might have heard that it’s hard to maintain the color once you dye your hair green. However, with a little care and know-how, you can keep your brilliant hue for years! Here are some tips on how to care for your colored hair:

• Use shampoo and conditioner made specifically for colored hair. These products work better than regular shampoos because they don’t strip away all of the color from your strands as quickly.
• Use heat protectant products before you use any heat styling tools (blow dryers, flat irons). Heat can fade out whatever shade of green or blue you choose so it’s best not to risk it!
• Wash only when necessary (once every two weeks is ideal), but remember that dandruff-causing build up can be bad news for dyed hues! Make sure any treatments are safe for colored locks like ours before using them regularly; otherwise we may end up with more problems than we bargained for..

Green hair is attainable and not that hard to keep up with

You can get green hair if you have bleached hair. You need to use a color depositing shampoo, such as Manic Panic, or Lush’s Dream Cream Shampoo and Conditioner. If you use the Manic Panic shampoo and conditioner then add some avocado oil or coconut oil for shine and moisture.

You should also make sure that your hair is damp when applying the dye because it will set faster on dry hair than damp and wet. If you have dark brown or black hair, then it’s best to bleach your strands first with a lightening kit like Feria in order to achieve a lighter shade of green that won’t fade as quickly over time (you’ll probably want to dye every month).
