Conduct a strand test.

It’s important to conduct a strand test before applying the bleach to the entire head of hair. Apply a small amount of bleach to one strand of your hair, and wait ten minutes. If you’re not satisfied with the result, apply another layer of bleach and check after another ten minutes. Rinse and dry your hair to see if you like what you’ve achieved so far. If not, keep going until you get the desired result!

Protect your clothes, your sink and your skin.

• Wear old clothes you don’t mind ruining.
• Put on a smock or an old T-shirt to protect your clothes from dye stains, and wear gloves to protect your hands from the bleach solution.
• Protect the skin on your forehead and ears by covering them with plastic wrap, which will shield those areas from any splatters or drips of water that might accidentally get thrown onto them during the application process (this is especially important if you have dark hair).

Divide wet hair into sections and apply bleach one section at a time.

When you are ready to apply bleach, make sure you are wearing gloves. You may also want a tint brush on hand for this step. The tint brush is used to apply the bleach evenly across all of your hair and make sure it covers every strand. If you have any bald patches in your head, be sure to do a little extra work there so that there aren’t any spots left out when it comes time for rinsing out the bleaching solution.

Now that we have covered how much bleach should be applied and where exactly it should go, let’s talk about how long this process should take place! The amount of time needed varies depending on how light or dark you want your final result to be but generally 4-5 minutes per section will suffice if using 40 volume developer (or 1 oz of 40 vol per pound). This means if you want really pale platinum blonde hair then one hour would probably suffice (20 sections = 20 ounces total = 20 oz x 1 oz = 20 x 40 vol). If your goal is something darker like auburn reds/dark blondes/light browns then 5 minutes per section may be necessary instead—but again this depends on what exactly *you* want! For example: A dark brunette with reddish undertones might require less time than someone who has only ever dyed their hair black before.”

Work through each section until you have applied bleach to the entire head of hair.

• Work through each section until you have applied bleach to the entire head of hair.
• You may want to use a dye brush, or even your hands, depending on how long your hair is and how many sections you are working with. Be sure to saturate the hair with bleach; this will help you get an even distribution of color when it’s time for coloring.
• Use a comb or other bulb-shaped tool (like a bottle brush) to gently comb through each section as you go along. This will help ensure that all areas are evenly colored and there are no missed spots!

Blend the faded ends with the freshly bleached roots.

If you have already bleached your hair in the past, it is possible to just blend the faded ends with freshly bleached roots. This is a good option if you have already lightened your hair to a certain degree and do not want to bleach it again.

To apply this type of bleach, use a clean brush and work the bleach in while feathering out from the root area. A feathering motion allows for even distribution throughout the hair shafts, helping them maintain their structure while creating highlights at varying levels of lightness. Be careful not overdo this process as it can weaken or damage your hair!

Let everything process for 30-60 minutes, or as directed by the developer’s instructions.

Once you’ve mixed your bleach, let it sit in your hair for the full amount of time suggested by the developer’s instructions. This may be anywhere between one to three hours (or more if your developer is left on longer), so make sure that you’re prepared with snacks and Netflix before getting started.

Don’t leave it in for too little or too long! It can turn out disastrously if you under-develop or over-develop your hair—so make sure that you follow the instructions carefully.

If this seems like a lot of work, don’t worry—there are plenty of YouTube tutorials that walk you through each step from start to finish!

You can safely execute a DIY color job with the right supplies and knowledge!

While you can execute a DIY color job with the right supplies and knowledge, the process is still not as simple as running to your local drugstore and picking up any off-the-shelf box of dye. Safety precautions are an absolute must when handling bleach. Follow these safety tips before you start:

• Know what you want to do before you start. If this is your first time coloring hair at home, it’s important for you to know what kind of look or color variation best suits your face shape and personal style so that way when it comes time for application day, nothing will go wrong! Also keep in mind that there are many different types of dyes available on Amazon; some may require specific instructions which might differ from others so make sure that if needed then get some help from someone who has done this before (like myself!).
• Prepare the area ahead of time by covering furniture surfaces with plastic wrap or newspaper – use rubber gloves throughout entire process because we don’t want anything getting into our eyesight while doing something as delicate as dyeing one’s hair! The last thing we need after all those hours spent shopping around town looking pretty would be having some very serious eye problems afterwards due again lack attention towards detail during preparation phase itself.”
